Thanks for another good one, Adam, you are a great teacher! I am 69 and have been model engineering for a year, learning much from you, Keith Rucker and Lyle P. Keep 'em coming!! John, Cardiff, Wales.
My uncle was a machinist in early 80's and he has always had this great since of "patience". He has always told me "slow down what's the rush". It's something I see in you and your videos. Keep up the good work!
Yep, Dad's tools still live in Dad's box. I treat all that stuff like he's still around because in that way he is. Can't tell you how many times I've found what I needed to finish a project in his collection of scrap metal etc. Every time I smile and say "thanks Dad, you're still looking out for me!".
This is a really cool series of episodes. I think you're making a huge contribution to your trade. Word of mouth is the old school way of learning any trade, and your series is bringing those basic skills to a huge group of people in that old school way. (Maybe with fewer kicks in the butt.) Way to go, Mr. Booth.
Perfect timing! I have been watching you and the Keiths and a lot of the other TH-cam machinists for a few years and I just bought my first lathe. You and the others are so generous with your time and talents. Thank you so very much.
Man you have a fortune in reamers ! I have a lot of reamers from a naval base and a lot of drill bits from there that were handed down to me by my uncle that worked at a naval base he was a machinist there from WW2 until 1987 and he was one of the greatest machinist ever! I take pride in using these tools and taking good care of them! I tried figuring up the value of what all these reamer and drill bits would cost and what I came up with half way through is more money than I have ever thought of having in my life time!
Thanks for posting. I bought a medium size lathe 2 years ago, got enough tooling to start using it almost every day for my DIY projects. Your videos are much appreciated, plus you look like a nice guy.
Thank you for sharing your knowledge. So many Machinists nowadays don't like to share knowledge. So I really appreciate you taking the time to videos like this.
Excellent tutorial. Cleared up a couple of things I didn't know. I do know not to turn a reamer backwards. A few years ago I ruined a set of adjustable reamer blades that way and, like they say, mistakes are the best teacher.
Thank you for reaming me out properly! Seriously, I appreciate the instructions. We have very few reamers and I realize now we have a Morse taper reamer that goes to our old drill press. Greg
Great video. I thought I knew all I needed about reamers until I watched this! Your take on cutting tools, inserts, angles etc would be a good topic I'd like to see.
I was not aware of "never" reversing a reamer which makes perfect sense. Thanks much. It is the same for a file and I often see TH-cam videos where a file is used in a scrubbing action by someone working on a project. Aargh!!!!!!!! Always love the "Abom Torque" reference which is self explanatory.
Thanks Adam. I have the same drawer full of adjustable reamers that were passed down. I have always treated that drawer as sacred ground. Never used them. As a result of your post, I am going to give-em a go. Thanks again for the time and info.
Thanks for making these videos. I know alot of the older guys probably already know this stuff, but its great info for the newer guys. Keep up the great work Adam!
Hello from France Adam and thank you for this very interesting video. You mentioned that you don't rely on the reamer for precision hole. For precision reaming with accuracy close to 0,01mm, you can use a floatting chuck. Its a pricy extra accessory, but can be found for adapting on a Lathe tailstock (reamer is fixed) or milling spindle (reamer is turning). It's used to correct misalignement between the axis of the spindle (or tailstock) and the hole to ream. It also gives the advantage of letting the reamer following the true axis of the hole. Generally speaking, the reaming using floatting chuck can have the tolerance of the reamer itself. Floatting chucks can be found with Collet MT or straight flange mounting, and reamers can be mounted with ER Collets, or MT attachments. Some models can even allow internal coolants to pass through. Have a good day ! François
Adam, thanks alot bud for showing us newbies and teaching us through your videos. There is alot of things that I needed to figure out around the shop and I always go to your channel first. Thank you.
Thanks for the video, I bought a bunch of tooling from a friend who needed some cash and have been trying to learn as I go along. Not easy at all but thank god for yt and people like yourself, K Rutcker and pete222. The simple videos are sometimes the most helpful. Keep up the good work and remember not all of us are machinist and I will continue to watch and learn.
I was going through my inherited tools this morning and found a big beautiful set of these funny looking drill bits which I now know to be reamers. Thanks for the vid.
I was looking for info for pull reaming and the reaming stock allowance/removal, but I appreciate the additional knowledge about reamers. Thank you sir
Great video. I'm new at this and you explained a lot to me. Thanks again. The question I had was answered by you already when someone asked when to use a reamer. Great videos. Thanks for not forgetting about us new guys. Enjoy your videos a lot.
one thing I'd like to add is, if at all possible don't peck with a reamer, you'll end up with a bigger hole, I don't know why that's just my experience. thank you Adam. loving the content. keep it up!
robert hughes You never peck with a reamer. It will screw up the hole every time. In gunsmithing to chamber a rifle barrel, you use a high pressure flushing system to flush the chips ahead of the chambering reamer for this very reason if you are doing precision chambering. Excellent comment.
Love your videos. Stumbled on to the machinist type channels with Keith Fenner and Keith Rucker. Found yours as well. So I started with your first and worked my way up to this year so still catching up. Your videos are easy watching and full of information. Even though I don't do any machining it has changed how I tackle problems I may deal with on a day to day basis. Basics are always good especially for people like myself Many Thanks Adam
sometimes you can use a box socket as a handle by turning it upside down and placing it on to the reaming tool, get 12" of bar and weld to a nut in the centre, then put the nut inside the socket, use the square drive size 1/4" 3/8" 1/2" n so on that fits your reaming tool size, this should be as good as any handle an hopefully it helps somebody thanks for the vid Abom👍
I have cleaned up the tailstock on 2 lathes with that tapered reamer you showed. Worked well as they were not gripping because of burs, but after they did.
Good video, Adam . I was digging thru old videos hoping to find "salvation" for my reaming . I like you could never find reliable accuracy with my reamers . I was dead-sure I must have been doing something wrong -- could never find a solution to reliably get any better than a thousandth or two -- would always have to rely on honing . Got a "kick" out of seeing your inherited reamer-drawer ! ...... looked very familiar . It's is amazing the weight those old lower boxes could handle -- albeit, not without a little distortion .
That was a great presentation boss thank you. Im new to machining. I. Restoring a 1966 f-100 pick up and needing to learn stuff like reaming kingpin bushings and such az a lot of shops wont do it. Great video👍
You say you don't like to rely on reamers for precision holes then what do you use? I thought that was the intended purpose of a reamer. I've also had problems getting a precisely reamed hole myself but haven't figured out a better way. Kinda figured I was just doin something wrong.
Great video Adam! Thanks. I know that I have seen better than 90% of your videos but have you done one on end mill cutter? More specifically the purpose of 2, 3, 4, 5, 6... flutes? i.e. What material they are good for and whether are better for roughing or finishing? I hope I am asking that correctly. Again thanks for all you do!
not a problem for you and me though. my friend call me when they want me to put the mule on it . most of my friends are tiny folks lol. still fun to watch thoses light weight guys hang on the wrench
Great job Adam! This will be a great series. I would suggest creating a "Tooling Basics" playlist for all of these videos to make it a little easier for people to find everything and have it all in one place. Thanks for freely sharing your knowledge and experience as is appreciated. Open Source knowledge, software, and hardware in the way of the future and we are in the early stage of implementing all three. Peace!
Adam, How sharp is a reamer and can one sharpen one? It would seem to me that throwing them in a drawer where they rub together would dull them. Would not organizing them keep them in best shape?
Henry Carr Most reamers have center holes in the ends to hold them between centers on a Tool and cutter grinder to sharpen them. This is the only way true accuracy can be obtained. Throw all of your cutting tools together in a drawer if you want to nick them up, especially reamers.
Purchased some huge ( long) reemers at a show and tried to use them in the 10" lathe. 1 inch for reaming a model engine cylinder. The flutes would catch in the work every time. Didn't know you weren't supposed to use power! Any special technique other than what you showed for larger sized reamers? One inch up to 1-1/8 ?
Hey Adam, what about speeds and feeds when reaming in a machine, I was always taught low and slow, that you run a reamer at 1/3rd of its drilling speed as a rule of thumb, yet I've seen guys I work with run them at the same speed as they would drill at. What would you recommend?
i have a question is it better to predrillwith different drill sizes ? (small diam and mid diameter) for taper reamer ? or drill straight minimum diameter and then the ramer ?
Buy one of these and hot dip them (blocks of oil/wax go in to be melted). I used to send my tools out to customers as the dip protects the edges from chips and corrosion. www.ebay.co.uk/itm/KENNEDY-RED-HOT-DIP-MELTING-POT-VAT-INVOICE-/191909334311?hash=item2caeb00d27:g:a9IAAOSwhOVXc8CP
does the adjustable blade reamer only cut in one direction? what I mean is if you turn it to the right it will cut but it won't cut when turned to the left? Is that the case?
I've cheated and used a center punch chucked in a drill press as a guide before. Same idea as a spring loaded tap follower, but I didn't have one of those on hand. It keeps the back end of the reamer from wandering around. Thanks for the info. Never knew what the sprial reamers were for. I always figured it was something for heavier cuts to clear chips.
A solid center point works just as good or better, but you have to keep a hand on the quill handle to use it. I've done it that way countless times for tapping holes.
For me fixed reamers are ok for reaming to precise size hardened shafts but for axles I turn I'm just not that good I can size the shaft well enough to use a fixed reamer and need that adjustability to give me some wiggle room to ream to clearance I want.
Hey Adam great video as usual. After getting rid of some of my Dad's machinist tools (He was machine shop foreeman at CIL industries in Edmonton Alberta) I now truly regret it. Suggest you keep what you got for your future kids. Things change in time sometime things happen really fast when one's not expecting it. Rod
Adam, could you please inform us how we can identify machine reamers on the website of Brownells? The thing is that we need to order a machine reamer however on the website in the description of reamers the information about the type of reamer, namely machine reamer is absent and I cannot understand how to find machine reamer, due to which specifications? Thank you in advance for your time and assistance. Best regards, Ukraine
Awesome video and wonderful shop! Wi can see the history it has! I live in Brazil and my dad has a front cutting plier made in the US that belonged to my granddad: though it has been very used it's still in perfect contidion! I found your video looking for how to use hand reamers. I want to enlarge a slot car aluminum wheel to fit a 1/8 axle. The wheel's bore is 1/8 but it's not fitting the axle. I found a 1/8 manual reamer with d1 1/8 H7 and d2 1/8 e9. Do you think this will do the job? Thanks!
Thanks Adam you confirmed something I felt for many years now. I’ve been in the trade for a little while now, about 38 years, and I like you do not use the reamers for the reason that I don’t trust they will cut an accurate size hole. I just settle on boring the hole instead of possibly scraping a part.
Couldn't remember what these tools were called so after watching part 1 of your 'new lathe' delivery setup I said main lemme look in his previous videos I know I will at least see a picture...sure enough landed right here. Need to 'ream' an inch diameter (i/d) pipe a lil ways to accept a 3/4 in pipe which the outside diameter is 1-1/16" nothing critical as you would say but hopefully I can do it with a hand drill about 6-12 inche depth for an adjustable type stand.
The beauty of a tapered pin is it will release very easy as opposed to a straight dowel, and in toolmaking of die blocks to shoes as in progression dies for instance, a threaded ejector hole will release the die block immediately, straight dowels need to be completely driven out with a hammer and punch, plus two parts taper doweled together can be realigned (moved) into alignment by re-reaming, you can't do that with a standard straight dowel if the alignment is not exactly spot on its time to go with an oversize, I have used tapered dowels recently on several tools I have built, they might be old fashioned now but I think they look much better than a set screw to locate a hand wheel on a shaft, and they work great, Edmund...........Alberta
Good overview Adam, I'm glad you mentioned the chuck / collet holding thing I've been burned by that before using a drill chuck instead of a collet especially for smaller sizes. I would have liked to hear your thoughts on the actual operation in a machine, like pecking or not and speed, etc.
Yes, I've heard different things like you should not peck drill with a reamer, etc. Also I've been told about %2-%3 is what you want to leave for the reamer to cut.
+RussZHC The over/under sizes are ground to a specific size typically around a nominal size. Say 1/2", under could be .499. That could be used as a press fit for a pin, or .501 which gives a little clearance while still providing a clean precision hole.
Adam, I work a lot with tapered metric pins. I've seen a lot of tapered reamers for sale lately but I was wondering if they aren't US Standard and not metric. Is there a standard tapered pin or are they all metric? The number ten you show looks very much like a metric pin taper for 10mm din h7 holes. Also, I wanted to let you know that shockingly, you can taper ream a straight hole in must cases. I'd be hesitant to do something like an m4 from a straight hole but in a pinch it can be very handy.
I have 4 of those adjustable reamers hanging on my shop wall.. Never used them, didnt realy know how to use them. You can use a socket with 12 dividers and a sliding t-bar on those big 4 siders
Watching these kind of videos ensures I will never be able to retire as all my savings constantly gets diverted to more tooling!
I wouldn't think there's too much cash left after your barn build.. haha
Money has certainly been going out faster than it comes in!
Isn't that Baily's retirement???
The barn will be Bailys rest home:-)

is it better to predrillwith different drill sizes ? (small diam and mid diameter) for taper reamer ?
or drill straight minimum diameter and then the ramer ?
Adam, should you ever peck drill with a reamer - like for chip removal on a deep hole?
Very nice video. But I wonder, what do you use to get that "fine tuned" hole, if you don't trust/like reamers?
What kind of speed do you want to use on aluminum holes and also copper bushings?
Any chance of a video on correct storage of machine tools ( do's and don'ts ) ? Lathe chucks , endmills ect..?

Reamers are good to enlarge a hole, is the a tool to bring down in size, example: bring down from 0.625 to 0.500 a stud that is in place ?
my understanding of adjustable reamers is that aside from compensating for sharpening you can also tune in running or press fit etc.
Do you happen to have a bushing install/removal kit that you could demonstrate how to use?
great vid bud, always cool seeing different stuff...
For me fixed reamers are ok for reaming to precise size hardened shafts but for axles I turn I'm just not that good I can size the shaft well enough to use a fixed reamer and need that adjustability to give me some wiggle room to ream to clearance I want.
Thank you for this. The vid on taps was great too.
Hey Adam great video as usual. After getting rid of some of my Dad's machinist tools (He was machine shop foreeman at CIL industries in Edmonton Alberta) I now truly regret it. Suggest you keep what you got for your future kids. Things change in time sometime things happen really fast when one's not expecting it. Rod
Very informative Adam ! I have only used reamers to do valve work on heads .. Thumbs up
Adam, could you please inform us how we can identify machine reamers on the website of Brownells? The thing is that we need to order a machine reamer however on the website in the description of reamers the information about the type of reamer, namely machine reamer is absent and I cannot understand how to find machine reamer, due to which specifications? Thank you in advance for your time and assistance. Best regards, Ukraine
Good one Adam. Thank you for this great video.
Can't you use an adjustable reamer also to create different fits for a given nominal/basic diameter?
Awesome video and wonderful shop! Wi can see the history it has! I live in Brazil and my dad has a front cutting plier made in the US that belonged to my granddad: though it has been very used it's still in perfect contidion!
I found your video looking for how to use hand reamers. I want to enlarge a slot car aluminum wheel to fit a 1/8 axle. The wheel's bore is 1/8 but it's not fitting the axle. I found a 1/8 manual reamer with d1 1/8 H7 and d2 1/8 e9. Do you think this will do the job? Thanks!
Thanks Adam you confirmed something I felt for many years now. I’ve been in the trade for a little while now, about 38 years, and I like you do not use the reamers for the reason that I don’t trust they will cut an accurate size hole. I just settle on boring the hole instead of possibly scraping a part.
ok i have a question. How big was that shell reamer in the box?
Couldn't remember what these tools were called so after watching part 1 of your 'new lathe' delivery setup I said main lemme look in his previous videos I know I will at least see a picture...sure enough landed right here. Need to 'ream' an inch diameter (i/d) pipe a lil ways to accept a 3/4 in pipe which the outside diameter is 1-1/16" nothing critical as you would say but hopefully I can do it with a hand drill about 6-12 inche depth for an adjustable type stand.
Can i use ajustable reamers in lathe and milling machine or only hand use?
Thanks for recognizing us beginners!
What is the difference between straight and spiral flutes working functions ?
The beauty of a tapered pin is it will release very easy as opposed to a straight dowel, and in toolmaking of die blocks to shoes as in progression dies for instance, a threaded ejector hole will release the die block immediately, straight dowels need to be completely driven out with a hammer and punch, plus two parts taper doweled together can be realigned (moved) into alignment by re-reaming, you can't do that with a standard straight dowel if the alignment is not exactly spot on its time to go with an oversize, I have used tapered dowels recently on several tools I have built, they might be old fashioned now but I think they look much better than a set screw to locate a hand wheel on a shaft, and they work great,

adam , question; have you bored any 19" long cylinder sleeves in the past, pretaining to antique equiptment. i enjoy all your machining demos.
Good overview Adam, I'm glad you mentioned the chuck / collet holding thing I've been burned by that before using a drill chuck instead of a collet especially for smaller sizes. I would have liked to hear your thoughts on the actual operation in a machine, like pecking or not and speed, etc.
Bill De La Vega You talking about actually teaming a hole in the machine Bill?
Yes, I've heard different things like you should not peck drill with a reamer, etc. Also I've been told about %2-%3 is what you want to leave for the reamer to cut.
What is the purpose of the "over/under" sized reamers? Does it have to do with fit of the mating parts?
+RussZHC The over/under sizes are ground to a specific size typically around a nominal size. Say 1/2", under could be .499. That could be used as a press fit for a pin, or .501 which gives a little clearance while still providing a clean precision hole.
Adam, I work a lot with tapered metric pins. I've seen a lot of tapered reamers for sale lately but I was wondering if they aren't US Standard and not metric. Is there a standard tapered pin or are they all metric? The number ten you show looks very much like a metric pin taper for 10mm din h7 holes. Also, I wanted to let you know that shockingly, you can taper ream a straight hole in must cases. I'd be hesitant to do something like an m4 from a straight hole but in a pinch it can be very handy.
I have 4 of those adjustable reamers hanging on my shop wall.. Never used them, didnt realy know how to use them.
You can use a socket with 12 dividers and a sliding t-bar on those big 4 siders
