- If you missed it Part A is here: • Bored of lame tool rev...
The plastic they use in the tool housing is amazingly good quality! We discover some shocking news about the gears in the grinder. We also confirm what type of lubricant is being used and see why the Dewalt marketing department can get away with the crazy specs on the box.
0:30 BASF high temperature plastic housing
3:00 What a quality trigger switch looks like
5:00 Marketing BULLSHIT! Busted on the Horsepower Rating!
6:00 Motor wire is solid (stiff-breakable) not stranded (pliable)?

7:25 Motor Amperage testing
10:25 Heat buildup after running checked with the FLIR
11:06 Locked rotor torque amperage test and thermography
13:20 Heavy grinding test - blows breaker 30A!
13:50 Heat buildup in steel during grinding - interesting!
15:30 Intermission sponsored by Kizmox and Finland!
17:15 How do manufacturers rate power, torque, amps and RPM?
21:00 Testing the grease is it graphite or moly?
23:10 Testing the gear for copper infiltration (to increase density)
24:00 Brimstone test
25:00 That didn't work, like, at all.
25:50 How Moly works
27:00 Geology streak test for molibdenite, how to check for moly

you should make an Ave frankengrinder... the best parts from each.
- Who's the prime minister?
- What day is it?
- What's the firing order of a Chevy small block?
Oh, now I get it
@@The_R-n-I_Guy I don’t get it plz explain
@@dom8420 when he was checking if he was having a stroke he answered those three questions to verify.
What is the firing order on small block

LMAOOOOO that Finland halftime show was pretty friggin hilarious
I gotta say, I really like your videos. I like the informative nature, as well as the funny asides (Finland and the monkey with cymbals, etc)
I just watched a 40 min two part video on a grinder, and I don't even own power tools or work with them. I don't know what I am doing with my life anymore.
+sTEPHEN sHIELDS Same here, but I was interested the whole way through :) Great vids.
+Brandon Brown
Science bitch.
+sTEPHEN sHIELDS same i could care less about tools but i watched this and the previous video, i also subscribed just because i like the guy doing the vid, my life is nothing
+sTEPHEN sHIELDS Well, i see these videos as kind of a wake up call. 90% of what we in the western world buy is basically overgloryfied, overprized, overadvertised gold platet shit in a nice box.
so fucking true
It's 3am, I have work tomorrow morning, I've never considered buying a grinder.
Why have I watched 2 parts of this review at approx 30min a piece?
Excellent review! I love how detailed you get.
''real degrees, not american pesos''
subbed
I cant believe I just watched not one but TWO full half hour videos on a topic I neither care that much about or know that much about. A massive credit to your entertaining and informative presenting skills my man. Seriously conisdering subing
***** Just to teach you a lesson for that sarcy comment I just subscribed so there Mr AvE
Cripes, I know this is old, but jeezlus. Twigg and Dingleberries.. So glad I went this far back. That one is a keeper wah.
Dollar Pesos, no kidding.
I'm moving to Canada and away from the Mexican boarder if all Canadians are like you, great vids
Real tears came out of my eyes at the Finland intermission. Great stuff!
So... a neutron walks into a bar and asks -"How much for a beer?" and the bartender answers -"For you, no charge".
Lol
I just laughed so hard when you told about sauna :DDD
***** someone in my family is Finnish and what he said is all true
Dixon Cider I'm from Finland too! That's why it was so funny :)
+Dixon Cider I'm more surprised by how someone could find this shocking. Pfft, junk, tits, who cares, it's a sauna.
+Dixon Cider Someone in your family is Finnish, but you dont even know who? But you still know it's all true? :D
Dixon Cider is it true that some girls love Dixon Cider ?
I don't even need one of these grinders, but these videos make me want one...
maybe i should get one for my dad.
@AvE Great review. Especially from a Makita fan boy as I have been for years as well. I only wish you didn't mention a price for the switch. Maybe, just maybe, Dewalt only charges $24.95 for a replacement switch but now if one of their business type dudes watched your video, they are now going to charge $40.00. Outside of my totally misplaced issue with switch pricing, you are without question, the man. You sir, have experience, knowledge & smarts far beyond the average uploader on TH-cam, but I'm sure you must know this already. As an aside, aren't most if not all mass produced power tool gears, pressed powder metal nowadays?
Nothing beats a solid, skookum, intelligent Kanuckistan who knows what he is about. Cheers mate & thanks for all your in-depth reviews & entertaining videos. You are the sort of fellow that most of us wish we had as a neighbour & friend & would gladly raise a pint with, if you indulge in that sort of carnal activity.
Recent subscriber, fellow Canadian & looking forward to whatever you have up your sleeve for your next video. I laugh my ass off at your deeply twisted, darkly tinted, extremely juvenile & very witty sense of humour.
Well said.
Don't worry the switch will out last the gears. I worked maintenance in a meat packing plant about 10 yrs. ago and the Dewalt grinders wouldn't last a year and it was always the gears that went bad. Maybe a little lube would help. They will also shock the crap out of ya when sanitation hoses you down while your trying to work.
7:47 love the chev firing order mental faculty test
4 years late but indeed you are correct. customer dropped off a grinder for repair and the only damage besides the lock button is that big crown gear. multiple teeth in multiple spots around the gear. i will never get bored of your videos
Another thumbs up from me. I appreciate the work you put into these. Very original, very personal, very fun reviews. Keep it up!
I learn more from watching your videos than I do in most of my engineering classes.
Your tool breakdown and testing of all parts is the best anyone Could hope to find, anywhere, Thank you!, I watch them all!!
First decent tool review I've seen in years! Thanks for the real in-depth look at the DeWalt unit.
This is by far the best/most in depth tool review that I have ever seen. Subscribed
I find these vids to be very entertaining and even educational! A wonderful way to blow off a chunk of time! Thanks Ave!
Your tool reviews are amazing! They are very informative and fun to watch. I appreciate your time and effort Sir. Subscribed.
Yep... I'm no expert, only a user and this confirms why my first and last DeWalt grinder crapped out on me. GRrreat review.
Even if the case would melt at 2000 deg. I'll let go way before that...
Great channel, great reviews us Canadians are a bunch of our own...!
Pierre
This reminds me at times of regular car reviews, just for tools. Great videos!
Really appreciate the detail of your reviews. Very knowledgable and very entertaining. Please keep doing what you're doing.
Canadians always have the best TH-cam channels! Good shit dude, keep er up!
Very cool. Informative, unbiased, and you're almost akin to a mad scientist. I'm completely entertained and a fan for life. Hope you continue making videos like this.
don't know how i did not find your channel until now. Awesome reviews, very technical and thorough. I will donate, do keep up the great work! I subscribed.
I use lighter wheel bearing grease when I have grinder heads apart because it flows much better than hard moly grease which tends to accumulate away from the gear teeth.
I don't know how but this video is even more interesting and informative than part A, thank you so much for these!
Your stroke test hit home with me, it's something ill always remember now.
You know that you can disable or change the time-out of your Flir? (settings->scroll down-> clock icon)
Love your videos!
This is really NOT a lame review. Good job man, you really going into depth. In compare to some channels who would just unbox and try tool and call that review.
Best tool review I've ever seen.
i love it when you talk Canadian.
+AvE your something else. are you engineering in the stand up comedy field? or stand up comedying in the engineering field?
Dude when you got on your Finland rant I died. Nearly choked on my food with the Aqua Velva shit.
Why can't I like these videos twice? Best tool video's ever man, great to see how these things chooch.
Love from the Netherlands!
holy crap did i just watch a full hour of a tool review?
Cr42yguy yes! And it isn't a complete waste of time!
Thank you for the explanation on the graph. Very informative and interesting.
Both episodes were outstanding!
i dont know about any one else, but i appreciate your assessment of the solid vs stranded wire. that is a little known and often over looked fact.
At the shipyard I work at, we have a lot of the 4" grinders.
The gear set housing tends to snap right at the flange leaving you just the pinion gear sticking out.
So I think you're right on the money that the gear set on this bad boy would go first.
I love how remembering the firing order for Chevy V8s is how you test for a stroke.
Great in-depth review. Also very enjoyable to discover your wealth of knowledge.
Thank you.
man you slayed me with the meth lab in Guadalajara comment.
xpoohx105
And the intermission part. OMG hahahahahahha.
These are proper reviews man! Thanks.
it's good that you did a self check when you smelled the smoke and it's nice to know you even know the firing order of most small block chevys
The Finland part , made me spit out my beer , love your vids..
Great video. You might look into a power factor reading watt meter. They'll often kick out voltage, wattage and amperage as well.
Thanks for all the awesome teardown vids! It's the only way to find the truth behind all the smoke and mirrors. I'm learning some usefully math as well. Keep up the awesome work I'll keep learning from it.
You explain everything perfectly. Definitely subscribed!
been using my dewalt 4.5 inch alot of times with over sized 7in disk cutting disk as well as the 7in cutting/grinding disk if I had alot to cut and gring (reckless yea I know) for over 7 years now. I use mine for mostly automotive repair and fab work. till this day it still works like it did day 1 (doesn't look like day one any more). very reliable, it was the first grinder I purchased and never had a reason to get another. I've used it to cut upwards of 3/4in steel plates hardened steel, plastic, stuck a circular saw blade in it and cut wood. it just never seems to quit no matter what I put it through.
Dodge firing order to check for stroke, funny! Loved the review.
Best reviews on youtube, hands down
haha chevy firing order!!!!!!! Ill never ever ever forget those numbers! Lifeline checklist to see if im tarded or not!!
Thanks for the pitter patter, let's get at 'er. Picked it up from an old timer myself but always get looks.
I love these tool review keep them coming and keep your stick on the ice :)
Great video! Answered any and all questions I possibly could have had. Love the expressions and the familiar accent as well.
Ha I guess ill do better next time too!
You're story of Finland was hysterical!
Gotta love those Canadians with their sense of humor
Really enjoy your videos! And would definitely enjoy a "snap-on" tool review if you can get your hands on one
Im pretty late to the channel, but wow, this is impressive. Appreciate ya fella! Good times!
hey man, i just found your videos today and i gotta say, i really enjoy watching them. i don't know much about machining or engineering, but i feel like i learn a lot from your videos. also, you're hilarious. seriously though, i'm glad there are people like you making these sorts of videos.
5 years later..ya still watching him?
@@keithcurrams yeah, occasionally
@@nathanbaeyens2856 Awesome! Loved that comment man, my thought exactly.
Awesome work. Love the vid and commentary
that part about finland has me laughing in tears cause its completely true xD
Been watching some of your vids these last couple of dates. The videos seems great but now I have to subscribe because of that Finland thing.
Would love to see you do this with a Metabo grinder. I know they're expensive but having worked in fabrication they're all that ever lasted in our shop
Best intermission story ever!!! oh.. review was good too!
After stumbling across this channel by accident I've been watching videos on tools that I most likely will never own or operate. Thanks for the great information.
I really enjoy watching your videos mate, you make learning stuff fun! Please continue to do so and dont let anyone tell you different.
Keep your stick on the ice ;-)
dude this was amazing I'm so glad I watched it! loved your ripems I have subscribed. what province are you in? I'm in saskatchatoon!
Love your complete rewiew of this grinder, most of the shitty other rewiews contains testing the shit and saying their opinion. Keep uploading, im subbing!
Is it bad that as a welder it hurt my heart to hear this grinder torque stall? That hum is the worst sound to me.
Same here. I was puckering up the whole time.
I'm not a welder but I instinctively yanked the first plug I could find, which unfortunately was the one powering my computer.
Milk Manson derp....
You'd hate Photonicinduction's channel then!
It made me fast forward it was so bad
Fucking fantastic videos, nobody does stuff like that on YT
John Grammaticus I
we had a few of these in arc welding class. they took beatings all day for over two years and never had an issue.
I'll remember if I ever think I'm having a stroke, to recite the firing order for a chevy V8. Seemed like a good idea haha.
great 2 part vid, FYI powdered metal gears are used in ALL auto transmissions, car and truck, and connecting rods in vetts and other cars and trucks.plenty of constant fluid and lub though.
Super interesting 2 videos. Amazing engineering. From Dewalt and yourself.
Keep these video comin! I thoroughly enjoy them, even if I don't quite understand all the technical lingo. Makes me wish I had spent more time in class instead of chasin tail. Well, maybe not...
Used tools from a young age and I still only understood about 30% of what you said. I did get the gist of more though. That being said I still loved this video and I was entertained and interested from start to finish for both parts. Thank you and please do more reviews like this. The various cordless drills and cordless battery brands would be so valuable.
I've been checking everyday for this video and I don't even need a new grinder! haha.
Great review and very scientific. Oh yea also very funny!! Look forward to the next one!!
Hey. Enjoying the videos . New to your channel, just curious how you learned so much about electric and machinery. I have no clue what you are talking about in most of your videos but I feel like I'm learning something. Thanks
I wonder if it woud be possible to somewhat distinguish composition of gears by measuring their hardness? Would be cool if you could measure it at your batcave for different tools etc.
Best description of Finland ever
The gravel roads around my primary school here in Norway had tons of molybdenum disulfide rocks/minerals in them. Took me some years to learn what it was!
I learn so much from watching your channel.
"A fist in the chiklets." I love you, man...
Follow up to my op. The Husqvarna comparison was between competing brands of chainsaws. Another fun and useful item to have in the kitchen.
You almost killed me with the SB Chevy firing order!
I switched from Makita to DeWalt when every cordless I had dropped broke the handle off. I have brutalized my DeWalt and so far only dusted the clutch in a D-handle SDS rotary hammer.(actually my neighbor borrowed it and was drilling spike holes in railroad ties with it when it lost fwd.) Awesome review and now I am late for work!
i like the ''ΓΡΗΓΟΡΗΣ'' plate (13:49 right after the circuit breaker), have you ever been to greece ?
btw exeptional review, thanks for all the effort.
Awesome review.
I was laughing out loud..
Thank for your humour.
Great review and hilarious side comments and stories.
I got dewalt with same powder gearbox, and in past 2 years no issues. The cable broke first, close to the cable shoes inside which was really strange, as this is no movement zone. The tool is strongly abused with way bigger discs than supposed to use with it.
I do really enjoy your tool reviews, you have to do it more often :)
Gotta say I totally enjoy your site. You are detailed but make it interesting and down to earth as well. As for the Dewalt gearset my suggestion is buy new, open her up and put some good grease in there. I bet if you had done that it would have been quieter and ran cooler and of course last longer.
just found your site love it thanks
MoS2 in non-oxidizing environments is stable up to 1100˚C, but in air, it starts to turn into MoO3 around 350˚C, whilst evolving sulfur dioxide.
Fortunately, the grease its suspended in will also keep the oxygen away, so it will be serviceable in a proper formulation to much higher than 350˚C.
Perhaps a dollop of the grease on your (rather nifty) temperature controlled soldering iron can give an indication of what the mixture's breakdown temperature might be?
Thanks for the shout-out, kind sir.
Wiki had the one reference to 350˚, but it was so vague in its application that I had to go looking for a better reference, once it was called into question. This wasn't easy, because all the molygrease makers list temps higher than 350˚. Eventually, I found this
www.engineersedge.com/lubrication/molybdenum_disulfide_characteristics.htm
which seems pretty thorough. I might have to keep that site in mind for future reference. it reads like a 70s textbook, just how I like my reference material.
Would love to see some stuff on the new DeWalt 60v and 120v chop saw, circular saw, and saws-all.
