In this extensive episode of The Router Bits, Patrick Holcombe discusses and demonstrates the real advantages of Spiral Router bits. If you haven't discovered them for yourself, then this video is worth watching...
Upcut spiral bits are so-called because when used handheld have upward chip ejection providing an excellent finish on the lower side of the workpiece. When used in a router this action is reversed, the waste is ejected under the table with an excellent finish on the upper side of the work piece.
Due to their spiral cutting edge which stays in continuous contact with the workpiece, these bits give a smooth, chatter-free cutting action, unlike conventional bits which have intermittent contact with the workpiece. Unsurpassed for cleaner cuts in ordinary or difficult materials, softwood, hardwood, plywood, composites etc.
A special super-micrograin carbide formulation was created to produce and hold a keen cutting edge. The new low-angle spiral is designed specifically to shear wood cleanly and provide efficient chip ejection. The tools run cooler and the edges last longer.
Downcut spiral bits are so-called because when used handheld have downward chip ejection providing an excellent finish on the upper side of the workpiece. When used in a router this action is reversed, the waste is ejected above the table and bit with an excellent finish on the lower side of the work piece. To note that when used for trenching operations, this can cause the router/work piece to lift due to the waste collecting in the bottom of the trench.

A special super-micrograin carbide formulation was created to produce and hold a keen cutting edge. The new low-angle spiral is designed specifically to shear wood cleanly and provide efficient chip ejection. The tools run cooler and the edges last longer.
Compression spiral bits are designed with both up and downcut chip ejection, providing an excellent finish on both the upper and the lower side of the workpiece.
Due to their spiral cutting edge which stays in continuous contact with the workpiece, these bits give a smooth, chatter-free cutting action, unlike conventional bits which have intermittent contact with the workpiece. Unsurpassed for cleaner cuts in ordinary or difficult materials, softwood, hardwood, plywood, composites etc.
The new CMT solid carbide spiral flush trim bits are manufactured with a special super-micrograin formulation that has increased hardness. Combined with the spiral cutting angle, the new CMT solid carbide spiral flush trim bits with double bearings allow the cabinet maker to sheer wood and other wood-based products cleanly, providing more efficient chip ejection than standard flush trim bits. In production settings these new bits will run cooler and the edges will stay sharper, last longer and increase your shop productivity. - แนวปฏิบัติและการใช้ชีวิต

Was just watching another TH-cam who mentioned an.upcut bit. Next up was this awesome explanation of router bits.
Thanks O.M! Glad you enjoyed it. There are dozens more router bits and techniques videos on our channel to enjoy. We have a playlist on our channel called "The Router Bits" that covers almost every conceivable router bit there is. Enjoy!
Best explanation i've seen. I now understand the difference , and the pros and cons of up and downward spiral bits. Thanks for taking the time to explain it.
You are very welcome, Howard. Thanks for your kind comment.

Really great video. So informative. At one point I knew most of this, but got busy with other things for a few years. This is a great refresher, but you provide good background explanation and other info for anyone. Thanks.
Bought a Spiral after your advice and Way better finish to my timbers. Yes the Router does feel like it is under less stress while cutting. Thank you
Great to hear!
I really appreciate you sharing your expertise. Now I can understand the value of spiral cut router bits.
Patrick, one of the best videos on TH-cam. Very informative explaining in a no BS way. I got to get a few.
Thank you, Sparkey! We will pass that on to Patrick for you. If you need to get yourself some spiral bits, this might help: www.timbecon.com.au/site-search/default.aspx?search=spiral%20upcut and www.timbecon.com.au/site-search/default.aspx?search=spiral%20downcut
This is a very good, very thorough presentation of the pros and cons of straight vs upcut vs downcut router bits
Very instructive and clear explanation Patrick, thanks a lot from Argentina
Thanks for sharing. Very good for newcomers to wood work. Learning new things everyday, thanks again.
Thank you for clarifying the differences.
Awesome. Finally a clear and in depth video about those bits
Outstanding in every way...I am sold.
Well done! Clear, straight, professional explanation for anybody...

In any case, I'm now a new sub and look forward to viewing more of your content. Cheers, Dave
Great explanation about regular vs spiral bits. Makes me wonder where was I when you started youtube channel. Totally awesome!!!
Thank you thank you thank you! This is a incredible explanation of differences as well as the applications of the bits. I've recently been trying different routing techniques with my Dremel 4000 that I got for Christmas. It included a spiral bit that I wasn't exactly sure how to use.
Outstanding explanation. This just sold me on spending a little more on spiral bits.
Good on yer, mate! I had the idea, but still enjoyed your very comprehensive yet clear video! Greetings from the other side of the world - Norway.
This is in my opinion the best router video on TH-cam 😉 appreciate the effort
Glad you liked it!
Thanks a lot for explaining all this things
Saving to watch later. Well done

Great video, thanks for clearing up the mystery for me involving spiral bits. Now I'm eager to give it a go.
You're welcome! Let us know how you go!
Best explanation ever. Thanks
Glad it was helpful!
Awesome! Very concise explanation, already has me wondering what projects I might use them on. Thanks heaps - just shows your never too old to learn, there's always something new in wood working! I guess maybe I should go visit a Timbecon store for a look see.
Cheers
Excellent explanation! Thanks!
Excellent description of the different types of bits!
Thanks Oliver!
Those bits look great for solid surface work, thanks for this vid.
Thanks for your kind comment, Ricki. You are very welcome! Keep an eye on this channel. Our Router Bits episodes are filled with some great tips and setup hints for working with your router.
Excellent explanation. Subscribed.
Thanks so much for the in-depth review. Very well explained and presented. 👍
Thanks Glen. We hope you continue to enjoy our channel!
Thank you!! Excellent video and understanding the dynamics of the cuts was very helpful.
Excellent video, thank you
Very clear and good information!
Thanks Yangk00! Glad you enjoyed it.
Really useful information, thank you!
Excellent review! Very helpful!
Great video, perfect explanation. I was about to make a huge mistake on my bookshelf speakers project. I need to cut a 1/2" rabbet all the way around my birdseye maple veneered speakers to frame them with strips of bubinga that will get chamfered at a 45° angle. I had planned on using a standard 1/2" rabbeting bit but now I think that would have had some major tearout. Watched this video and now I think I'd be best off using an edge guide with a spiral downcut bit
Thanks for the explanation. Very helpful. Well executed video.
Excellent explanation! Thanks
Thanks, I'll definitely use the spiral bits you've recommended.
Thanks JL! Let us know how you go!
excellent presentation. thanks.
Great info - just what I was looking for. Thanks!
Thanks Darragh. We are glad you enjoyed it. There are hundreds more on this channel so feel free to check them out! Thanks for your kind comment.
Great video! Very helpful.
Glad it was helpful!
Explicación muy clara, gracias!
I am new to using a router and almost bought some standard straight bits. After watching one of the best how to video I will skip the standard straight bits and learn with the Spiral Bits. Up and down ones.
Thank you so much. I am 58 years old and want to get my wood working shop set up for my retirement.
Thanks for your kind comments John. We wish you every success in setting up your workshop!
Great job explaining everything thank you very much
Glad it was helpful!
WOW, put this video in my favorites for future references. Great job
Thank you Ted. We are very glad you have benefited from this video. If you are an avid router user, feel free to browse our The Router Bits playlist. There will be much more there for you to enjoy. Thanks again!
@@timbeconaus At my age, the router fun has opened a new world. It's amazing to me how people have figured all these thing out, and wonder what did they do way back when, before all the technology. You've really helped.
Great video...well explained.
thanks this was a great summery of the router bits I'm trying to use.
Thanks for a very interesting video about these revolutionary router bits.
Correctly though, (regardless of what the manufacturer calls them) these are helical bits.
A "spiral" has a varying radius, like a Nautilus shell. A "helix" has a constant radius, like these bits and a strand of DNA.
Interesting that the engineering guys call these helical cutters for their milling machines, not spiral cutters.
Thank you so much. Very helpful!!!
Very good information mate I understand a lot better now ,old jimmy WA
Thanks Jimmy! We are glad you enjoyed it. There are plenty more where that came from and plenty more to come. Be sure to subscribe!
great to see an Australian video All the best
Thank you for the explanation. Subscribed!
You have done a great job of explaining the how a spiral cutter works, I have been using these for years in CNC routers and on the bench in a hand tool . They are great to use ..
Just one point I want to add is that there is a dual cut version these which cut both ways at the same time giving a superb cut on both sides of the work piece., and awesome at face groves. And rebates ,
Some limitations are the up cut section is about 10 mm .
In the UK they are know as F max but just look for a combination spiral cutter .
You will love them .
Hi Robert,
We just released our range of compression bits this month - check them out! th-cam.com/video/Z11csT4_8pM/w-d-xo.html
very informative. Thank you
You got it right sir, that's why there is a need to have the guide to maintain constant and straight cut, more advantage is those bits with guide bearing, it maintain consistent constant contact with the edge of the wood.. nice tutorial video.
Good vid, very informative - I'm sold! The background music is a little distracting though. Thanks for that mate!
Clear and precise. Subscribed.
Thanks Tom! We hope you enjoy the hundreds of videos on our channel. They vary from the clear and precise to the slightly whacky, but they are all about the woodworking. Its great to have you on board!
Timbecon

@@timbeconaus I will! Greatings from Canada.
Excellent
Thanks for the informative tutorial!
You're welcome Scott. Thanks for your kind comment. We also have two more videos on our channel that deal with compression and spiral bits if you need more information.
Excellent! Thanks for taking your time. I just can't understand these thumbs down (ungrateful people).
Thanks. that was really helpful
Really helpful, thank you!
Thanks for your kind comment Bruce. We are glad we could help! 👍😀
Yes ! Thank you !
thanks - really helpful info
Thanks Graham. We are glad you enjoyed it.
I enjoyed your video. It was very helpful. Very much appreciated! Thank you!
Very nice explane of these bits, i Will notice your bit information . Some month ago I was lucky to buy an Old Stanley router with an attachment plane. There was also a Spiral bit for this beautiful plane , approx. 2,5 inch long, It gives a very beautiful cut and that with a bit produced in 1965! If you want I Will give you a picture of my treasure. Greetings from Holland and thanks for your informations, Jan
Thank you man 🤘
A very good vid with a proper explanation of these bits. Its just a pity Timercon don't ship outside AU....
Thank you for a very informative video. I found the continuous background ‘music’ highly annoying and distracting but that’s probably just me. Keep up the great work, I will definitely be back for more.
Top Job video!!
You are a real expert. pHantastic information. Where in GERMANY can I buy this? Keep going You have my subscription!
Thank you Diybert! We do not ship to Germany, but no doubt there will be woodworking retailers there who will stock and sell Spiral Router Bits. Thank you for your subscription. We hope you enjoy the entire The Router Bits Playlist and the hundreds of other woodworking videos on our channel.
Great explanation. Thanks. I have an off-topic question...at 11:59, what is the circle cutting attachment that you are using and is it specific to the router in use?
Nice video. Thnx!
You are very welcome, Joanna! Thanks for your kind comment. We have a lot of helpful videos for woodworkers on this channel so we hope you have subscribed. There are many more to come!
There's some detailed info to think about. I will now put out the money for a spiral.
Started taking notes halfway thru when I realized I'm never going to remember this stuff
Thanks
Great video, thank you for doing it. I was wondering if a 3 flute spiral bit better than a 2 flute spiral bit for cutting hard dense wood? I am working with Swartzia leiocalycina and its an insanely dense wood. It's, also very expensive. I tried a standard straight bit on a scrap piece and it kept tearing out. I then did some research and came across this video, but now I am trying to figure out if I should buy a 2 or 3 flute bit. I don't have a lot of funds atm so I can only get one bit. Any help that you can offer would be most appreciated
what if you need a bearing on the bottom instead of the top, does the smooth round part past the blade on the bottom serve as a bearing guide for a flush trim?
This was fantastic and just having experience tear out on some really nice ambrosia maple yesterday, i am grateful for the knowledge.
Are the torquata bits available in the usa?
Thanks again - excellent stuff!!👍👍🦧
Unfortunately Torquata bits are currently not available in the US. We are hoping to reopen international shipping to the US soon.
Great video. Is there a recommended rpm for these bits? I was using a 1/4 inch up spiral bit for making box joints, and I smoked a brand new Rockler bit. I’m assuming I had the rpm too high. My P.C. router was at 16, 000 rpm. Seemed to go better when I dropped it to the lowest setting 10,000 rpm. Curious if anyone has an answer
Good, fairly complete and very informative video. I might also have included that compression cut bits exist (combined upcut/downcut) and maybe something about roughing/finishing bits as well as bits with chipbreaker profiles. Still good though.
Thanks Whatevil! We always appreciate that kind of input. We felt that the video was long enough already, but there is certainly room for another to be made along the lines you suggest.
Thanks for your kind comments. Stay tuned!
Excellent presentation. One question: why would anyone still use an old-school straight bit? Is it just a matter of cost? Or do straight bits excel at something the spiral bits don’t?
Can you do a video review on the bluetooth blade fitted to the droppy in the background :)
What would be the best bit for cutting circles out of 3/8 thick plywood?
This is a superb explanation of the subject! I wish I had seen this when I started getting into CNC. It would have made the learning process much easier. This reminds me of a question I have. In cutting through vinyl paint masking, I've found that when possible, using a downcut spiral cuts the vinyl mask off much cleaner. But most of my work requires Vbits to be used. Does anyone make a downcut Vbit? Thanks.
Thanks Jim. We are glad to have been of such assistance to you!
What kind of spiral bit would you use for acrylic or plastic, up or down?
brilliant
Thanks Paul!
hi
Im looking to make a mft style bench top using jig with guide bush. what 20mm bit would you suggest for making the holes.
thanks
