- Wood Router Bit come in many shapes and sizes and some can be confusing like the Upcut Spiral Router bit or the Downcut Spiral bit because depending on where you use them, in a hand-held wood router, a CNC machine, or in a wood router table, they give the illusion of cutting differently, then if you add the wood routing bit the Compression Router bit or even the Down Spiral Fine Edge bit, now you can have even more different routing jobs so understanding how they work is crucial.
So, in this video, I'll be showing you some router bits for beginners.
Remember that these spiral router bits can be used as CNC router bits, as the two are the same.

You're such a great person... when I'm missing my dad, I like to watch your channel.
I'm living in the Netherlands and I'm also watching you're tips and tricks. I like them very much. Thanks.
Well explained. Colin. You've taken the mystery out of up down bits and cutting direction. Very helpful.
SUPER useful to be able to see objective side by side results! Recently got my first router and videos like this are really helpful in bit selection
Oh no! Looks like I need some more bits then! Great video Colin.
Interesting comparison, would have been nice to see a straight bit as well
Perfectly explains why a couple of bits I have didn't perform quite how I expected. Thank you! Now I will be able to choose more carefully.
Pretty impressive results, Colin!!! 😃
Thanks a lot!
Stay safe there with your family! 🖖😊
Great explanations of the various types of bits. Information that I never knew. Thank you very much.
you said it perfectly for me. I learned something....a good day
Great explanation of how 5he spiral direction effects the quality of the cut. Makes so much sense.
Thanks for the knowledge about buying Spiral Router Bits !!!!!!!!!!!!!!!!!!
Good stuff!
I know there have probably been countless spiral-vs-straight comparisons, but including a straight bit for comparison would have been useful.
Another great video from Colin. I had no idea up spiral, down spiral, compression and fine router bits even existed! I learned something from Colin again. I always wanted to get a router, as they look a great machine to have, but not sure if I'd use one that much (hobbyist)
Very good explanation of the up/down spiral bits!
Interesting and informative. I'm new to using a router, so I'd never would've thought about this.
I so appreciate you taking time to explain everything! I'm new at this so your info is handy.👍
Very, very nice and useful analysis. Thank you!
Thanks Colin, nice to see an objective test.
Interesting video with very relevant information included. Many thanks.
I would have liked to see a straight bit in the comparison test. It would give me an idea if spending the extra money on these bits is worth it.
One of the biggest advantages of spiral bits over straights, is that spirals prevent kickback issues due to the slicing rather than the chipping that straights do. For plunge cuts, either would work ok, but spirals REALLY shine with edge trimming/cutting.
Wow amazing method of learning and u.r good teacher 😊👍👍👍plus amazing tools and machines
Many of the CNCs tend to make several passes, getting lower and lower until they have cut through. In the case of your compression bit, the first pass at the top of the workpiece would be an up-spiral, but that would change to a down-spiral as the passes got deeper and deeper. It would be interesting to see the results of the 4 bits with the CNC doing what you did free hand. Also, when you cut all the way through free hand, the chips could drop out the bottom which would not be the case for a workpiece on the CNC's waste board. It would be interesting to see how the bits fared on a CNC with regard to chip clearing.
Compression bits are exclusively designed to cut in one pass with the tip coming out to the other side of the board.
Thank you! excellent video. I learned about compression bits and fine finish, something I didn't know about.
Very interesting & nice demonstration Colin! 👍👍😉😉
Well done, an excellent video and period of instruction.
Handheld routers came first and somebody had the idea to mount them upside down in a router table later.
So UP is toward the router, and DOWN is away from the router. That's how I remember which is which when it comes to upcut or downcut spiral bits.
I hope that helps.
Exactly. I remember it as upcut cuts towards the motor, and downcut cuts away from the motor
Very interesting information, i have a spiral bit . It was given to me, haven't used it yet.
Thank you for this information!
Good video. Perhaps a look at how a straight bit would compare?
Good morning, And what about the staight bit in comparison ? Thanks.
Pertinent and precise to the matter. Cheers.
First congratulations for the channel. I really like your videos, unfortunately I don't understand your language and there's no translation into Portuguese. But you can always learn something. 👍🏻👏🏻👏🏻👏🏻
Thanks Carl
Hi. Do you have a video that has all what we need to know about storing hard wood before using it, about grain structure, warping etc? If not, can you make such a guide video? I do not understand why woodworkers store wood a couple of months before they work it, they say it is to reach the humidity of the shop, but what about the humidity in the home of the end user? I am so confused.
Hi I make the odd sign every now and then that fine down cut bit looks like it might work pretty nice for me do you have a link or let me no where to buy one your videos are great they help out a lot keep making these videos
Very interesting video. Thanks for sharing. I've learned a lot again (at least in theory)
Learned yet again.
Thx!
Wish I'd seen this before I bought the up spiral bit days ago.
This is very helpful - thank you!
Great video thanks! Would have loved to see the same cuts on MDF too
Really great!!!!!!!!!❤❤❤❤
I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.
Great video. Thanks Collin.
Awesome educational vid. Greetings
This is pretty helpful, thanks!
Thanks for the very informative video. Because straight bits will be the easiest to sharpen, would it not be better to take most material away first with a smaller diameter straight bit and then 'sneak cut' with a spiral bit?
I assume these are more costly than straight cut bits, Colin? How do they compare and why choose a spiral?
Can one use a down spiral bit on a mortise or dado? Will the chips clear?
With a dado you want the chips to be taken out of the cut - towards the collet, so use an upcut bit.
Will a router bit of some kind plow thru 2 inches of solid dry pine in one pass?
Interesting - but they were all through cuts except the pine at the end. Bit performance in a through cut does show the bit's true advantages.. Only dadoes (or housings in other places) need to ignore the spiral bits' actions because all gets confused when not penetrating the wood.
Thanks for sharing that, well said!
Can you link where to buy the down spiral fine cut bit please.
Colin I’m trying to make wooden wheels with spokes I have used bandsaw and and jigsaw and not very good at cutting
I want to use my m18 compact router and I’m going to make a jig out of acrylics what’s the best bit should I use with my router
Question for the expert (you): Would I be able to use my 1/8" shank Dremel bits, with a 1/4"-1/8" adapter, to use with my DeWALT DWP611 palm router?
Please advise, thanks.
I'll get a compression bit for melamine. I need a perfect nice and clean cut
Good comparison thanks
Good stuff
Thanks for the video.
I'd never heard of that "compression" bit before. Am I the only one who thinks that's an odd name? Did you use the same router and router speed for this demo? Thanks for a fine video!
I think it's a good name. Just hearing the name for the first time now, and I knew immediately that it would have opposing spirals "towards" each other and not away.
Seems like it's named well if you can guess it's geometry instantly from the name alone.
very nice
Can those bits be used to cut a compass for making circles ? Also what’s the difference between a plunge router and a compact one other than size ? I feel like a router does more and is less intimidating than a jigsaw. I want to start learning to use these tools for making my own art substrates.
Thank you!
As always a lot of practical information LOVE IT! but.....random question Colin, which came first the up or the down? seems like the compression bit would be suited to the CNC where you could really dial it in
They are. Used mostly for cutting double sided melamine. Lots of closest companys use them for cutting panels and shelving. Has to set up so it is just below the board. They can be sharpened three times. Solid carbide. I worked at a company that made and sharpened them.
Thanks 🙏
Thanks
Bravo.
Thanks for the video, one question, from your comparisons it looks like we never want to use an up spiral bit, it's obviously not the case since they exist, so in what situations we do want to use them? are they easier to cut? they produce less heat? they are cheaper? why and when should we use them?
Up is good for a router table since it will pull the work piece 'up' towards the router motor. On a non through cut it also cuts faster since it pulls the chips out of a tenon/groove/dado. So you can use it in situations like this where the tear out, if any, will not be noticable.
I use Whiteside bits and I do not think the price differs for up vs down.
@@mm-nyc I see, thank you for the explanation.
JAN APIK KANG 👍👍👍
👍👍👍👍
Thank you for the informative and practical video.
I know the manufacturers call these "spiral" bits. The correct name for this geometry is helix because the radius is the same along the rotation axis. In a spiral the radius increases or decreases.
DNA is in a helix, and an old style wood screw is a spiral.
Circular staircases are usually helical, like inside a cylinder. If they climb inside a cone, they will be spiral.
thanks
first one ☝️
I recently used a spiral upcut bit while cutting exact fit dadoes in 3/4 inch plywood. While cutting one of the dadoes the router began laboring so I stopped cutting. Unfortunately the bit had loosened in the collet and started "drilling" deeper into the wood and penetrated through the bottom surface. Moral - tighten those bits!
Terry, I've had exactly the same when I used an upcut bit for the first time recently (in a box-joint jig I'd just made). The spiral is trying to drag the bit out of the collet and as you say, these bits need to be tightened more than "standard" bits.
@@helmshardover all router bits should be held securely. But if you top load bits (flip a router over) and just let them fall to the bottom of collets you're going to have a problem getting collets tight on bits. To understand why you have to imagine how the whole mechanism works. The nut driving the collet down into the shaft taper and the jaws of the collet grabbing the bit shank. When the bit can't move with the collet you're baked. Then you have to overcome the friction between the bit shank and the collet jaws to get the collet any tighter. Which you can do as you pop a blood vessel in the process. It is easier to just make sure the bit shank doesn't bottom out though. To that end I ball up a little bit of paper towel and stuff it into my router collets. Paper easily compresses yet holds bits up while they are waiting to be tightened. Problem solved.
@@1pcfred "all router bits should be held securely" - of course.
I've been using Routers & Router tables for over 20 years, and never had a bit come loose till this one.
It's a warning to anyone that what you perceive might be tight may be tested with an upcut bit, so give it more!
@@helmshardover in the past decades things have been changing. Now there's imported tools. Which has implications for Americans. Because foreigners don't really use our measuring system. They still like our money though. So I seen them selling 6 mm shank tools as 1/4" Now you can load a 6 mm bit into a 1/4" collet and it seems to hold. Up until you start running it anyways. Then it might slip some. Really if you want hold you want 1/2" shank bits. It's all about the surface area. 1/2" router bits are the luxury ride. They cost more because they're worth it.
Excellent Comparison, and very clearly explained. Thank you for sharing your experience.
Upcut spiral bit is EASILY the fastest making grooves and heats up the least, since it clears the chips up away from the groove. Always use it for the first cut. And, it is as good in through cuts as a downcut or up/down bit.
I can only assume the compression bit was designed in the 60s...
why do all guys with toy routers talk about bits they no nothing about . Chip-lode is what you need to learn before you ever buy a bit. Every bit and the proper Speed ,Feed and RPM and not once did you talked or say anything about Chip-Lode.
Great video. Thanks, Colin. You really do some great work. I appreciate how you share your knowledge.
Just got myself an upcut and snapped it in the first second,,, on Acrylic sheet,, am I missing something. How strong are these compared to the straight edge equivalent?
Great information!!
Once you mount that router in a table you have to reverse your thinking. Now a down cut spiral bit cuts up from the bottom.
Can you provide a link to the freud down spiral fine finish bit please. Thank you
you didn't explain how easy the bits went through the wood
you need to learn about Chip lode before you do anymore video on router bits
With a last name like that you must be Dutch
Great video. Thanks
What to do when a Bit gets dull
Really enjoy this channel
9:00 such cute whales :)
Colin, you have inspired me to do some testing as well. My testing will be around the CNC engraving that I do a lot. Currently, I don't use many spiral bits; mine are all the two flute straight bits. What I've heard is that if I'm hogging a lot of material out each pass, that a downcut spiral will have a tendancy to clog the routed pockets, even though the top edges are clean as you showed in this video. Depending on the type of wood (e.g., cedar), that clogging of sawdust in the routed channels could be a problem, whereas an upcut spiral bit won't have the clogging but the top edges won't be as clean. When you've used downcut spiral bits on your CNC router, have you ever had any problems with sawdust clogging as I've described? Just curious...
Using a down spiral in a CNC, like my Shark HD520, definitely forces the debris into the cut. This is usually the biggest issue when first starting a cut because the chips have no where to go. To help with this, add a ramp to your tool path so the bit doesn't plunge straight into the material and then start cutting. Also, you may need to adjust your spindle/router speed and your feed rate to get good chip size and evacuation. If you are not using some dust collection, adding some will help clear chips off the work surface so it is not driven back into the pocket. Hope this helps but I think in 2 years you may have figured this out on your own.
What is a fishtail bit?
Thanks.
Nice video with simple, but
illustrative explanation. Thanks Colin.
Super informative and helpful, thank you Colin!
Great Video!!! Thank You For The Info!!! 👍😎
Excellent information. Thank you.
Thanks for the explanation all new to me. Very informative
Great video: just what I wanted to know. I'm now going to try a compression bit.
Great video, does the article cover the cost to performance analysis? I'd like to see that. Do I just reverse some of these results if it's a router being used in table?
