Domino Tenons Router Bits for DF500

[Size: 8mm, Size: 8mm]
This is very high quality. I’ve used it to shape several dominos now and there’s absolutely no indication of wear on the cutting edge. My only complaint has nothing to do with the quality of the bit, but rather with the product page. I should’ve been more observant, but I didn’t realize this was an 8mm domino cutter until after it arrived. I use 5mm much more often and wish I’d gotten the smaller size, if available, but this is still highly useful. I can make dozens of these dominos in an hour, saving a ton of money that would otherwise have gone straight to buying them. And I can make them out of whatever wood species I prefer for that project, creating a stronger joint overall.I highly recommend this bit.

An excellent quality router bit. Please excuse my rough freehanding demonstration involving a drill press. Note just how this sharp bit was able to carve out this weathered yellow cedar so accurately and without tearing, leaving just a 1 mm thick shelf at the bottom lip. Wood sample in photo is 11/16" thick.My goodness! If you need a router bit with this profile and size, you just may be satisfied with this one.

This router bit feels well made and produced clean, consistent cuts in my router table. It stayed sharp throughout my project, and I didn't notice any burning or rough edges when used at the proper speed. The 1/2" shank feels solid with very little vibration, and it worked well for making floating tenons. If you already have the right setup for this type of joinery, it's a good quality bit that does exactly what it's designed to do. Easy to use. A little pricey, but works well enough to justify the cost.

This router bit cuts a fluted profile for making your own Domino-style loose tenons from scrap wood, The 1/2-inch shank and larger router runs smoothly. The cutting edges are sharp and produce nice clean cuts with the flutes that make using the finished domino joining easy, when gluing up. allowing glue to fill the flutes. Solid carbide, so it should last a good long time.This bit is strictly a single-purpose bit for creating dominos and I would sneak up on the final size as you are cutting for width. Once your stock is cut to the general right size, running it against this bit goes a lot quicker than you would think. Pretty easy to use - just test your setup stick before doing a long run.There are some competitors out there, but this is a pretty good value for one router bit. The real bargain is getting the set of all 4 bits and pre-making a variety pack of loose tenons for your DF 500 well ahead of time. Oh, I've seen videos of people leaving the stock long and just cutting to length as you are doing a project? Not a fan. Tenons pre-cut to your lengths are a lot more handy and will cause you to reach for your Domino cutter more often.Recommend

I really like that this bit uses a 1/2-inch shank. I generally feel more comfortable running 1/2-inch router bits than smaller 1/4-inch shanks, especially with a specialty profile like this. The bit feels substantial in the hand, and the extra weight gives it a solid, well-made feel rather than seeming lightweight or flimsy.The cutting edges arrived very sharp, and the bit produced a clean, consistent profile without tearing up the wood. It ran smoothly and was easy to use once the router height and fence were set. The profile is straightforward to dial in, especially when using longer stock on a router table and cutting the individual pieces to length afterward.I do not own a Festool Domino machine, but I regularly cut my own mortises and make floating tenons. This bit works perfectly for that process. The fluted profile gives the tenon room for glue to move and spread instead of trapping excess glue behind a tight-fitting piece. That can help reduce the hydraulic pressure that sometimes occurs when driving plain square tenon stock into a snug mortise.The bit is also more versatile than just making loose tenons. The shaped profile could be used to add decorative details to trim, small moldings, furniture components, or exposed edges. That gives it additional value as a specialty profiling bit rather than limiting it to one specific joinery task.Overall, I am very impressed with the quality. It is sharp, stable, easy to use, and cuts cleanly. Between making custom loose tenons and creating decorative profiles, it is a versatile bit and a very good value.

Looks like a nice bit for the price. I wasn’t paying attention and thought it would fit my CNC machine 1/4” shank but it’s a large 1/2” shank. I’m sure I’ll eventually find something to use it on. Looks like it will do a great job though.

Full transparency: I do not own a Festool Domino. I usually cut my own mortises with a router and straight spiral bit, then use square stock cut down to size for loose/floating tenons. That method works fine, but one downside is that plain square stock does not leave much room for glue squeeze-out and I have cracked work pieces before with hydraulic pressure when hammering in a snug floating tenon. That is where a bit like this is really useful.This router bit cuts a Domino-style fluted profile into your tenon stock, giving the tenon that fluted shape that helps with glue distribution and fit. I do not have actual Festool-branded Dominos on hand to compare side by side, but based on the ones I have seen before, the profile this bit creates looks very close to the real thing.I tested it on some scraps of quarter-sawn white oak, and the results were excellent. The profile came out clean and consistent, and the finished pieces looked like proper Domino-style floating tenons. My scraps were a little short, so they were harder to control safely and smoothly across the router table. For future use, I’ll definitely use longer stock, cut the profile first, and then cut the individual tenons to length afterward.The bit itself feels very well made. The 1/2-inch shank is solid and heavy-duty, the carbide looks clean and substantial, and I did not notice any visible defects in the finish or cutting edges. I ran it in my router table at around 20,000 RPM and did not notice wobble, runout, or any sketchy behavior. It cut smoothly and left a clean shape. No burning whatsoever. I’ve only made a few test cuts so far, so I’ll keep an eye on long-term durability, but first impressions are very good. The carbide feels thick, the bit feels strong, and the cut quality was exactly what I hoped for.If you own a Festool Domino and go through a lot of tenons, a bit like this could pay for itself pretty quickly. Factory Dominos are not cheap, and this lets you turn scrap hardwood into useful floating tenon stock instead of throwing it away. Even without owning a Domino machine, this is handy for anyone making router-cut mortises and wanting better loose-tenon stock than plain square strips.Overall, this is a high-quality router bit that cuts a clean, accurate Domino-style profile and makes excellent use of scrap wood. Five stars.

I got this router bit in the 10mm size hoping to use it to make some Dominos in dimensions not available from Festool. I haven't had tun a test with it yet, but examining the profile of the cutters, it doesn't conform that well to an actual 10mm Festool Domino. Festool 10mm Dominos have a thin vane (3/32") running the length of each side of the Domino. The help center the Domino and can deform of the two pieces of wood being joined were slightly off when the mortises were cut. Unfortunately, on the 10mm bit I received, the vane is about 1/8" thick and and considerably deeper. This will likely still produce a useable Domino, but not one with the profile Festool designed
