Key Features
Carbide Cutting EdgeThe carbide-tipped cutter is built for long service life, with Festool stating it can handle roughly 5,000 to 14,000 joints depending on the material. That matters if you are cutting repeated mortises and do not want edge wear to show up in your fit. Clean Mortise WallsSpiral flutes help clear chips and keep the cut tracking cleanly. The result is a more consistent mortise for 10 mm DOMINO tenons and less cleanup before glue-up. Made for DF 500This Festool 493493 Domino DF 500 Cutter, 10mm is sized specifically for the Festool DF 500 joining machine and 10 mm tenons. The internally threaded design makes bit changes straightforward when you are switching joinery sizes.
Overview
The Festool 493493 Domino DF 500 Cutter, 10mm is a carbide-tipped DOMINO cutter accessory for the Festool DF 500 joining machine. This is a joiner accessory designed for cutting 10 mm mortises for loose tenon joinery in wood. Model Number: 493493. If you are using 10 mm DOMINO tenons and want the mortise size to match the tenon correctly, this is the cutter that does that job.
What makes this cutter worth paying attention to is not just the diameter, but how it performs in actual joinery work. Festool lists a 10 mm cutting diameter and a 28 mm cutter length, which is the size combination intended for 10 mm DOMINO tenons in the DF 500 platform. That means you are not guessing at fit or trying to make another cutter work for a tenon size it was not designed around. For cabinet work, furniture building, and general woodworking joinery, proper mortise sizing is what keeps parts aligned and glue joints predictable.
The carbide-tipped construction is the big practical advantage here. Festool states the bit can withstand about 5,000 to 14,000 joints depending on the material being cut. In plain terms, that means this is built for repeat work, not just a few test mortises on a weekend project. If you move between softer sheet goods and denser hardwoods, cutter life will vary, but the basic point stands: this is a production-grade cutter, not a throwaway accessory.
Festool also uses spiral flutes on this DOMINO cutter, and that matters because cleaner chip evacuation usually means cleaner mortise walls and more consistent plunge performance. On the bench, that shows up as cleaner joinery, more reliable tenon fit, and less time fussing with loose fibers before assembly. For anyone doing visible furniture joinery or repeat panel alignment, clean mortises are not cosmetic trivia. They save time and reduce rework.
From a design standpoint, the internally threaded body is another practical detail. Bit changes are quicker and simpler, which is useful if you regularly swap between different DOMINO sizes on the same job. That is the kind of small feature that does not sound exciting until you are in the middle of a build and trying to keep workflow moving. The light 0.1 lb weight also means it is a compact accessory that does not add bulk to your kit.
Compatibility is straightforward. This cutter is suitable for the Festool DF 500 and is intended to create the proper mortise width for Festool 10 mm tenons. It is not a general-purpose router bit and it is not presented here as a fit for other machines. If your workflow is built around the DF 500 joining system, this is the correct cutter for 10 mm DOMINO joinery.
Who should buy it? Woodworkers, cabinet installers, furniture makers, and finish carpenters already using the DF 500. If you own that machine and need to cut for 10 mm tenons, this is the right accessory. If you do not own a Festool DF 500, this cutter is not the place to start. It is a purpose-built accessory for one system, and that is exactly why it works well.

Pro Tip
On the DF 500, keep your cutter size and tenon size matched every time. If you are switching up from smaller DOMINO sizes to this 10 mm cutter for heavier joinery, double-check your machine settings before the first plunge so your mortise depth and stock layout stay on track.
