The Festool 493492 Domino DF 500 Cutter, 8mm is a replacement DOMINO cutter made for the Festool DF 500 joining system. This is a joiner accessory designed for cutting clean 8 mm mortises in wood for DOMINO joinery. Model Number: 493492. If you are building cabinets, furniture, face frames, or general wood assemblies with 8 mm DOMINO tenons, this is the cutter that matches that workflow.

What matters here is not just the diameter, but what that diameter does on the job. The 8 mm cutter creates the proper mortise width for Festool 8 mm tenons, which means less trial-and-error during fit-up and more predictable joint alignment. When a cutter is matched correctly to the tenon system, you get tighter, more repeatable joinery and spend less time cleaning up loose or inconsistent fits.

The carbide-tipped construction is the big selling point for anyone who uses a DOMINO regularly. Festool rates this cutter to withstand about 5,000 to 14,000 joints depending on the material, so it is built for real production work, not just occasional hobby use. In practical terms, that means better wear resistance and longer useful life when you are cutting repeated mortises in hardwood, plywood, or other wood materials.

Spiral flutes are another detail worth paying attention to because they help produce clean cuts. On a mortising cutter, cleaner chip evacuation usually means a cleaner mortise and more consistent plunge performance. If you are doing visible joinery or you need parts to pull together square without extra persuasion, that cleaner cut quality matters.

Festool also uses an internally threaded design for quick, easy bit changes. That makes this accessory easier to swap when your work changes from one tenon size to another. For shop work and install work alike, quicker changeovers help keep the DF 500 moving instead of sitting on the bench while you wrestle with accessories.

Compatibility is simple and important: this cutter is suitable for the Festool DOMINO DF 500 and is intended for use with 8 mm DOMINO tenons. It is not a general-purpose router bit and it is not a universal joiner accessory. It is a purpose-built DF 500 cutter for wood joinery, which is exactly why it works so well when you use it in the system it was designed for.

This cutter makes the most sense for woodworkers, cabinet installers, trim carpenters, furniture builders, and serious DIY users already invested in the DF 500 platform. If your work regularly calls for strong, repeatable floating-tenon joints and you use 8 mm tenons, this is the right replacement cutter to keep on hand.
