CMT 380.060.11 Solid Carbide Bit for Domino Jointing Machines by Festool DF500 is a replacement domino joinery cutter built for loose-tenon slot routing in wood. This is a domino jointing machine bit designed for cutting 6 millimeter mortises in solid wood and wood composites. Model Number: 380.060.11. If you are running a Festool DF500 and need the correct cutter for 6 millimeter domino work, this is the bit that matches that job.

The key numbers here are straightforward and useful. You get a 6 millimeter cutting diameter, a 28 millimeter cutting length, and a 49 millimeter overall length. In practical terms, that means this bit is sized for precise, repeatable mortises rather than broad material removal. The 2 cutting edges and 2 spiral flutes are there to keep the cut efficient and the slot geometry consistent, which is exactly what matters when joinery fit decides whether an assembly goes together cleanly or turns into sanding and shimming.

CMT calls out a premium steel body with a solid carbide spiral portion and center point. That combination matters because the body needs to stay stable in the machine while the carbide does the real cutting work. The center point helps the bit start where it should, and the spiral design is meant to clear material while maintaining the shape of the mortise. For woodworkers doing face frames, cabinet parts, furniture components, or panel assemblies, that kind of controlled cut is the whole point.

This bit also uses a black PTFE coating. On a tool like this, that is not window dressing. A coated surface can help reduce buildup and friction during repeated cuts, especially when you are working through sheet goods or composite materials that tend to leave residue behind. Less buildup on the bit usually means more predictable cutting and less time stopping to clean tooling.

Compatibility is an important part of this product. The source data specifically identifies this bit for use on Domino machines and calls out the Festool DF500. It also lists an M6 x 0.75 millimeter shank specification. That makes this a purpose-built replacement cutter, not a general router bit you would drop into any router collet. If you need a cutter for a DF500 to route 6 millimeter domino slots, this is the application it is intended for.

Who should buy it? Woodworkers, cabinet installers, trim carpenters, and furniture builders who already own or use a Festool DF500 and want a dedicated 6 millimeter replacement bit. If your work depends on strong, repeatable loose-tenon joinery in hardwood, softwood, or wood composites, this cutter makes sense. If you do not own a compatible domino joining machine, this is not the right tool to improvise with.

CMT 380.060.11 Solid Carbide Bit for Domino Jointing Machines is the right buy when fit matters more than hype
