The Amana Tools 316020 Carbide Tipped 2 Flute RH Rotation Bit for Festool Domino Joiner is a replacement joiner bit made for routing Domino slots in solid wood and wood composites. This is a joiner bit designed for loose tenon slot cutting on the Festool Domino DF 500 system. Model Number 316020. If you rely on your Domino for clean, repeatable joinery, this bit is the working end that directly affects fit, finish, and cut quality.

This bit uses a 4 mm cutting diameter with an 11 mm cutting height and a 38 mm overall length. In real use, that smaller diameter makes it a practical choice for lighter joinery tasks, narrower stock, and applications where you do not want to remove more material than necessary. The 2-flute cutting geometry helps evacuate waste while keeping the cut controlled, which is what you want when cutting precise mortises for Domino tenons.

Amana specifies this as a carbide tipped, right-hand rotation bit for Domino machines. The big advantage here is durability at the cutting edge paired with a format made specifically for the machine instead of adapting a general-purpose cutter. On joinery work, that translates into more predictable slot geometry and less hassle when you are lining up parts for glue-up.

The M6 x 0.75 inside shank thread is a key spec, not a throwaway detail. It means this is built to mount correctly on the Festool DF 500 platform. For anyone replacing a worn cutter, that thread spec is what keeps you from ordering the wrong bit and losing time on the bench.

Application-wise, this bit is intended for routing slots in solid wood and wood composites. That makes it a fit for cabinet parts, face frames, furniture components, trim assemblies, and other woodworking jobs where Domino joinery speeds up alignment and assembly. It is not about flashy features. It is about getting back to accurate mortising with the machine the bit was made for.

If you own a Festool Domino DF 500 and need the correct 4 mm replacement cutter, this is the kind of part worth buying right the first time. It is best suited to woodworkers, cabinet installers, trim carpenters, and serious DIY users who already understand the value of tight-fitting loose tenon joinery and want a bit that matches the machine and the job.
