The Amana Tools 316026 Carbide Tipped 2 Flute RH Rotation Bit is an 8 mm Domino joiner cutter made for Festool Domino machines, specifically the DF500. This is a router bit designed for routing slots for loose-tenon joinery in solid wood and wood composites. Model Number 316026 gives you an 8 mm cutting diameter, 28 mm cutting height, and 49 mm overall length for users who need a direct replacement bit that cuts clean and stays consistent.

What matters here is not just the size, but what that size does on the job. An 8 mm diameter bit is commonly used when you need a larger Domino mortise than smaller joinery setups can provide, and the 28 mm cutting height gives the cutter enough reach for the slot depth this class of joiner is built around. In practical terms, this helps you cut repeatable mortises for furniture parts, cabinet components, casework, and trim assemblies without fighting a dull or undersized cutter.

The cutting end uses a carbide-tipped 2-flute design. That combination is a good fit for wood joinery because it balances edge life with clean slot formation. Carbide holds up better over repeated cuts in hardwood, plywood, and other wood composites, while the two-flute layout helps the bit clear material efficiently. If you use your Domino joiner regularly, that means less variation from mortise to mortise and fewer headaches when fitting tenons.

This bit uses right-hand rotation and an inside shank thread of M6 x 0.75. Those details matter because replacement joiner bits are not universal just because the diameter matches. The mounting and machine fit have to line up too. For owners of the Festool Domino DF500, this is the kind of spec you need to verify before buying, and Amana gives you the exact thread and machine callout so you are not guessing.

At 49 mm overall length, the bit is compact enough for the intended machine platform while still providing the cutting length needed for accurate slot routing. The build is straightforward and job-focused: no gimmicks, just the dimensions and cutting geometry required for clean mortises. For anyone doing repeat joinery work, that kind of predictability is the whole point. A Domino joiner is only as accurate as the cutter you put in it.

This Amana replacement bit is best suited for woodworkers, cabinet installers, trim carpenters, furniture builders, and serious DIY users already working in the Festool Domino system. If you own a DF500 and need an 8 mm replacement cutter for precise slot cutting in wood, this is the right type of accessory. If you do not have a compatible Festool Domino joiner, the size alone does not make it a fit, so compatibility is the first thing to check.
