  • Designed for Festool DF500 machines ensuring perfect fit
  • Five carbide bits from 4mm to 10mm cover all joint sizes

Domino Joinery Bit Set

This Feyzor five-piece solid carbide bit set is engineered for the Festool DF500 Domino joining machine. It supplies the cutters needed to produce precise mortises in furniture, cabinetry and general wood assemblies. Woodworkers who require a full range of standard diameters in one package will find the set matches that requirement. It is not intended for machines that accept a different shank or cutter geometry.

Cutting Performance

The two-flute spiral design with sharp edges removes material cleanly across various wood types and thicknesses. Solid carbide construction combined with a black PTFE coating reduces friction and resists wear during extended cutting sessions. The complete set weighs only .09 pounds, so the added mass on the machine spindle is minimal. No thermal, noise or power-draw data is provided for these cutters.

Included Accessories

The bits are housed in a compact case measuring 4.84 inches high, 4.05 inches wide and .9 inches long for organised storage and transport. Diameters covered are 4 mm (.16"), 5 mm (.2"), 6 mm (15/64"), 8 mm (5/16") and 10 mm (25/64"). No additional software, lubricants or mounting hardware are mentioned in the supplied information.

Questions about this item

How do I install the 4mm solid carbide bit in my Festool DF500 Domino joining machine, and what step is often missed?

Insert the bit into the DF500 chuck until it seats fully, then tighten the locking screw securely; the step often missed is verifying the bit sits flush against the internal stop so the cutting depth stays accurate.

What maintenance or replacement will the PTFE-coated carbide bits need over time?

The black PTFE coating reduces friction and resists pitch buildup; wipe bits clean after each use and resharpen or replace when the two spiral cutting edges dull enough to leave tear-out in mortises.

What limit appears first during sustained mortising with the 10mm bit in dense hardwood?

Heat buildup at the cutting edges is the first limit; the solid carbide and PTFE coating delay it, but continuous deep cuts in dense stock will eventually soften the coating and dull the flutes.
