The Festool 495663 Domino DF 500 Cutter, 4mm is a replacement DOMINO cutter made for the Festool DF 500 joining machine. This is a DOMINO cutter designed for cutting 4 mm mortises for loose tenon joinery in wood. Model Number: 495663. If you use the DF 500 for cabinet parts, furniture, trim assemblies, or other precise wood joinery, this is the cutter that gives you the correct mortise size for 4 mm DOMINO tenons.

What matters here is fit and repeatability. This cutter is built specifically to create the proper mortise width for Festool 4 mm tenons, so your joints line up the way they should without trial-and-error tuning. Festool also uses spiral flutes, which helps the cutter clear material cleanly and leave a consistent slot. For anyone doing face frames, light furniture parts, drawer components, or other smaller joinery work, that clean cut translates to easier assembly and less fuss during glue-up.

The cutting head is carbide tipped, which is the right move for a joiner accessory that sees repeated plunging in sheet goods and solid wood. This cutter can withstand roughly 5,000 to 14,000 joints depending on the material. That range matters because joinery accessories live or die by edge life. A cutter that stays sharp longer helps keep mortises crisp and keeps the machine from working harder than it needs to.

Festool also keeps the design practical. The cutter is internally threaded for quick changes, so swapping sizes on the DF 500 is straightforward when a project calls for different tenon dimensions. The cutting diameter is 3/16" (4 mm), and the cutting length is 7/16" (11 mm). This version is also shorter than a standard cutter and is used with the machine set to a 13/16" (20 mm) depth to create a 3/8" (10 mm) deep mortise. That makes it a purpose-built accessory, not a one-size-fits-all bit.

In real shop use, this is the kind of cutter you buy because accuracy matters more than improvising with a close-enough bit. The DF 500 system is built around matched cutters and tenons, and this accessory keeps that system working the way it was intended. If your work depends on strong alignment, repeatable plunge cuts, and clean-fitting loose tenon joints, using the correct cutter size is not optional. It is the whole point.

The best fit for this cutter is the woodworker, cabinet installer, finish carpenter, or serious DIY user already running a Festool DF 500. It is also the right replacement if your original 4 mm cutter is worn out and you want to restore cut quality instead of fighting burn marks, rough mortises, or loose-fitting joints. If you do not own a DF 500, this is not a general-purpose router bit. It is a dedicated joinery accessory for that machine and for 4 mm DOMINO tenons.
