Product Description
CMT Router Bit for Domino XL Joining - 12mm RH by CMT is a precision spiral router bit engineered specifically for use with the Festool DF700 Domino joinery machine. Designed to rout clean, accurate mortise slots in solid wood and wood composite panels, this 12mm right-hand bit delivers the tight tolerances required for strong, reliable Domino loose tenon joints. Whether you are assembling furniture, joining cabinet face frames, or building custom millwork, this bit provides consistent results across a wide range of wood-based materials. The combination of an extra-fine micrograin carbide spiral portion and a black PTFE non-stick coating makes it a dependable choice for professional woodworkers who demand precision and tool longevity from every cut.
Key Features
- Extra-fine micrograin carbide spiral portion - delivers superior edge retention and cleaner slot walls compared to standard carbide grades, reducing tearout in both solid hardwood and wood composites.
- Black PTFE coating on the spiral portion - prevents pitch, resin, and glue buildup during cutting, keeping the bit running smoothly for longer between cleanings and reducing friction heat in the cut.
- Premium quality super-strength steel body - provides the rigidity needed to maintain accurate 12mm slot dimensions cut after cut, even in dense hardwoods.
- 2 cutting edges (Z2) with 2 spiral flutes - balanced geometry promotes efficient chip evacuation and smooth plunge action, resulting in flat-bottom mortise slots with minimal resistance.
- M8x1mm shank - matches the proprietary spindle thread of the Festool DF700 directly, ensuring a secure, wobble-free fit without adapters.
- 12mm cutting diameter with 70mm cutting height - produces the full-depth mortise slots required for Domino XL loose tenon joinery in thick stock and wide panel edges.
- Right-hand (RH) rotation - optimized for the standard forward cutting direction of the Festool DF700, making it a direct, ready-to-install replacement or upgrade bit.
Why This Product
- Purpose-built for the Festool DF700 - the M8x1mm shank threads directly into the DF700 spindle, so there is no guesswork about fitment. This bit is specified for that machine and works without modification.
- PTFE spiral coating extends usable tool life - by actively resisting resin and glue adhesion during slot routing, the coating keeps cutting performance consistent across long production runs, reducing the need to stop and clean the bit mid-task.
- Handles both solid wood and wood composites - the extra-fine micrograin carbide is suited to the abrasive nature of MDF, chipboard, and plywood as well as the varying grain densities of solid hardwoods, giving this bit broad application coverage from a single tool.
- 70mm cutting height in a 90mm total length - the geometry maximizes the usable cutting zone within the DF700 stroke range, making it effective for deep mortise slots needed in thick workpieces typical of Domino XL joinery applications.

Frequently Asked Questions
Is this bit compatible with the Festool DF500 as well as the DF700?
According to the product data, this bit is specified for the Festool DF700 only. The DF500 uses a different shank system, so this 12mm bit with an M8x1mm shank is intended for DF700 use.
What materials can this router bit cut?
This bit is designed to rout slots in solid wood and wood composites, including materials such as hardwood, softwood, MDF, chipboard, and plywood. The extra-fine micrograin carbide spiral handles both the natural grain of solid woods and the abrasive content of engineered wood products.
Why does this bit have a PTFE coating on the spiral portion?
The black PTFE coating on the spiral portion resists the buildup of pitch, resin, and glue that commonly accumulates during slot routing. This keeps the cutting flutes clear during use, reduces friction, and helps maintain consistent cutting performance over the life of the bit.
What does "RH" rotation mean for this bit?
RH stands for right-hand rotation, meaning the bit is designed to spin in a clockwise direction when viewed from the shank end. This matches the standard spindle rotation direction of the Festool DF700 Domino joinery machine for which this bit is intended.
