CMT 380.141.11 Bit for Domino Jointing Machines by Festool DF700, 14mm 9/16-Inch, M8x1 Shank is a replacement Domino cutter made for cutting 14 mm mortises on the Festool DF700 platform. This is a router bit designed for loose tenon joinery in solid wood and wood composites. Model Number: 380.141.11. If you are using a Domino XL for larger joinery work, this is the bit that sets the mortise size and directly affects fit, cut quality, and production speed.

The big story here is fit and application. This bit has a 14 mm cutting diameter, a 70 mm cutting length, and a 90 mm overall length, so it is aimed at the larger end of Domino joinery where strength matters more than compact size. That makes it a practical choice for furniture parts, doors, tables, frames, and other assemblies where a standard smaller cutter would not give you the same glue surface or joint size.

CMT builds this cutter from solid carbide for heavy workloads. That matters because Domino work is repetitive by nature. You are not making one cut and moving on. You are often plunging the same setup again and again across multiple parts, and a stronger cutter body helps maintain performance through that cycle. The 2 cutting edges and 2 spiral flutes are there for efficient cutting and chip movement during mortise routing.

The black PTFE coating is not just there for looks. It is intended to protect the bit, reduce residue buildup, and help limit overheating. In real shop use, that means less drag when you are cutting in resinous stock or composite material and better consistency over repeated cuts. A coated cutter is especially useful when you are running production joinery and do not want pitch and dust packing up as quickly.

This cutter is made specifically for use on Domino machines for routing slots in solid wood and wood composites, with stated compatibility for the Festool DF700. The M8x1 shank specification is an important buying detail because it tells you the interface this bit uses. If you are replacing a worn cutter or setting up for a different Domino XL mortise size, that thread and machine match are what you need to confirm before ordering.

Who should buy it? Woodworkers, cabinet installers, furniture builders, and trim pros using a Festool Domino XL system. If your work involves larger loose tenon joinery and you need a dedicated 14 mm cutter that is built for repeated use, this CMT bit makes sense. If you do not own a Festool DF700, this is not a general-purpose straight router bit for handheld router work. It is a task-specific joinery cutter, and that is exactly why it matters.

A Purpose-Built Domino XL Cutter, Not a Generalist

The CMT 380.141.11 Bit for Domino Jointing Machines by Festool DF700 is the kind of accessory that only matters if you own the right machine, but if you do, it matters a lot.

• Who it's for: Woodworkers and installers running a Festool DF700 who need 14 mm loose tenon mortises for larger joints.
• Why it stands out: Solid carbide construction, PTFE coating, and a spec set clearly aimed at repeated production joinery instead of light occasional use.
• Worth knowing: This is a machine-specific joinery bit with an M8 x 1 interface, so check your DF700 setup before you hit buy.

• What machine is this bit designed for? Source data states it is for Festool DF700 Domino jointing machines.
• What size mortise does this cutter make? It has a 14 mm cutting diameter, intended for 14 mm Domino-style loose tenon joinery.
• What materials is it meant to cut? It is specified for routing slots in solid wood and wood composites.
• Is this a general-purpose straight router bit? No. Based on the source data, this is a dedicated bit for Domino jointing machine use, not a standard handheld router accessory.
