Product Description
The CMT 822.003.11 Two-Flute Slot Cutter is a carbide-tipped slot cutting blade engineered for precise horizontal grooving in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. Designed to mount on a CMT 890.501, 890.502, or 890.503 arbor, this 1 3/4 in. diameter cutter delivers clean, consistent slots for biscuit joinery, spline grooves, panel connections, T-slot routing, and H-slot applications. With industrial-grade carbide tips and a right-hand rotation design, it runs smoothly through solid timber and engineered wood while maintaining sharp cutting edges pass after pass - making it a dependable choice for flooring, inlay work, and cabinet panel joinery.
Key Features
- Two-Flute Carbide-Tipped Design (Z=2, HW Material) - dual cutting edges in industrial-quality carbide allow the cutter to slice through solid and engineered wood smoothly, staying sharp through repeated passes without frequent resharpening.
- 1 3/4 in. Cutting Diameter - sized specifically for standard slot-cutting applications in flooring, panel joinery, and inlay work, giving you reliable reach and consistent groove geometry.
- 15/64 in. Cutting Height - produces a narrow, precise slot depth suited for biscuit slots, spline grooves, and T-slot or H-slot profiles in a single pass.
- 8mm Bore Diameter - fits directly onto compatible CMT 890.501, 890.502, and 890.503 arbors, ensuring secure mounting and minimal runout for accurate, repeatable cuts.
- Right-Hand Rotation (RH) - matches the standard rotation direction of handheld routers, router tables, and CNC routing machines, making this cutter broadly compatible with common workshop setups.
- Industrial Quality Construction - built to professional standards so it performs consistently in high-volume production environments as well as demanding shop applications.
Why This Product
- If you need clean, repeatable horizontal slots for biscuits, splines, or panel connectors, the two-flute carbide geometry cuts through both solid timber and engineered boards without tearing or burning the material.
- The 8mm bore and direct compatibility with CMT 890.501, 890.502, and 890.503 arbors means no adapter guesswork - just mount the cutter on the correct arbor and it is ready to run.
- At 1 3/4 in. diameter with a 15/64 in. cutting height, this cutter is purpose-sized for biscuit slot cutting and spline groove routing, giving you the precise slot profile those joinery methods require.
- Industrial-grade carbide tips hold their edge through flooring runs and inlay production, reducing downtime for bit changes and keeping your workflow moving on larger projects.
