Product Description
CMT 822.332.11 Slot Cutter - 1 7/8" Diameter x 1/8" Teeth Thickness, 8mm Bore, 3-Tooth is a precision carbide-tipped slot cutting blade engineered for routers and router tables. Designed for cutting clean, accurate grooves in wood, panel products, and plastic, this slot cutter handles a wide range of joinery tasks including biscuit slot cutting, spline groove routing, T-molding installation, and panel joinery. With a right-hand rotation, a 12.7mm cutting depth, and a compact 3-tooth configuration, it delivers controlled, consistent results in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic materials.
Key Features
- 1 7/8" Cutting Diameter - provides a well-proportioned cutting radius suited to standard slot and groove work, giving you consistent groove geometry across a variety of joinery applications.
- 1/8" Teeth Thickness - cuts a precise 1/8" wide slot in a single pass, eliminating the need for multiple passes when sizing grooves for splines, biscuits, or T-molding.
- 8mm Bore Diameter - sized to fit 8mm slot cutter arbors in the CMT 824 series, ensuring a secure, centered fit that reduces vibration and improves cut accuracy.
- 12.7mm Cutting Depth - delivers ample groove depth for most joinery applications, supporting solid panel connections and reliable T-slot and H-slot profiles.
- 3-Tooth Carbide Configuration (HW Material) - three tungsten carbide cutting teeth provide a smooth, efficient cutting action while maintaining sharp edges longer than standard steel, reducing the frequency of blade changes.
- Right-Hand (RH) Rotation - matches the standard rotation of handheld routers, router tables, and CNC routing machines, making installation and setup straightforward.
- 0.051" Plate Thickness - a thin, precise plate minimizes material waste and allows the cutter to seat accurately on the arbor for repeatable, consistent slot depths.
Why This Product
- The 1/8" slot width cuts spline grooves, biscuit slots, and T-molding channels in a single controlled pass - saving setup time and reducing the risk of oversized or misaligned grooves.
- The 3-tooth tungsten carbide design handles a broad range of materials from solid hardwood to melamine and plastic, making this one blade practical across multiple project types and material categories.
- The 8mm bore and shank specification matches the CMT 824 series arbor system, providing a dedicated, manufacturer-matched fit that supports accurate, repeatable groove cutting on router tables and handheld routers alike.
- With a 12.7mm cutting depth and right-hand rotation, this slot cutter integrates cleanly into standard router setups - including CNC routing machines - without special tooling or adapters.

Frequently Asked Questions
What arbor is required to use the CMT 822.332.11 slot cutter?
This slot cutter has an 8mm bore and is designed to be used with an 8mm slot cutter arbor. CMT's 824 series arbors are the manufacturer-matched option for this blade. Always confirm the bore diameter of the arbor matches the 8mm specification before mounting.
What width of slot does this cutter produce?
The CMT 822.332.11 has a teeth thickness of 1/8", so it cuts a 1/8" wide slot in a single pass. This makes it well-suited for standard spline grooves, biscuit slots, and T-molding channels that require a 1/8" kerf.
What materials can this slot cutter handle?
The 3-tooth tungsten carbide (HW) construction allows this slot cutter to work effectively in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. The carbide tips maintain cutting sharpness longer than standard steel across these varied materials.
What machines are compatible with this slot cutter?
This slot cutter is compatible with handheld routers, router tables, and CNC routing machines. It is built for right-hand (RH) rotation, which is the standard direction of travel on these machine types. Always verify that your arbor and machine spindle match the 8mm shank specification before use.
