Product Description
CMT Slot Cutter 1-7/8" x 3/32" with 8mm Bore - 3 Tooth (822.324.11) is a precision-engineered carbide-tipped slot cutter designed for routing clean, accurate grooves in wood, panel materials, and plastics. Built for use with a compatible slot cutter arbor, this cutter excels at cutting biscuit slots, spline grooves, T-molding channels, and H-slot joinery applications. Its compact 1 7/8" cutting diameter and 3/32" kerf width make it a go-to choice for woodworkers, cabinet makers, and shop professionals seeking repeatable, splinter-free results across a wide range of materials.
Key Features
- 1 7/8" Cutting Diameter - sized for standard slot cutter arbor setups, delivering consistent groove depth and clean entry into solid wood, plywood, MDF, and composite panels.
- 3/32" Kerf Width (Teeth Thickness) - produces a precise, narrow slot ideal for splines, biscuits, T-molding, and panel joinery without excessive material removal.
- 12.7mm Cutting Depth - provides adequate slot depth for secure biscuit, spline, and T-slot connections in both face and edge applications.
- 8mm Bore Diameter - compatible with 8mm slot cutter arbors, ensuring a secure, centered fit and accurate rotation during cutting.
- 3-Tooth Configuration - three carbide-tipped teeth balance smooth chip evacuation with cutting efficiency, reducing vibration and heat buildup during routing passes.
- Hardmetal (HW) Carbide Construction - industrial-grade carbide tips deliver extended cutting life across hardwoods, softwoods, laminates, melamine, and plastic without frequent resharpening.
- Right-Hand Rotation - designed for standard router and CNC spindle rotation, ensuring correct cutting geometry and safe, predictable performance.
- 0.051" Plate Thickness - thin, rigid plate body minimizes deflection during cuts, contributing to slot accuracy and dimensional consistency.
Why This Product
- The 3/32" slot width is specifically suited for biscuit joinery, spline grooving, and T-molding installation - eliminating the guesswork of matching kerf width to common joinery standards.
- The 8mm bore and right-hand rotation make this cutter directly compatible with 8mm slot cutter arbors used on handheld routers, router tables, and CNC routing machines, giving you flexibility across machine setups.
- Hardmetal carbide construction means this cutter maintains its edge longer through demanding materials like melamine, chipboard, and laminates - reducing downtime for tool changes in production environments.
- With a 12.7mm cutting depth and a compact 1 7/8" diameter, this slot cutter is well suited for edge-joinery work on cabinet panels, door frames, and furniture components where controlled, repeatable grooves are essential.

Frequently Asked Questions
What arbor does the CMT 822.324.11 slot cutter require?
This slot cutter has an 8mm bore diameter and is designed for use with an 8mm slot cutter arbor. CMT offers compatible arbors in their 824 series for pairing with this cutter on handheld routers, router tables, and CNC machines.
What materials can this slot cutter cut?
The hardmetal carbide (HW) construction allows this cutter to work effectively in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic materials, making it versatile for both woodworking and panel fabrication tasks.
What is the slot width this cutter produces?
The teeth thickness is 3/32", which is the kerf width of the slot produced. This is the dimension to reference when matching the cutter to biscuit sizes, spline dimensions, or T-molding channel requirements.
Can this cutter be used on a CNC routing machine as well as a handheld router?
Yes. The right-hand rotation and 8mm bore make this slot cutter compatible with handheld routers, router tables, and CNC routing machines that accept 8mm arbor-mounted slot cutters. Always confirm your machine's arbor compatibility before use.
