CMT 823.364.11B Slot Cutter by CMT is a precision-engineered groove-cutting router bit designed for woodworkers who need clean, repeatable slots for splines, biscuits, panel connectors, and joinery work. With a 1 7/8" cutting diameter, a 1/4" blade thickness, and a 1/2" cutting depth, this three-tooth carbide-tipped cutter handles solid hardwood, softwood, plywood, MDF, and sheet goods with consistent results. The included 22mm (7/8") bearing guides the cut for accurate, fence-free routing on router tables and handheld routers alike, making it a practical choice for cabinet panels, furniture assembly, and decorative groove work.

Key Features

• 1 7/8" Cutting Diameter with 1/4" Blade Thickness - produces precisely dimensioned grooves sized for standard splines, biscuits, and panel connectors in a single pass, eliminating the need for multiple setups.
• 3-Tooth Carbide-Tipped (HW) Cutters - three cutting edges distribute load evenly across the blade, extending cutter life and delivering smoother groove walls compared to single- or two-tooth designs.
• Included 22mm (7/8") Bearing - provides a fixed reference surface for guided freehand routing, delivering a consistent 1/2" (12.7mm) cutting depth without a fence or jig.
• Orange PTFE Non-Stick Coating - resists pitch, resin, and adhesive buildup on the bit body, reducing friction-related heat and protecting the cutter between uses and during storage.
• Anti-Kickback Design - limits the maximum depth of engagement per pass, reducing the risk of sudden, dangerous grab events that can occur with thinner or softer stock.
• Right-Hand (RH) Rotation - compatible with all standard router collets and matches the feed direction of conventional handheld and table-mounted routers.
• 1/2" Shank - the larger shank diameter transfers torque more efficiently than 1/4" shanks, reducing vibration and chatter for cleaner slot walls.
• 0.175" Plate Thickness - a precisely dimensioned body keeps the blade aligned and stable in the collet, supporting accurate, repeatable slot positioning across production runs.

Why This Product

• Versatile joinery in one setup - the combination of a 1 7/8" diameter, 1/4" kerf, and guided bearing means this cutter handles T-slots, spline grooves, rabbet joints, and panel connector channels without changing bits or reconfiguring the router table.
• Three carbide teeth for longer service life - HW-grade carbide tipping with three cutting edges means the bit stays sharp longer under repeated passes through hardwood and engineered panels, reducing downtime for tool changes.
• Anti-kickback geometry for safer operation - the built-in anti-kickback design limits bite depth per revolution, making this cutter safer to use in handheld applications where workpiece control is more demanding.
• Bearing included for immediate use - the 7/8" bearing ships with the cutter, so there is no need to source a separate guide bearing before starting a project - the bit is ready for guided slot cutting straight out of the package.
