CMT 822.360.11 Slot Cutter by CMT is a 3-flute carbide-tipped routing cutter designed for precise slot cutting in wood, panel products, and plastic materials. With a 1 7/8 in. cutting diameter and a 15/64 in. kerf width, this slot cutter excels at producing clean, consistent grooves for splines, biscuits, T-molding installation, and panel joinery. Engineered for use without an arbor included, it mounts directly onto a compatible CMT 824 series arbor and works with handheld routers, router tables, and CNC routing machines for both professional and production-level applications.

Key Features

• 3-Flute Carbide-Tipped Design (HW material): three cutting edges distribute load evenly across the cut, resulting in a smoother slot finish and longer service life compared to single- or double-flute alternatives.
• 1 7/8 in. Cutting Diameter: a mid-range diameter that provides reliable reach into workpiece edges without excessive material removal, making it well-suited for spline grooves and biscuit slots in standard panel thicknesses.
• 15/64 in. Teeth Thickness: precisely matched kerf width produces slots that accept standard T-molding and spline connectors with minimal gap or slop, reducing the need for post-routing adjustments.
• 12.7mm Cutting Depth: sufficient depth for biscuit joinery, spline routing, and T-slot profiles in solid hardwood, softwood, plywood, MDF, chipboard, laminates, and melamine panels.
• 8mm Bore and 8mm Shank Compatibility: the 8mm bore pairs directly with CMT 824 series arbors, keeping setup straightforward and tool changes quick on the router table or handheld router.
• Right-Hand (RH) Rotation: matches the standard rotation direction of virtually all handheld routers and router table setups, so the cutter runs safely and feeds correctly without special configuration.
• 0.177 in. Plate Thickness: a relatively thin plate body reduces drag through the cut, which helps keep heat buildup low and extends the usable life of the carbide edges.

Why This Product

• When a woodworker or cabinetmaker needs repeatable, accurately sized slots for biscuit joinery or spline grooves, the 3-flute configuration and precise 15/64 in. kerf deliver consistent results pass after pass without requiring multiple test cuts.
• The 8mm bore and 8mm shank sizing make this cutter a direct fit for CMT 824 series arbors, eliminating the guesswork of mixed-standard tooling setups and keeping the tool change process efficient on a busy bench or production table.
• Compatibility with solid hardwood, softwood, MDF, plywood, chipboard, laminates, melamine, and plastic means this single cutter covers the broad range of materials found in furniture, cabinet, and millwork shops - reducing the need for multiple specialty bits.
• The 12.7mm cutting depth paired with the 1 7/8 in. diameter provides the geometry needed for T-molding slots and H-slot profiles used in display cases, store fixtures, and frameless cabinetry, making this a versatile addition to any router bit collection.
