CMT Two-Flute Slot Cutter with 1 1/8" Cutting Diameter and 5/16" Slot Width is a precision carbide-tipped routing tool engineered for clean, accurate horizontal groove cutting in solid hardwood, softwood, plywood, MDF, and composite panels. With a right-hand rotation, 8mm bore, and two industrial-grade carbide cutting edges, this slot cutter is purpose-built for biscuit joinery, spline routing, T-slot and H-slot fabrication, and panel assembly work. Designed for use with a compatible CMT 891.512M slot cutter arbor, it delivers smooth, consistent results whether mounted in a handheld router, router table, or CNC routing machine.

Key Features

• Carbide-Tipped Cutting Edges (HW Material Grade) - industrial-quality tungsten carbide tips stay sharp through repeated passes in solid timber, engineered wood, and panel materials, reducing the need for frequent replacement.
• Two-Flute (Z2) Configuration - dual cutting flutes produce a balanced, vibration-reduced cut, resulting in cleaner slot walls and a smoother finish on both face and edge grain.
• 1 9/64" Cutting Diameter - precisely sized cutting circle ensures consistent slot depth and width repeatability from pass to pass, which is critical in biscuit and spline joinery applications.
• 10.8mm Cutting Height - provides sufficient depth capacity for standard biscuit slots, spline grooves, and T-slot profiles in typical panel and solid wood thicknesses.
• 8mm Bore Diameter - compatible with the CMT 891.512M arbor system, enabling secure, centered tool mounting and reliable runout performance.
• Right-Hand Rotation - matches the standard spindle direction of handheld routers, router tables, and CNC machines, making setup straightforward and safe.
• Industrial Quality Construction - built to perform in flooring and inlay applications where edge sharpness and dimensional accuracy are held to tight tolerances.

Why This Product

• The two-flute carbide design runs smoothly through solid timber and engineered wood panels while remaining sharp after multiple passes - reducing downtime and tooling costs in production joinery environments.
• With a 10.8mm cutting height and a 1 9/64" diameter, this cutter is sized for precision slot work including biscuit joinery, spline grooves, and T-slot connectors used in panel assembly and furniture construction.
• Compatibility with the CMT 891.512M arbor system means this cutter integrates directly into an existing CMT arbor setup - no adapters or workarounds required for a secure, centered fit.
• The 8mm bore and right-hand rotation make this cutter suitable for handheld routers, router tables, and CNC routing machines, giving woodworkers and production shops flexibility across different workflows.
