The CMT 822.007.11 Two-Flute Slot Cutter is an industrial-quality, carbide-tipped routing bit engineered for precise horizontal slot cutting in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. With a 2 1/8 in. cutting diameter, a 5/16 in. radius, and a 23/64 in. cutting height, this right-hand rotation cutter is purpose-built for flooring and inlay applications where clean, consistent groove profiles are critical. Designed to be used with a slot cutter arbor from the CMT 890.527 series, it runs smoothly through dense timber and engineered wood while maintaining a razor-sharp edge across multiple passes - making it a reliable choice for biscuit slot cutting, spline groove routing, T-slot joinery, and panel assembly work.

Key Features

• Two-Flute Carbide-Tipped (HW) Design - dual cutting edges deliver smooth, efficient material removal and reduce load on the router motor, extending both tool and machine life in demanding production environments.
• 5/16 in. Radius Profile - produces a precise, consistent groove geometry ideal for flooring tongue-and-groove joints, inlay work, and spline channels without secondary passes or hand fitting.
• 23/64 in. Cutting Height - a well-proportioned cutting height that balances material engagement with chip clearance, reducing burning and tear-out in solid wood and engineered panels.
• 2 1/8 in. Cutting Diameter - a large working diameter allows the cutter to reach deep into workpieces and maintain consistent slot depth across the full width of the cut.
• 8 mm Bore (F Diameter) - precision-bored arbor hole ensures secure, centered mounting on compatible slot cutter arbors, minimizing vibration and improving cut accuracy.
• Right-Hand Rotation (RH) - matches standard router and CNC spindle direction, making this cutter compatible with handheld routers, router tables, and CNC routing machines without modification.
• HW (Hard Metal / Carbide) Material - industrial-grade carbide maintains cutting sharpness even after repeated passes through hardwoods and composite materials, reducing resharpening frequency and downtime.
• Compatible with CMT 890.527 Arbor Series - designed for use with the matching CMT slot cutter arbor system, providing a stable, vibration-dampened platform for accurate, repeatable grooves.

Why This Product

• Flooring and inlay professionals who need a slot cutter that stays sharp across multiple production runs will benefit from the HW carbide construction, which resists edge wear even in solid hardwood and dense engineered materials.
• The 5/16 in. radius and 23/64 in. cutting height work together to produce a groove profile that fits standard splines and biscuits accurately, eliminating the need for trial-and-error test cuts and saving setup time.
• With a 2 1/8 in. working diameter and two cutting flutes, this cutter achieves smooth, clean slot walls in a single pass through most woodworking materials - reducing finishing steps and improving joint quality.
• The 8 mm precision bore and right-hand rotation make this cutter a direct fit for handheld routers, router tables, and CNC routing machines when paired with the CMT 890.527 arbor, offering flexibility across different shop setups without additional adapters.
