CMT 822.010.11 Two-Flute Slot Cutter by CMT is an industrial-quality, carbide-tipped routing tool engineered for precision slot cutting in solid hardwood, softwood, and composite sheet materials. Designed for use with a slot cutter arbor from the CMT 890.537M series, this 1 3/4 in. diameter cutter produces clean, consistent grooves for biscuit joinery, spline fitting, T-slot and H-slot assembly, and panel joinery applications. Its two-flute configuration and right-hand rotation deliver smooth, controlled material removal - making it well suited for both handheld router and router table setups as well as CNC routing machines. Whether you are cutting inlay channels or joining panels with splines, this slot cutter is built to run easily and smoothly through solid and engineered wood while maintaining sharp cutting edges across repeated passes.

Key Features

• Carbide-Tipped (HW) Cutting Edges - industrial chrome carbide tips stay sharp through repeated passes in hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic, reducing downtime from frequent bit changes.
• Two-Flute Design (Z2) - dual cutting flutes balance the bit during rotation, promoting smoother cuts and reducing vibration for cleaner slot walls and more accurate groove dimensions.
• 1/4 in. Cutting Height - produces a precise 1/4 in. deep slot in a single pass, ideal for standard biscuit slots, spline grooves, and T-slot channels without multiple setup adjustments.
• 1 3/4 in. Diameter - the wider cutter diameter provides stability during routing and is compatible with the CMT 890.537M arbor system for secure, centered bit mounting.
• 8mm Bore Diameter - machined bore fits directly onto compatible CMT arbors, ensuring a tight, concentric mount that minimizes runout during operation.
• Right-Hand Rotation (RH) - standard right-hand rotation is compatible with the vast majority of handheld routers, router tables, and CNC spindles, requiring no special tooling or setup.
• Orange Shield Non-Stick Coating - prevents pitch and resin buildup on the bit body, reduces heat accumulation during cuts, protects against corrosion, and extends overall tool life between cleanings.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing (HIP) minimizes internal voids and material failure points, extending cutting life in demanding production environments.
• Tri-Metal Brazing (Silver-Copper-Silver) - a three-layer brazing bond secures each carbide tip more reliably than single-layer methods, reducing the risk of tip separation when routing harder wood species or composite materials.
• Anti-Kickback Design - controls depth of cut on each flute to limit the amount of material removed per bite, reducing the risk of sudden kickback for safer, more controlled routing.

Why This Product

• The combination of SinterHIP carbide and Tri-Metal Brazing means the cutting edges resist wear and tip loss even in demanding applications like flooring inlay and panel joinery - reducing the frequency of bit replacement in production settings.
• The Orange Shield non-stick coating actively prevents resin and pitch from bonding to the bit surface, which is especially valuable when routing resinous softwoods, laminates, or melamine where buildup would otherwise slow cuts and scorch edges.
• Compatibility with the CMT 890.537M arbor system allows this cutter to be swapped quickly onto an existing setup, making it easy to change groove depths or stack multiple cutters for wider slots without purchasing an entirely new assembly.
• With a 1/4 in. cutting height and 1 3/4 in. diameter optimized for horizontal slot work, this bit handles the full range of common joinery groove tasks - from biscuit slots in solid hardwood furniture to T-slot channels in sheet goods - in a single, consistent pass.
