CMT 822.364.11B Slot Cutter by CMT is a precision-engineered carbide-tipped cutting blade designed for routing horizontal slots and grooves in wood, composite panels, and more. With a 1 7/8" cutting diameter, 1/4" teeth thickness, and a 1/2" shank, this three-wing cutter handles a wide range of joinery tasks - from spline grooves and biscuit slots to T-molding channels and tongue-and-groove joints. The anti-kickback body design, micrograin carbide tips, and CMT orange PTFE non-stick coating combine to deliver cleaner cuts, reduced heat buildup, and extended tool life across demanding routing applications.

Key Features

• Anti-Kickback Design - limits the amount of material each tooth can engage per pass, reducing the risk of sudden tool grab and improving operator safety during slotting operations.
• Micrograin Carbide Tips (HW Material) - the dense, fine-grain carbide construction resists chipping and dulling, maintaining a sharp cutting edge through extended use in hardwood, softwood, plywood, and panel materials.
• CMT Orange PTFE Non-Stick Coating - prevents pitch, resin, and adhesive buildup on the blade surface, reduces friction-generated heat, protects against corrosion, and extends the service life of the cutter.
• Three-Wing (3-Tooth) Configuration - three evenly spaced cutting edges produce smooth, consistent slot walls and allow efficient chip clearance, reducing tearout in finished panels and joinery work.
• 1/4" Teeth Thickness - cuts standard 1/4" slots in a single pass, making it directly compatible with common spline stock, T-molding, and biscuit joint workflows.
• 0.177" Plate Thickness - the precision-ground blade body fits arbors designed for this plate dimension, ensuring accurate alignment and a stable cutting path.
• 12.7mm Cutting Depth - the 22mm (7/8") diameter bearing on compatible arbors provides up to 12.7mm (1/2") of cutting depth, giving ample groove depth for strong spline and panel joints.
• 1/2" Shank - the heavy-duty 1/2" shank offers greater rigidity and reduced vibration compared to smaller shank options, contributing to cleaner slot edges and better router control.
• Right-Hand Rotation - standard RH rotation is compatible with the vast majority of routers, router tables, and CNC routing machines used in woodworking shops.

Why This Product

• Handles nearly unlimited slotting applications - biscuit joints, spline grooves, T-molding channels, and tongue-and-groove joinery can all be accomplished with this one cutter blade by pairing it with the appropriate CMT 824 series arbor.
• The anti-kickback body combined with micrograin carbide tips means the cutter stays sharper longer and behaves more predictably at the router table, reducing both downtime for resharpening and the risk of workpiece damage.
• The orange PTFE non-stick coating is especially valuable when routing resinous softwoods, MDF, melamine, or laminated panels where pitch and adhesive buildup typically slow productivity and degrade cut quality.
• At 1/4" cutting width and 12.7mm depth capacity, this cutter is sized for the most common slot joinery tasks in cabinet making and millwork, making it a practical everyday choice rather than a specialty-only tool.
