CMT Reversible Throwaway Carbide Knives - 41/64 x 7/8 x 13/64 Inch - 10-Pack are precision-ground, reversible insert knives designed for edge rounding and chamfering applications on spindle moulders, profile machines, and compatible insert shaper systems. Manufactured from K1920 grade carbide, these throwaway-style inserts deliver consistent profile quality across hardwood, softwood, MDF, chipboard, and plywood - with the added economy of a reversible design that extends usable cutting life before replacement.

Key Features

• K1920 Carbide Material - a purpose-selected tungsten carbide grade that maintains a sharp, clean cutting edge through demanding production runs on both natural wood and engineered sheet goods.
• Reversible Knife Design - when one cutting edge dulls, simply rotate the insert to expose a fresh edge, effectively doubling the value of each individual knife before disposal.
• R = 2mm Radius Edge Rounding Profile - engineered to produce a precise, repeatable 2mm radius chamfer or edge rounding on workpiece corners, reducing sanding time and delivering a finished result directly off the cutter head.
• Precision-Ground Dimensions (16mm x 22mm x 5mm) - exact tolerances ensure consistent seating in the cutter head pocket, which translates directly to uniform profile quality across an entire production batch.
• Throwaway Insert Format - no resharpening required, eliminating the cost and downtime of sending knives out for regrinding while keeping replacement tooling costs predictable.
• 10-Piece Pack - a generous supply quantity means fewer purchasing interruptions during high-volume production work, keeping machines running with fresh tooling on hand.

Why This Product

• The reversible, throwaway format solves the productivity problem of stopping production to resharpen tooling - rotate to a fresh edge in seconds and keep cutting, with no specialized sharpening equipment needed.
• At a 2mm edge rounding radius, these inserts are sized for fine detail work where consistent, repeatable profiles matter - such as furniture components, cabinet doors, and architectural moulding produced in volume runs.
• K1920 carbide grade is matched to the demands of both hardwood and engineered board materials, making these knives a practical single-insert solution when a shop processes a mixed range of wood species and panel products.
• Buying in a 10-piece pack reduces per-unit cost and ensures a ready supply of matched inserts, so a full cutter head can be loaded with fresh tooling at one time rather than mixing worn and new edges.
