CMT Reversible Throwaway Knives - Carbide 1-31/32 in. x 31/64 in. x 1/16 in., 10-Pack are precision-ground indexable carbide insert knives engineered for use with cutter heads on spindle moulders, profile machines, and compatible insert shaper systems. Each knife features two cutting edges ground at 35 deg., so when the first edge dulls, you simply rotate the knife to expose a fresh cutting surface - extending the effective life of every insert and reducing downtime between blade changes. The K1920 carbide grade delivers the hardness and wear resistance needed to handle hardwood, softwood, MDF, chipboard, and plywood with consistent results.

Key Features

• Two cutting edges per knife at 35 deg. - rotating to a fresh edge when the first dulls means each insert delivers twice the cutting life before replacement, lowering the cost per linear foot of material processed.
• K1920 carbide material - a professional-grade tungsten carbide formulation that maintains a sharp cutting edge through extended runs on hardwood, softwood, MDF, and chipboard, reducing resharpening frequency.
• Reversible throwaway design - no resharpening equipment required; when both edges are spent, the knife is simply replaced, keeping setup time minimal and consistent profile quality repeatable.
• Precision dimensions: 50mm length x 12mm cutting height x 1.5mm thickness - ground to exact tolerances so each knife seats squarely and repeatably in the cutter head, eliminating profile variation between knife changes.
• Standard indexable knife format - compatible with cutter heads designed for this insert style, offering straightforward interchangeability across compatible shaper and profile machine tooling systems.
• 10 knives per pack - provides enough inserts for multiple setups and edge rotations, supporting uninterrupted production without frequent reordering.

Why This Product

• The dual-edge reversible design means you get two usable cutting edges from a single insert - straightforward value for woodworking shops processing high volumes of hardwood, softwood, MDF, or chipboard profiles.
• The throwaway format eliminates the need for a carbide grinder or resharpening service - swap edges or replace the insert on the machine without sending tooling out for service, keeping production moving.
• K1920 carbide grade is specifically suited to the demands of profile and moulding work, holding an edge through abrasive materials like MDF and chipboard where high-speed steel inserts wear prematurely.
• Buying in a 10-pack means you have a ready supply of matched inserts on hand - consistent knife dimensions across the pack ensure uniform profile output every time a knife is indexed or replaced.
