CMT Reversible Throwaway Knives in Carbide - 10-Pack (23/32" x 23/32" x 3/32") are precision-ground, indexable carbide insert knives engineered for use in cutter heads and insert shaper systems on spindle moulders and profile machines. Each knife features four cutting edges ground at 35 deg., so when one edge dulls, you simply rotate to a fresh edge - extending usable life and reducing downtime. Manufactured from K1920 grade carbide, these reversible knives deliver consistent cutting performance on hardwood, softwood, MDF, chipboard, and plywood. This pack includes 10 knives, keeping your operation running without constant restocking.

Key Features

• K1920 Grade Carbide Material - a high-grade tungsten carbide compound that maintains edge sharpness longer than standard steel alternatives, making it well suited for abrasive engineered wood products like MDF and chipboard as well as solid hardwoods and softwoods.
• Four Cutting Edges at 35 deg. - each knife provides four usable cutting edges, so you get up to four times the service life from a single insert before disposal, lowering per-edge cost and reducing tool change frequency.
• Reversible Indexable Design - rotating to a fresh edge takes seconds, minimizing machine downtime and keeping production moving without the need to remove and resharpen conventional knives.
• Precision Ground Tolerances - each knife is ground to exact dimensional tolerances (18mm length x 18mm height x 2.45mm thickness), ensuring consistent profile quality and reliable seating in compatible cutter head bodies.
• 10-Piece Pack - having a ready supply of spare inserts on hand eliminates production stoppages, giving shops and job sites a practical working quantity without over-ordering.
• Throwaway Knife Format - when all four edges are spent, the insert is simply replaced rather than sent for resharpening, eliminating resharpening costs and scheduling delays.

Why This Product

• Four cutting edges per insert mean you are effectively getting four knives in one - ideal for high-volume shops that run spindle moulders or profile machines continuously and need to control tooling costs.
• K1920 carbide grade holds up against the abrasive resins and glues found in MDF, chipboard, and plywood, making these inserts a practical choice for operations that process engineered wood alongside solid lumber.
• The reversible indexable format allows edge changes directly at the machine without disassembly or resharpening, which translates to faster turnaround between production runs and less skilled labor required for tool maintenance.
• Stocking 10 knives at a time ensures continuous availability of fresh cutting edges, reducing the risk of production halts caused by waiting for replacement tooling to arrive.
