CMT Reversible Throwaway Knives in Carbide - 41/64" x 7/8" x 13/64" - 10-Pack are precision-ground, solid carbide insert knives engineered for edge rounding and chamfering operations on spindle moulders, profile machines, and compatible insert shaper systems. Manufactured from K1920 carbide grade material, these reversible throwaway knives deliver consistent, repeatable cutting performance across a wide range of wood-based materials - from dense hardwood to MDF and chipboard. Each knife features a 1.5mm corner radius designed specifically for edge rounding profiles, and the reversible design means a fresh cutting edge is always within reach, extending the useful life of every knife in the pack.

Key Features

• K1920 carbide grade material - a professional-grade tungsten carbide formulation that maintains cutting edge sharpness longer on hardwood, softwood, MDF, and chipboard compared to high-speed steel alternatives.
• Reversible (throwaway) knife design - rotate to the opposite edge when one side dulls, effectively doubling the cutting life per knife and reducing downtime for changeovers.
• R = 1.5mm corner radius - purpose-built for consistent edge rounding profiles, delivering smooth, uniform chamfers without requiring custom grinding.
• Precision ground to exact tolerances - each knife conforms to published dimensional specs (L x H x K), ensuring a secure, repeatable fit in compatible cutter head systems and minimizing vibration during operation.
• 10-piece pack - provides a ready supply of replacement knives so production can continue uninterrupted when edges are rotated or knives are replaced.

Why This Product

• The 1.5mm radius geometry is purpose-matched to edge rounding and chamfering work - if your application requires a specific, consistent profile on workpiece edges, this knife eliminates the guesswork associated with freehand grinding or improvised setups.
• K1920 carbide holds its edge through demanding production runs on abrasive materials like MDF and chipboard - reducing the frequency of knife changes and keeping spindle moulders and profile machines running productively.
• The reversible, throwaway format means no resharpening is required - simply rotate to a fresh edge or swap the knife, making these inserts well-suited for shops that prioritize fast turnaround over in-house sharpening services.
• Buying in a 10-piece pack keeps a meaningful stock of matched knives on hand, so cutter heads can be fully loaded with knives of the same specification and wear characteristics at every change.
