CMT Reversible Throwaway Carbide Knives - 41/64" x 7/8" x 13/64" - 10-Pack are precision-ground, K1920 carbide insert knives engineered for edge rounding and chamfering operations at a 45 deg. angle. These reversible throwaway inserts are sized at 16mm length x 22mm cutting height x 5mm thickness and deliver consistent, repeatable profile quality on a wide range of wood-based materials. Sold in a 10-piece pack, they are a practical solution for shops that demand reliable edge finishing performance from their spindle moulders, profile machines, and cutter head systems.

Key Features

• K1920 Carbide Material - a high-grade tungsten carbide grade that holds a sharp cutting edge longer than standard tooling steel, reducing the frequency of knife changes during production runs on hardwood, softwood, MDF, and chipboard.
• Reversible Design at 45 deg. - each knife has multiple usable cutting edges specifically configured for 45 deg. edge rounding and chamfering, so rotating to a fresh edge extends the usable life of every insert and lowers per-edge cost.
• Throwaway Insert Format - no resharpening required; when all edges are spent, the insert is replaced rather than sent out for grinding, keeping machine downtime to a minimum and eliminating resharpening costs.
• Precision Dimensions: 16mm x 22mm x 5mm - ground to exact tolerances so each insert seats consistently in compatible cutter heads, ensuring uniform chamfer depth and profile quality across every piece.
• 10-Piece Pack - stocking a full pack of 10 knives means a ready supply of fresh edges on hand, supporting uninterrupted production without rush ordering individual inserts.

Why This Product

• For shops running continuous edge rounding or chamfering passes, the reversible insert design means less machine downtime - simply rotate or replace the knife rather than stopping to resharpen, keeping production moving.
• The K1920 carbide grade is matched to the demands of composite and solid wood materials, making these inserts a dependable choice for operations that work across a variety of panel and lumber products in a single shift.
• The 45 deg. geometry is purpose-built for edge rounding and chamfering work, giving operators a dedicated insert rather than a general-purpose blade - the result is a cleaner, more consistent chamfer profile on every workpiece.
• Buying in a 10-piece pack provides a practical on-hand inventory of inserts, reducing the risk of production delays caused by running out of usable cutting edges mid-job.
