CMT Solid Carbide Reversible Knives - R3 Profile, 19.5x9x1.5mm, 10-Piece Pack are precision-ground throwaway insert knives engineered for profiled rounding cuts on spindle moulders, profile machines, and router tables equipped with compatible cutter heads. Made from K1920 grade solid carbide, these reversible insert knives deliver extended cutting life on hardwood, softwood, MDF, chipboard, and plywood - giving woodworking professionals a reliable, consistent edge for demanding production and finish work.

Key Features

• K1920 Solid Carbide Material - tungsten carbide construction outlasts standard high-speed steel knives and maintains a sharp edge through prolonged cuts in hardwood, MDF, chipboard, and plywood, reducing downtime for blade changes.
• 4 Cutting Edges Per Knife - each reversible throwaway knife provides four usable cutting edges, meaning you rotate or flip to a fresh edge when one dulls instead of regrinding, dramatically extending the usable life of every piece in the pack.
• R3 Profiled Rounding Geometry - the 3mm radius profile delivers smooth, repeatable rounding and edge profiling results, producing consistent finished profiles across large production runs without setup variation.
• 35 deg. Knife Angle - the precisely ground 35 deg. cutting angle optimizes chip clearance and surface finish quality, reducing tearout on both soft and hard materials for cleaner results with less post-processing.
• 19.5x9x1.5mm Dimensions - exact tolerances on length, cutting height, and thickness ensure a secure, precise seat in compatible cutter head bodies, eliminating chatter and maintaining dimensional accuracy across the profile.
• 10-Piece Pack - the multi-piece quantity provides an ample supply for production shops, allowing rapid knife replacement and keeping machines running with minimal interruption.

Why This Product

• For shops running high-volume rounding and edge profiling operations, the 4-cutting-edge reversible design means each knife delivers up to four times the service life of a single-edge insert - lowering cost per linear foot of material processed.
• The K1920 solid carbide grade is formulated for demanding cutting applications, making these knives a practical choice for operations that regularly process abrasive materials like MDF, chipboard, and hardwood where softer tooling materials wear quickly.
• At 19.5x9x1.5mm with a 1.5mm thickness and 9mm cutting height, this knife profile is a direct-fit throwaway replacement solution designed to drop into compatible cutter head systems without regrinding or custom fitting.
• The 10-piece pack quantity keeps a ready stock of sharp cutting edges on hand, supporting continuous production runs and reducing the risk of machine downtime caused by worn tooling.
