CMT Solid Carbide Reversible Insert Knives - 20x12x1.5mm, 35 deg. Bevel, 2 Cutting Edges, 10-Pack by CMT are precision-ground throwaway insert knives engineered for demanding profiling and molding applications on spindle moulders, profile machines, and router tables equipped with compatible cutter heads. Each knife is manufactured from K2250 solid carbide - a tungsten carbide grade selected for its hardness and wear resistance - delivering extended cutting life across hardwood, softwood, MDF, chipboard, and plywood. The reversible design means two sharp 35 deg. cutting edges per knife, so when one edge dulls, the insert simply flips to expose a fresh edge, reducing downtime and maximizing the value of every pack.

Key Features

• K2250 Solid Carbide Material - tungsten carbide construction withstands the abrasion of dense hardwoods, MDF, and chipboard far longer than high-speed steel alternatives, reducing how often you stop to change inserts.
• Reversible 2-Edge Design - two 35 deg. cutting edges per knife mean you effectively double usable life per insert by indexing to the second edge when the first dulls, lowering cost per edge significantly.
• 35 deg. Bevel Angle - the standard 35 deg. geometry is matched to common insert cutter head systems, ensuring correct seating, proper cutting action, and clean profile results on profiling and grooving operations.
• Precision-Ground Dimensions (20x12x1.5mm) - tight dimensional tolerances across length, height, and thickness ensure consistent knife-to-knife fit within the cutter head, delivering repeatable profile quality cut after cut.
• 10-Knife Pack - multiple inserts per pack means you have backup edges on hand when switching between materials or replacing worn knives mid-run, keeping production moving without waiting for restocking.
• Throwaway/Indexable Format - no resharpening required; when both edges are spent, the knife is replaced rather than reground, eliminating the time and cost of a dedicated sharpening service for these inserts.

Why This Product

• For woodworking shops that run spindle moulders or profile machines through long production cycles, the K2250 solid carbide construction and reversible format mean fewer insert changes and more consistent edge geometry from the first cut to the last.
• The standard 35 deg. bevel and precise 20x12x1.5mm dimensions are designed to fit compatible insert shaper cutter head systems, making these a reliable replacement choice when original inserts wear out during edge profiling, rabbeting, or grooving operations.
• Because each knife carries two indexed cutting edges and the pack contains 10 knives, you receive a total of 20 cutting edges per pack - practical coverage for extended runs on hardwood, softwood, MDF, chipboard, and plywood without interrupting workflow.
• The throwaway indexable design removes the variable of resharpening quality from the equation - every fresh edge is ground to the same factory tolerance, so profile consistency does not degrade over successive edge changes the way it can with reground knives.
