CMT Solid Carbide Reversible Insert Knives - R1 Radius, 12x12x1.5mm, 4 Cutting Edges, 10-Piece Pack are precision-ground tungsten carbide insert knives engineered for profile shaping, edge molding, and grooving operations on spindle moulders, profile machines, and router tables equipped with compatible cutter heads. Each square insert knife features a 1mm radius cutting profile and four usable cutting edges, so when one edge dulls, simply rotate to a fresh edge and continue working - maximizing the usable life of every knife in the pack. With an angle of 35 deg. and a uniform 12x12x1.5mm body, these inserts deliver consistent, repeatable profile results across hardwood, softwood, MDF, chipboard, and plywood.

Key Features

• Solid carbide (F1730 grade) construction - tungsten carbide material resists wear significantly longer than high-speed steel, reducing replacement frequency when cutting dense hardwoods, abrasive MDF, and engineered sheet goods.
• 4 cutting edges per insert - rotating to a new edge extends usable knife life up to four times compared to a single-edge insert, lowering cost-per-cut over the life of the pack.
• R1 (1mm radius) profile - produces a precise, consistent radius profile suitable for edge profiling, molding, rabbeting, and grooving applications where a controlled corner geometry is required.
• 35 deg. cutting angle - optimized rake geometry promotes clean chip ejection and smooth surface finish, reducing tearout on both long-grain and cross-grain cuts.
• 12x12x1.5mm precision-ground body - exact dimensional tolerances ensure the knife seats correctly in compatible insert cutter heads, maintaining profile accuracy cut after cut.
• 10 inserts per pack - having a full set of replacement knives on hand minimizes downtime during production runs and allows for immediate rotation without interrupting workflow.

Why This Product

• Four usable cutting edges on a single square insert mean you replace knives far less often - a practical advantage for production shops running high volumes of hardwood or abrasive sheet material.
• The 1mm radius profile paired with a 35 deg. cutting angle delivers clean, precise edges on hardwood, softwood, MDF, chipboard, and plywood without the need for secondary sanding or cleanup passes.
• The F1730-grade solid carbide material maintains its edge geometry under the heat and friction generated by demanding profile and molding operations, where softer tool materials would dull prematurely.
• With 10 inserts included per pack, you always have a fresh knife ready when rotating worn edges - keeping spindle moulders and profile machines running at full productivity without waiting on reorders.
