CMT Solid Carbide Knives R1.5 - 4 Cutting Edges, 12x12x1.5mm, 10-Pack are precision-ground reversible insert knives engineered for demanding profiling and molding operations on spindle moulders, profile machines, and router tables equipped with compatible cutter heads. Manufactured from solid carbide material grade F1730, these 1.5mm radius insert knives deliver long service life and consistent profile accuracy across hardwood, softwood, MDF, chipboard, and plywood. With four usable cutting edges per insert and ten pieces per pack, this CMT offering gives woodworking professionals and production shops a cost-effective supply of high-performance carbide inserts ready for edge profiling, grooving, rabbeting, jointing, and general molding work.

Key Features

• Solid carbide F1730 material construction - tungsten carbide grade F1730 maintains hardness and edge retention far longer than high-speed steel, reducing downtime for insert changes during high-volume runs on hardwood and engineered wood materials.
• Four cutting edges per insert - rotate the knife up to four times before replacement, multiplying usable life and lowering the cost per linear foot of finished profile compared to single-edge inserts.
• R1.5mm radius profile geometry - delivers a precise, repeatable 1.5mm radius on every pass, ensuring consistent profile quality across a full production run without re-setup between inserts.
• 35 deg. cutting angle - the engineered rake geometry promotes clean shearing action through hardwood and MDF alike, reducing tearout and leaving a smoother surface that requires less sanding.
• Compact 12x12x1.5mm insert size - the square insert format seats securely in compatible cutter heads, and the uniform 12mm side dimensions simplify indexing and help maintain consistent cutting depth across all four edges.
• 10-piece pack quantity - provides a ready shop supply of matched inserts, keeping production moving without frequent reordering interruptions.

Why This Product

• The four-edge reversible design means each insert delivers up to four times the working life of a non-reversible knife - a practical advantage for shops running continuous profiling operations where insert changeover time directly affects output.
• Solid carbide F1730 construction handles the abrasive demands of MDF, chipboard, and hardwood without the rapid dulling associated with softer tooling materials, keeping profiles sharp and dimensionally accurate across long production runs.
• The 1.5mm radius geometry is ground to exact tolerances, so every insert in the 10-pack produces the same finished profile - critical for matching parts across batches in furniture, cabinetry, and millwork applications.
• A 35 deg. cutting angle optimized for insert knives of this geometry reduces cutting forces on the workpiece, making these inserts a sound choice for edge profiling and rabbeting on delicate or thin workpieces where tearout control matters.
