CMT Solid Carbide Reversible Knives - R6.4 Radius, 24x12x1.5mm, 10-Piece Pack are precision-ground throwaway insert knives engineered for profiled rounding cuts on spindle moulders, profile machines, and compatible cutter head systems. Built from K1920 grade tungsten carbide, these reversible knives deliver consistent radius profiling and extended tool life in hardwood, softwood, MDF, chipboard, and plywood applications. Each knife features 4 usable cutting edges and a 35 deg. cutting angle, making them a practical choice for production shops and skilled woodworkers who demand repeatable edge quality without frequent regrinding.

Key Features

• K1920 Solid Carbide Material - a premium tungsten carbide grade that holds a sharp edge significantly longer than high-speed steel, reducing downtime and replacement frequency in demanding profiling applications.
• 4 Cutting Edges Per Knife - reversible throwaway design means you rotate or flip the insert to expose a fresh cutting edge when one dulls, multiplying usable life and lowering the cost per cut.
• R6.4mm Radius Profile - precision-ground to an exact 6.4mm rounding radius so every pass produces a consistent, repeatable profile across the full workpiece run.
• 35 deg. Cutting Angle - optimized rake geometry reduces cutting resistance and produces a cleaner surface finish on both solid wood and engineered panels.
• 24x12x1.5mm Knife Dimensions - compact throwaway insert format fits the cutter head body precisely, maintaining balanced rotation and vibration-free cutting performance.
• 10-Piece Pack - stocked in volume to keep production running with spare inserts on hand, minimizing mid-run stoppages for tool changes.

Why This Product

• The reversible 4-edge design means a single pack of 10 knives provides up to 40 fresh cutting edges - significantly extending the value of each purchase compared to single-edge insert knives.
• The K1920 carbide grade and precision-ground 6.4mm radius profile eliminate the need for regrinding, making these throwaway knives ideal for shops that want consistent profile accuracy without the cost of a dedicated sharpening setup.
• At 1.5mm thickness and 24mm length, these inserts are sized to seat securely in compatible cutter head bodies, supporting vibration-free operation and uniform profile depth across long production runs.
• The 35 deg. cutting angle suits a broad range of materials - from hardwood and softwood to MDF and chipboard - making this a versatile insert choice for shops that run mixed-material profiling work.
