CMT Solid Carbide Reversible Insert Knives (4/30 deg.) 14x14x2mm - 10-Piece Pack are precision-ground throwaway indexable knives engineered for spindle moulders, profile machines, and compatible insert shaper cutter head systems. Manufactured from K2250 grade solid carbide, these knives deliver lasting performance across demanding cuts in hardwood, softwood, MDF, chipboard, and plywood. Each knife features four usable cutting edges at a 30 deg. bevel angle, meaning when one edge dulls you simply rotate to a fresh edge - maximizing value and reducing downtime on profiling, grooving, rabbeting, and jointing operations. The reversible square geometry (14mm x 14mm x 2mm) follows the standard K192 indexable knife format, making these a reliable replacement insert for compatible cutter head systems.

Key Features

• K2250 Solid Carbide Material - tungsten carbide grade K2250 holds a sharper edge longer than high-speed steel, reducing the frequency of insert changes during prolonged profiling runs in hardwood or engineered panel materials.
• Four Cutting Edges per Knife - the reversible square design provides four usable 30 deg. bevel edges per insert, so you get up to four times the cutting life from each knife before disposal, lowering cost per foot of cut profile.
• 30 deg. Bevel Angle - the 30 deg. relief geometry balances cutting efficiency with edge stability, supporting clean, consistent profiles across a range of wood species and composite board materials.
• Standard K192 Indexable Format (14x14x2mm) - the square 14mm x 14mm footprint with 2mm thickness and 6.4mm bore diameter conforms to the standard reversible throwaway knife format, ensuring straightforward compatibility with insert cutter heads designed for this geometry.
• 10-Piece Pack Quantity - ten knives per pack means you have an on-hand supply of inserts ready for quick edge rotations or replacements, keeping production moving without waiting on individual replacement orders.
• Precision Ground Dimensions - each knife is ground to exact 14x14x2mm tolerances, ensuring consistent seating in cutter head pockets and repeatable profile accuracy across a full production run.

Why This Product

• Solid carbide construction in K2250 grade makes these inserts a practical upgrade for woodworkers cutting abrasive materials like MDF and chipboard, where softer tooling dulls quickly and causes profile inconsistency.
• The four-edge reversible design means each knife in this 10-piece pack effectively provides the equivalent of 40 fresh cutting edges - a cost-efficient approach to insert tooling for production shops and busy millwork operations.
• The standard 14x14x2mm K192 throwaway knife format is widely used across compatible insert shaper cutter head systems, making these a straightforward drop-in replacement without retooling or special setup.
• Stocking a 10-piece pack reduces the risk of production stoppages from unexpected edge wear - having inserts on hand allows immediate rotation to a sharp edge and keeps profiling, grooving, and rabbeting operations on schedule.
