CMT Solid Carbide Knives R3 - 12x12x1.5mm, 4 Cutting Edges, 10-Pack are precision-ground reversible insert knives engineered for demanding profiling and molding work on spindle moulders, profile machines, and router tables equipped with compatible cutter head systems. Built from solid carbide material grade F1730, these square insert knives deliver a 3mm radius profile with a 35 deg. cutting angle, making them a reliable choice for edge profiling, grooving, and rabbeting across a wide range of wood-based materials. With four usable cutting edges per knife and ten knives per pack, woodworkers and production shops get exceptional value and extended uptime without frequent tool changes.

Key Features

• Solid Carbide F1730 Construction - tungsten carbide grade F1730 provides superior hardness and wear resistance, extending cutting life significantly compared to HSS alternatives when working hardwood, softwood, MDF, chipboard, and plywood.
• 4 Cutting Edges Per Insert - the square reversible design means you can rotate the knife to a fresh edge three additional times before replacing the insert, reducing downtime and lowering cost per profile cut.
• 12x12x1.5mm Insert Dimensions - a compact, standardized form factor that seats precisely in compatible cutter head pockets, maintaining consistent profile depth and alignment from the first cut to the last.
• R3 Radius Profile (3mm) - a 3mm corner radius produces smooth, clean rounded profiles and edge treatments suited for furniture components, cabinet doors, and architectural moldings.
• 35 deg. Cutting Angle - the optimized shear angle reduces cutting forces and tear-out on both face grain and end grain, producing cleaner surfaces across hardwood and engineered wood panels.
• Precision Ground to Exact Tolerances - consistent dimensional accuracy across the full 10-pack ensures uniform profile results and eliminates the need to re-adjust the cutter head when rotating or replacing inserts.
• 10-Piece Pack - a multi-unit quantity keeps production lines running with backup inserts on hand, reducing stops for procurement and ensuring job continuity during high-volume runs.

Why This Product

• Four cutting edges per knife mean one pack of 10 delivers up to 40 usable cutting edges - giving production shops long intervals between restocking and maximizing the cost efficiency of each insert purchased.
• The solid carbide F1730 grade is purpose-built for demanding materials like MDF and chipboard that quickly dull lower-grade tooling, so these inserts maintain sharp, consistent profiles through high-volume runs that would degrade softer alternatives.
• The standardized 12x12x1.5mm square format fits compatible reversible insert cutter head systems, making these a practical replacement option when worn inserts need to be swapped out quickly without special tooling or custom setup.
• The 3mm radius and 35 deg. cutting angle combination is well suited for furniture, cabinet, and millwork profiling where a refined, consistent rounded edge is required - giving craftsmen and production operators predictable, repeatable results on every pass.
