CMT Solid Carbide Reversible Knives - R2 19.5x9x1.5mm - 10-Pack are precision-ground throwaway insert knives engineered for profiled rounding operations on spindle moulders, profile machines, and router tables equipped with compatible cutter heads. Built from K1920 solid carbide (tungsten carbide), these reversible knives deliver exceptional edge retention on hardwood, softwood, MDF, chipboard, and plywood - making them a reliable choice for high-volume profiling, edge rounding, and molding work. Each pack contains 10 knives, giving shops a ready supply of fresh cutting edges without downtime.

Key Features

• K1920 Solid Carbide Material - tungsten carbide construction provides superior hardness and wear resistance, extending cutting life significantly compared to high-speed steel alternatives when working dense hardwoods, abrasive sheet goods, and engineered panels.
• 4 Cutting Edges Per Knife - reversible throwaway design means each insert delivers four usable edges before replacement, maximizing value and reducing the cost per cut over time.
• R2 Radius Profile at 35 deg. Angle - the 2mm radius geometry ground at a 35 deg. cutting angle produces consistent, repeatable rounding profiles on workpiece edges, reducing sanding time and delivering clean, finished results directly off the machine.
• Precision Dimensions - 19.5mm Length x 9mm Height x 1.5mm Thickness - exact tolerances ensure secure, consistent seating in compatible cutter head pockets, preventing vibration and maintaining profile accuracy across the full run.
• 10-Piece Pack - having a full set of replacement knives on hand means production can continue without waiting for restocking, minimizing costly machine downtime in a busy shop environment.
• Profiled Rounding Reversible Insert Format - the throwaway knife system eliminates the need for knife grinding equipment and setup time, making edge profile changes faster and more consistent for operators at any skill level.

Why This Product

• Shops running high-volume edge rounding operations benefit from the four-edge reversible design - instead of stopping production to sharpen knives, operators simply rotate or swap the insert and keep cutting, dramatically reducing machine idle time.
• The K1920 solid carbide grade is matched to demanding applications in hardwood, MDF, and chipboard - materials that quickly dull softer tooling - so the knives maintain a sharp, accurate profile longer through production runs that would wear down lesser tooling grades.
• The R2 radius profile at a 35 deg. cutting angle is a standard rounding geometry used in furniture, cabinetry, and millwork, meaning these knives fit directly into common production workflows without requiring custom tooling or specialized head configurations.
• Purchasing in a 10-pack provides immediate inventory depth, so a single order covers multiple knife changes across extended production runs and keeps costs predictable without repeated small purchases.
