CMT Solid Carbide Knives R5 19.5x9x1.5mm - 10-Pack are precision-ground, reversible throwaway insert knives engineered for profiled rounding operations on spindle moulders, profile machines, and compatible insert cutter head systems. Manufactured from K1920 tungsten carbide, each knife in this 10-piece pack delivers four usable cutting edges and a 5mm radius profile at a 35 deg. cutting angle, making them a reliable choice for craftsmen and production shops demanding consistent profile quality in hardwood, softwood, MDF, and chipboard applications.

Key Features

• K1920 Solid Carbide Material - tungsten carbide construction provides superior hardness and wear resistance compared to high-speed steel, extending tool life significantly when working with abrasive materials like MDF and chipboard.
• Reversible Throwaway Knife Design with 4 Cutting Edges - rotating to a fresh edge when one dulls means you get four times the cutting life from each knife, reducing downtime and lowering the cost per cut over a production run.
• R5 Radius Profile at a 35 deg. Cutting Angle - the precisely formed 5mm radius and engineered cutting angle deliver a clean, repeatable rounding profile on workpiece edges, reducing the need for secondary sanding or finishing passes.
• Compact Dimensions: 19.5x9x1.5mm - the exact knife geometry (19.5mm length, 9mm height, 1.5mm thickness) ensures a secure, snug seat in compatible cutter head pockets, minimizing vibration and chatter for a smooth cut surface.
• 2 Teeth Per Knife - dual-tooth geometry balances chip load across the cutting edge, contributing to a smoother finish and more consistent feed rate performance.
• 10-Piece Pack - stocking multiple knives in a single purchase keeps production running without interruption, giving shops a ready supply of fresh edges on hand.
• Precision Ground to Exact Tolerances - tight dimensional consistency from knife to knife means each replacement insert performs identically, maintaining profile accuracy across long production runs without re-adjustment.

Why This Product

• Four cutting edges per knife mean shops get maximum value from every insert - when one edge wears, simply index to the next rather than stopping to replace the tool, keeping production moving efficiently.
• The K1920 carbide grade is specifically suited for profiling operations on hardwood, softwood, MDF, and chipboard, giving woodworking shops a single versatile insert knife that handles a broad range of common materials without requiring grade changes.
• Precise 19.5x9x1.5mm dimensions and the 5mm radius profile are matched to the HW-K1920 insert system, ensuring a direct, drop-in fit for compatible cutter heads without modification or shimming.
• Buying in a 10-piece pack ensures a consistent supply of matched, identically ground knives, so every edge change restores the same profile geometry and finish quality - critical for repeat orders and batch production work.
