CMT Pattern Router Bit with Insert Knives - 1-1/8 in. Cutting Diameter, 1-61/64 in. Cutting Height, 1/2 in. Shank by CMT is a professional-grade straight router bit designed for pattern routing, template routing, flush trimming, and grooving in a wide range of materials. Featuring two replaceable hardwood-grade insert knives secured with TORX screws, this bit delivers consistent, clean cuts in hardwood, softwood, plywood, MDF, chipboard, laminates, and plastics - making it a versatile choice for both bench-top router tables and handheld routing operations.

Key Features

• Replaceable Insert Knives with TORX Screw Fastening - Each knife is secured by a precision TORX screw, allowing quick knife swaps without removing the bit from the collet, which means less downtime and more time cutting.
• Two-Sided Reversible Insert Knives - Each knife has two usable cutting edges that can be flipped for a second fresh edge, reducing the frequency of knife replacement and lowering tooling cost over time.
• Resharpenagle Knives (up to 3 times) - The insert knives can be resharpened up to 3 times, extending the useful life of each knife and providing an economical long-term solution for high-volume routing applications.
• Hardwood-Grade Carbide Material (HW) - Constructed from hardwood-grade carbide, the insert knives maintain a sharp cutting edge through demanding passes in dense hardwood, MDF, and composite board materials.
• 1-61/64 in. Cutting Height - The generous cutting height allows for deep single-pass cuts in thick stock, reducing the need for multiple incremental passes when routing full-thickness boards.
• 1/2 in. Shank Diameter - The 1/2 in. shank provides maximum rigidity and reduced vibration during high-speed routing, resulting in smoother cuts and improved surface finish.
• Right-Hand Rotation - Standard right-hand rotation is compatible with the vast majority of hand routers and router tables, ensuring broad machine compatibility without adapters or special setup.
• 2-Knife Configuration - The two-flute design balances cutting load evenly, promoting smooth chip evacuation and a clean finish on wood, laminate, and plastic workpieces.

Why This Product

• Low-downtime knife replacement - Because the insert knives are fixed by a single TORX screw, they can be rotated or replaced in minutes, making this bit an economical solution for production environments or specialized applications where stopping work is costly.
• Cost-effective alternative to solid carbide bits - With reversible, resharpenable insert knives, this pattern router bit spreads tooling cost across multiple cutting edges and resharpening cycles rather than requiring full bit replacement when edges dull.
• Handles a broad range of workpiece materials - From dense hardwood and softwood to MDF, chipboard, laminates, and plastics, this bit is suited for shops and tradespeople who route multiple material types without swapping tool sets.
• 1/2 in. shank for router table and handheld use - The 1/2 in. shank diameter is compatible with both router tables and hand routers equipped with a 1/2 in. collet, giving operators flexibility in how and where the bit is deployed.
