CMT Pattern Router Bit with Insert Knives - 3/4 in. Diameter, 1-61/64 in. Cutting Height, 1/2 in. Shank by CMT is a straight pattern routing bit engineered for flush trimming, template routing, and grooving in hardwood, boards, and sheet materials. The replaceable insert knife design makes this bit an economical choice for production environments and specialty woodworking applications where minimizing machine downtime is a priority. Whether you are running a router table or using a handheld router, this right-hand rotation bit delivers clean, consistent results in demanding routing tasks.

Key Features

• Replaceable Insert Knife Fixed by TORX Screw - the single HW (carbide) knife can be swapped out quickly without sending the bit body for resharpening, keeping your router running and reducing costly downtime between jobs.
• TORX Screw Fastening System - the TORX fastener locks the insert knife firmly in place at high operating speeds, providing a secure and repeatable knife seat for safer, more accurate cuts every time.
• Economical Insert Knife Design - replacing only the knife rather than the entire bit body lowers long-term tooling costs, making this an efficient solution for specialized or high-volume routing applications.
• 1-61/64 in. Cutting Height - the generous cutting depth allows routing, trimming, and grooving across a wide range of material thicknesses in a single pass, reducing the need for multiple setups.
• 3/4 in. Cutting Diameter - sized for precision pattern work, this diameter suits template routing and flush trimming tasks where accuracy and a clean edge profile are critical.
• 1/2 in. Shank - the 1/2 in. shank provides maximum rigidity and reduced vibration compared to smaller shanks, resulting in smoother cuts and improved bit stability during operation.
• Right-Hand Rotation - standard right-hand rotation is compatible with the vast majority of routers and router tables, ensuring straightforward setup and broad machine compatibility.
• HW (Tungsten Carbide) Knife Material - hard-wearing carbide construction maintains a sharp cutting edge longer when routing through hardwood and engineered board materials, extending the service life of each insert.

Why This Product

• Designed to minimize downtime - the insert knife system means you replace only the cutting edge, not the whole bit, so a dull or damaged knife can be swapped in seconds rather than waiting for resharpening or ordering a new bit.
• Versatile for production and specialty work - suited for routing, trimming, and grooving in boards and hardwood, this bit covers a broad range of pattern and template routing tasks with a single tool setup.
• Cost-effective tooling strategy - by purchasing replacement insert knives rather than complete bits, woodworkers and shop operators can significantly reduce per-cut tooling costs over time - a practical advantage for repeat or high-volume applications.
• Compatible with common router setups - the 1/2 in. shank fits standard 1/2 in. collets on handheld routers and router tables, making this bit easy to integrate into existing equipment without adapters or special tooling.
