CMT Flush Trim Bit with Insert Knives - 3/4" Diameter, 1 3/16" Cutting Height, 1/2" Shank is a professional-grade router bit engineered for precise flush trimming of laminates, edge banding, veneers, and solid wood materials. Built around two replaceable insert knives secured with special Torx screws, this right-hand rotation bit delivers clean, accurate cuts while keeping long-term tooling costs low through knife replacement rather than full-bit replacement. Whether used in a hand router or mounted in a router table, this 1/2" shank bit provides the rigidity and cutting performance that demanding woodworking and cabinetry applications require.

Key Features

• Two Replaceable Insert Knives - knives can be swapped out when dull rather than replacing the entire bit body, reducing tooling cost and downtime on the job.
• Torx Screw Fastening - special Torx screws lock the insert knives firmly in place during high-speed routing, providing secure, vibration-resistant clamping for safer and more consistent cuts.
• 3/4" Cutting Diameter with 1 3/16" Cutting Height - provides generous material contact in a single pass, making this bit well-suited for flush trimming thick laminates, edge banding, and pattern work without requiring multiple setups.
• 1/2" Shank Diameter - the full 1/2" shank seats deeply in the collet, minimizing runout and deflection for smoother surface finishes when trimming wood, plywood, MDF, and plastic materials.
• Right-Hand Rotation - compatible with standard router configurations, ensuring straightforward setup on both handheld and table-mounted routers without special adapters.
• Hardwood-Grade Carbide Insert Material - HW-grade carbide knives maintain a sharp cutting edge through extended use across a wide range of wood composites and plastics, reducing the frequency of knife changes.
• Ball Bearing Guide - the 657.1-type guided design rides along a template or reference surface to produce precise, repeatable flush trim and pattern routing results without the need for fences or stops.

Why This Product

• The replaceable insert knife system means the bit body stays in service indefinitely - only the knives are replaced, making this a cost-effective long-term solution for shops that do frequent flush trimming and pattern routing work.
• At 3/4" diameter and 1 3/16" cutting height, this bit handles a practical range of material thicknesses in one pass, reducing setup time when trimming edge banding, laminates, or veneers flush to a substrate.
• The 1/2" shank provides a secure, low-vibration fit in 1/2" collet routers and router tables, translating directly into cleaner cut edges and more consistent results across hardwood, softwood, plywood, MDF, chipboard, and plastics.
• The Torx screw clamping system keeps insert knives locked under the high rotational forces of router operation, giving the operator confidence that the cutting geometry stays consistent throughout the cut.
