CMT Pattern and Flush Trim Router Bit with Insert Knives - 3/4" Diameter, 2-3/8" Cutting Height, 1/2" Shank by CMT is a professional-grade routing tool engineered for precision flush trimming and pattern routing operations. Combining the functionality of a flush trim bit and a pattern routing bit into a single tool, this bit features replaceable two-sided insert knives secured with Torx screws, along with top and bottom ball bearing guides that deliver exceptional stability when working against templates or straight edges. Whether you are trimming laminates flush to a substrate, routing shapes with a template, or finishing edges on hardwood and MDF, this right-hand rotation bit is built for accurate, repeatable results across a wide range of materials.

Key Features

• Dual Ball Bearing Guides (top and bottom) - both a top-mounted and bottom-mounted bearing allow the bit to function as either a flush trim bit or a pattern bit depending on your setup, giving you maximum versatility without changing tools.
• Two-Sided Reversible Insert Knives - each knife is sharpened on both sides, so when one cutting edge dulls, simply flip the knife to expose a fresh edge, reducing downtime and extending the usable life of each insert.
• Torx Screw Fastening - insert knives are secured with Torx screws that resist cam-out under high-speed routing conditions, keeping the knives firmly locked in position for safer and more consistent cuts.
• 2-3/8" Cutting Height - the extra-long cutting length accommodates thicker stock and deep pattern cuts in a single pass, reducing the need for multiple setups or stepped passes.
• Hard Metal (HW) Knife Material - carbide-tipped insert knives hold a sharp edge longer than standard steel, maintaining cut quality through extended production runs on hardwood, softwood, plywood, MDF, chipboard, laminates, and plastics.
• 1/2" Shank Diameter - the robust 1/2" shank provides a secure, low-vibration fit in router tables and hand routers equipped with 1/2" collets, improving cut accuracy and surface finish.
• Right-Hand Rotation - standard right-hand rotation is compatible with the vast majority of routers and router tables, simplifying setup and tool selection.
• 4-3/4" Total Length - the overall length is sized to reach through standard workpiece thicknesses while still clearing the router base, supporting both table-mounted and handheld use.

Why This Product

• One bit, two guide configurations - the top-and-bottom ball bearing design means you can follow a template placed above or below the workpiece without swapping bits, saving setup time on complex template routing and flush trimming jobs.
• Lower long-term tooling cost - because each insert knife has two usable cutting edges and can be flipped rather than replaced immediately, you get more cuts per insert and reduce the frequency of purchasing new blades.
• Consistent results on demanding materials - the 2-3/8" cutting height and hard metal knife construction are suited to routing full-thickness hardwood panels, MDF, plywood, laminates, and plastics without sacrificing edge quality or requiring multiple passes.
• Stable, vibration-free performance - the combination of a 1/2" shank and Torx-locked insert knives minimizes runout and chatter, which translates directly to smoother finished edges and more accurate pattern reproductions.
