CMT Pattern Bits with Bearing - 3/4" Diameter, 1/2" Shank are precision-engineered routing bits built for template routing, flush trimming, and pattern-following work on solid hardwood, plywood, composites, and a wide range of natural and engineered wood materials. Featuring a double-edged carbide cutter mounted on a right-hand rotating body with an integrated bearing guide, these bits deliver clean, repeatable cuts in both handheld router and router table applications. The 3/4" cutting diameter and 1" cutting height make this bit well suited for dadoes, grooves, mortising, and pattern duplication tasks where accuracy and surface quality matter most.

Key Features

• Fatigue-Proof Steel Body - the bit body is constructed from special fatigue-proof steel, allowing it to handle heavy, continuous production workloads without structural failure or premature wear.
• Micrograin Carbide Cutting Edges - micrograin carbide provides a finer, denser grain structure compared to standard carbide, resulting in sharper cutting edges that stay keen longer and produce smoother finished surfaces.
• Orange Non-Stick P.T.F.E. Coating - CMT's trademark orange P.T.F.E. surface coating actively resists resin, pitch, and residue buildup, reducing friction and heat generation during cutting so the bit stays cleaner and lasts longer between sharpenings.
• 2-Flute Design - the 2-tooth geometry balances material removal rate with chip clearance, giving you efficient cutting in solid wood, plywood, MDF, laminates, and plastic without clogging.
• Bearing Guide - the integrated bearing follows a template or pattern edge precisely, enabling flush cuts and exact pattern reproduction without layout lines or freehand guesswork.
• Strict Quality Testing for Tolerance and Concentricity - every bit undergoes quality tests to guarantee cutting tolerance, balance, and concentricity, meaning reduced vibration and more consistent results across every pass.
• Right-Hand Rotation - standard right-hand rotation is compatible with the vast majority of handheld routers, router tables, and CNC routing machines, requiring no special setup or adapters.
• 1/2" Shank Diameter - the 1/2" shank provides a larger collet grip area compared to 1/4" shank bits, reducing deflection and vibration for cleaner cuts at higher feed rates.

Why This Product

• Built for production efficiency - the combination of fatigue-proof steel and micrograin carbide means this bit holds up under repetitive, high-volume routing in plywood, composites, and natural woods without the frequent edge failure that slows down production runs.
• Template and pattern routing with precision - the bearing guide allows you to follow jigs and templates accurately, making this an ideal choice for furniture makers, cabinetmakers, and woodworkers who need consistent, repeatable part profiles cut to exact dimensions.
• Cleaner cuts with less cleanup - the P.T.F.E. non-stick coating minimizes resin and pitch accumulation that causes burning and tearing, so you spend less time cleaning the bit and sanding finished parts.
• Versatile across materials and machines - with a 1/2" shank and right-hand rotation, this bit mounts directly into handheld routers, router tables, and CNC routing machines, making it a flexible addition to any shop working with solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, or plastic.
