CMT Pattern Bit with Bearing - 1/2 in. Diameter, 1/4 in. Shank is a precision-ground, carbide-tipped flush trim and template routing bit engineered for accurate pattern duplication in solid hardwood, softwood, plywood, composites, and natural woods. Built by CMT for high-volume production environments as well as shop and hobbyist use, this straight bit short series router bit features a top-mounted bearing guide that follows templates and patterns exactly, delivering clean, repeatable cuts with minimal tearout. Whether you are cutting dadoes, grooves, or flush-trimming workpieces to a template, this 2-tooth right-hand rotation bit gives you the control and cutting consistency needed for demanding joinery and production work.

Key Features

• Micrograin Carbide Cutting Edges - micrograin carbide is denser and harder than standard carbide, holding a sharper edge longer through heavy production use in plywood, composites, and natural woods, reducing the frequency of sharpening or replacement.
• Fatigue-Proof Steel Body - the body is machined from special fatigue-proof steel that resists flexing and deformation under load, maintaining concentricity and balance even during extended, high-intensity routing sessions.
• CMT Orange Shield Non-Stick Coating - the trademark orange P.T.F.E. non-stick surface coating prevents resin, pitch, and other residue from adhering to the bit, which reduces heat buildup, keeps cuts cleaner, and protects against corrosion to extend tool life.
• Bearing Guide Included - the integrated bearing allows the bit to ride precisely along a template or pattern edge, making flush trimming and template routing repeatable and accurate without additional jigs or setups.
• 2-Flute Right-Hand Rotation - two cutting edges in right-hand rotation provide a balanced chip load and smooth surface finish, suitable for handheld routers, router tables, and CNC routing machines.
• Strict Quality Testing - every bit is tested for cutting tolerance, balance, and concentricity before leaving the factory, ensuring consistent performance and dimensional accuracy from the first cut.
• 1/4 in. Shank - the 1/4 in. shank fits a wide range of compact routers and standard collets, making this bit compatible with entry-level and professional handheld routers alike.

Why This Product

• The bearing-guided design eliminates the guesswork in template routing - simply follow your pattern and the bit delivers a flush, consistent cut every time, making it ideal for production runs, jig-based workflows, and repeatable joinery like rabbets and dadoes.
• The combination of micrograin carbide and fatigue-proof steel means this bit is built for demanding work in plywood, laminates, melamine, and composites without sacrificing edge sharpness or concentricity under load.
• The P.T.F.E. non-stick coating actively prevents pitch and resin accumulation during cuts in sticky or resinous woods, keeping the bit running cleaner and cooler and reducing downtime for cleaning between operations.
• At 3/4 in. cutting height and 2 1/4 in. total length, this short-series pattern bit is compact enough for handheld router use while still providing sufficient depth capacity for common dado, rabbet, and flush-trim applications.
