CMT Pattern Bit with Bearing - 9/16 in. Diameter, 1/4 in. Shank is a precision-ground, bearing-guided flush trimming and template routing bit engineered for consistent, repeatable cuts in solid hardwood, softwood, plywood, composites, and natural woods. Built from special fatigue-proof steel and micrograin carbide, this 2-flute straight bit handles heavy production workloads while the top-mounted bearing keeps your work referenced accurately against a template or guide edge - making it a dependable choice for pattern routing, flush trimming, and joinery work on handheld routers, router tables, and CNC routing machines alike.

Key Features

• Micrograin Carbide Cutting Edges (HW) - harder and more wear-resistant than standard carbide, these edges stay sharp longer through demanding production runs in plywood, composites, and solid wood, reducing changeover downtime.
• Fatigue-Proof Steel Body - the body resists stress fractures and deflection under heavy workloads, maintaining dimensional accuracy cut after cut so your routed profiles stay true to the template.
• Orange Non-Stick P.T.F.E. Coating - CMT's trademark surface treatment prevents resin, pitch, and adhesive residue from bonding to the bit, making cleanup faster and reducing heat buildup that can scorch workpieces or degrade cutting edges.
• Bearing Guide Included - the integrated bearing rides along a template or straightedge, allowing accurate pattern routing and flush trimming without additional fences or jigs, saving setup time.
• 2-Flute (2-Tooth) Design - dual cutting edges provide a balanced cut with a smooth surface finish on a wide range of materials including MDF, laminates, melamine, and plastic, reducing tearout and post-routing cleanup.
• Right-Hand Rotation - standard RH rotation is compatible with virtually all handheld routers, router tables, and CNC routing machines, ensuring broad machine compatibility without adapters.
• Strict Quality Tolerance Testing - every bit is subject to rigorous quality tests verifying cutting tolerance, balance, and concentricity, so you get consistent, vibration-free performance from the first pass.

Why This Product

• The bearing guide eliminates the need for a separate fence when pattern routing or flush trimming, making this bit a practical solution for woodworkers and production shops that rely on templates for repeatable part shapes.
• With a 9/16 in. cutting height matching the 9/16 in. diameter, this short-series bit is well-suited to trim and pattern work where a compact profile reduces chatter and improves control compared to longer bits of the same diameter.
• The combination of micrograin carbide and the P.T.F.E. non-stick coating addresses two common production pain points at once - edge dulling and resin buildup - helping maintain cut quality over longer runs in natural woods and composites.
• At a 1/4 in. shank diameter, this bit fits a wide range of compact routers and trim routers in addition to full-size machines, giving hobbyists and production shops alike flexibility in which tool they reach for.
