The CMT Pattern Bit with Bearing - 3/4" Diameter, 1/2" Shank (812.690.11B) is a long-series, double-fluted router bit designed for precise template routing in woodworking. Whether you are shaping cabinet components, furniture parts, signs, or toys, this carbide-tipped pattern bit pairs with a user-supplied template to replicate shapes with consistent accuracy. The top-mounted bearing rides along the edge of the template, keeping the cutting action above the workpiece and giving you a clear, unobstructed view of the cut as it progresses. Built for both professional shops and dedicated enthusiast workshops, this right-hand rotation bit handles solid hardwood, softwood, plywood, MDF, and a wide range of panel materials with confidence.

Key Features

• Double-Fluted (2-Tooth) Carbide-Tipped Design - Two cutting edges shear material cleanly on each pass, reducing tear-out and producing smooth profile edges that require minimal sanding when template routing furniture or cabinet parts.
• Top-Mounted Bearing for Template Routing - The bearing is positioned above the cutting area, so it rides along the upper face of the template. This gives you a clear sightline to the cut and allows confident, accurate freehand template work without the template obscuring the bit path below.
• Long-Series Geometry - 1 1/2" Cutting Height - A generous cutting height accommodates thicker stock and deeper profile passes, making this bit well-suited for furniture-grade pieces and multi-layer assemblies where shorter bits fall short.
• 3/4" Cutting Diameter - Provides a broad, stable cutting profile that removes material efficiently and keeps the bit tracking smoothly along template edges without deflection during extended routing sessions.
• 1/2" Shank Diameter - A full 1/2" shank seats securely in handheld routers and router tables, reducing vibration and chatter at higher feed rates compared to smaller-shank equivalents - resulting in cleaner cuts and longer tool life.
• HW (Hard Metal / Carbide) Material - Carbide-tipped construction maintains a sharp cutting edge far longer than high-speed steel, meaning fewer bit changes and more consistent results across large production runs or repeated template passes.
• Right-Hand Rotation - Compatible with the standard rotation direction of virtually all handheld routers, router tables, and CNC routing machines, so no specialized equipment is required.

Why This Product

• Template routing with an accurate, well-built pattern bit is one of the most efficient ways to duplicate curved or shaped parts repeatedly - this long-series bit's 1 1/2" cutting height means you can template-route thick stock in fewer passes, saving time on cabinetry and furniture projects.
• The top-mounted bearing placement keeps the template on top and the cutter below, which is the preferred configuration when working with bearing-guided templates on a router table or handheld router - giving you better visibility and control throughout the cut.
• At 3/4" diameter with a 1/2" shank, this bit offers the rigidity needed for stable, chatter-free cuts in hardwoods, plywood, MDF, and composite sheet goods - materials commonly used in cabinet and sign making applications.
• Carbide-tipped (HW) construction means the cutting edges stay sharp through extended use on abrasive engineered wood products like MDF and chipboard, reducing downtime spent swapping or resharpening bits during active production work.
