CMT Pattern Bit with Top Bearing, 1/4 in. Shank, 1/2 in. Diameter, 2-3/4 in. Total Length is a carbide-tipped template routing bit engineered for woodworkers who demand clean, repeatable cuts when working from a template or pattern. Designed for use with a guide template fastened securely to the workpiece, this double-fluted bit features a top-mounted bearing that rides along the template edge, keeping the cutting action fully visible so you can work with confidence and accuracy. Whether you are producing cabinet components, furniture parts, signs, or decorative projects, this CMT pattern bit opens up a wide range of creative and production routing possibilities.

Key Features

• Top-Mounted Bearing Guide - the bearing rides above the workpiece on the template surface, giving you a clear sightline to the cut and enabling precise, guided routing without obscuring your work.
• Double-Fluted (2-Tooth) Design - two cutting edges per revolution deliver a smoother finish, reduce vibration, and increase material removal efficiency compared to single-flute configurations.
• Carbide-Tipped (HW) Cutting Edges - hard carbide tips stay sharper longer than high-speed steel, reducing the frequency of bit replacement and maintaining cut quality across a full range of wood-based materials.
• 1/4 in. Shank - a compact shank diameter fits a wide variety of handheld routers and smaller router table setups, making this bit accessible to hobbyists and professionals alike.
• 1/2 in. Cutting Diameter with 1-1/4 in. Cutting Height - the combination of diameter and cutting height suits a broad range of template thicknesses and workpiece depths typical in furniture, cabinet, and sign work.
• Right-Hand Rotation - standard RH rotation is compatible with conventional router spindle direction, requiring no special setup or tooling adjustments.
• Long Series Configuration - the 2-3/4 in. total length provides additional clearance when working through thicker templates or when extra bit reach is needed for deep template routing tasks.

Why This Product

• The top-mounted bearing design keeps the bearing above the wood, giving you an unobstructed view of the routing path - ideal for intricate template work where precision matters and mistakes are costly.
• With a 1-1/4 in. cutting height, this bit handles a realistic range of workpiece thicknesses encountered in furniture and cabinet production, reducing the need for multiple passes on typical stock.
• The 1/4 in. shank makes this bit compatible with a wide selection of handheld routers and compact router tables, so no specialized equipment is required to put it to work.
• Carbide-tipped construction extends usable tool life well beyond standard steel bits, making this pattern bit a cost-effective choice for both production shops and hobbyists who want consistent results over many projects.
