CMT Round Nose Bit with Bearing - 3/4 in. Diameter, 3/8 in. Radius, 1/2 in. Shank by CMT is a precision carbide-tipped routing bit designed to cut smooth, semi-circular coves and decorative grooves with consistent, repeatable results. Whether you are fluting door panels, veining drawer fronts, or adding a signature decorative motif to any wood surface, this round nose (core box) bit delivers clean, accurate profiles in solid hardwood, softwood, plywood, MDF, and a wide range of wood derivatives. The integrated bearing guide keeps the bit tracking true along your workpiece edge, making it equally at home in a handheld router, a router table setup, or a CNC routing machine.

Key Features

• 3/4 in. cutting diameter with 3/8 in. radius - produces a precise half-round profile in a single pass, eliminating the need for multiple setups or profile adjustments when routing decorative coves and flutes.
• Carbide-tipped (HW) cutting flutes - industrial-grade carbide holds a sharp edge longer than high-speed steel, reducing the frequency of resharpening and keeping cuts clean through hardwood, softwood, plywood, MDF, and composite materials.
• 2-flute design - two cutting edges balance chip removal with surface finish quality, producing smoother groove walls and reducing tearout on sensitive wood grains and laminates.
• Integrated bearing guide - the bearing follows the workpiece edge or a template, keeping the cove depth and profile consistent along the full length of any cut without requiring a fence or additional guides.
• 1/2 in. shank - a full 1/2 in. shank provides maximum rigidity in the collet, minimizing vibration and chatter during decorative routing passes for a cleaner, more accurate finished profile.
• Right-hand (RH) rotation - standard right-hand rotation is compatible with virtually all handheld routers, router tables, and CNC spindles, so no special toolholding is required.
• 1 1/4 in. cutting height - generous flute length allows a full decorative cove to be routed in materials up to 1 1/4 in. thick, accommodating most panel and door-front thicknesses in a single setup.
• 2 7/8 in. total length - compact overall length keeps the bit stable in the collet while still providing enough clearance for use in enclosed router table guards and standard collet housings.

Why This Product

• The bearing guide makes this bit ideal for freehand edge routing without a fence - simply follow the natural edge of a panel or a routed template to produce perfectly matched coves across multiple workpieces, saving setup time on repetitive decorative projects.
• The 3/8 in. radius is a widely used profile for fluting on doors, drawer fronts, and furniture panels - it is proportioned to complement standard cabinet door styles without looking over-scaled or too subtle, making it a practical choice for both furniture makers and cabinet shops.
• With a 1/2 in. shank and a 2-flute carbide-tipped configuration, this bit is built for sustained use in production environments as well as one-off custom work - the shank size reduces runout and the carbide grade (HW) is suited for continuous cuts through hardwoods and sheet goods alike.
• Compatibility with handheld routers, router tables, and CNC machines means this single bit can move between workflow stages - from hand-guided edge work on a job site to table-mounted production routing - without requiring a different tool for each context.
