The CMT Contractor Round Nose Bit is a precision-crafted routing bit designed for professional sign makers, cabinet makers, and woodworkers who demand clean, smooth semi-circular coves and decorative grooves. With a 3/4 in. cutting diameter, 1/2 in. cutting height, and a 3/8 in. radius, this round nose bit is ideally suited for fluting columns, veining panel surfaces, routing decorative cabinet doors, and adding creative detail to drawer fronts and signs. The 1/4 in. shank fits a wide range of handheld routers and router tables, making it a versatile addition to any woodworking shop. Two carbide-tipped cutting edges deliver a smooth, professional finish in wood and wood composite materials, while the right-hand rotation ensures compatibility with standard router operation.

Key Features

• 3/4 in. Cutting Diameter with 3/8 in. Radius - produces consistently proportioned semi-circular profiles ideal for decorative fluting, cove routing, and veining in a single pass.
• 1/2 in. Cutting Height - provides sufficient depth capacity for creating full, well-defined grooves and decorative details on cabinet doors, drawer fronts, and sign faces.
• Two Carbide-Tipped Cutting Edges (HW Material) - hard-wearing carbide tips maintain sharpness longer than high-speed steel, delivering smooth cuts in solid wood, plywood, and wood composite products with less tearout.
• 1/4 in. Shank - fits a broad range of standard handheld routers and router tables, making this bit accessible for both professional shops and home workshops.
• Right-Hand Rotation - matches the standard direction of virtually all routers, ensuring safe and accurate operation without special setup requirements.
• 1 13/16 in. Total Length - compact overall length contributes to bit stability and reduced vibration during operation, supporting cleaner, more controlled cuts.
• Contractor-Grade Construction - built to the demands of professional sign and cabinet makers who require reliable, repeatable performance across high-volume routing tasks.

Why This Product

• Purpose-built for decorative woodworking applications - this round nose bit is specifically designed for sign making, cabinet door detailing, and drawer front decoration, giving woodworkers a dedicated tool for these common professional tasks rather than a general-purpose compromise.
• Carbide-tipped cutting edges mean the bit stays sharp through extended production runs in solid hardwood, softwood, and wood composite materials, reducing downtime for bit changes and delivering consistent groove quality from the first cut to the last.
• The combination of 3/4 in. diameter and 3/8 in. radius provides a well-proportioned semi-circular profile that suits a wide variety of decorative routing projects, from subtle veining to prominent fluted columns and panel details.
• The 1/4 in. shank makes this bit compatible with a wide selection of routers already found in professional and hobbyist shops, so there is no need for specialized tooling or adapters to get started.
