CMT Round Nose Bit - 2 in. Diameter, 1 in. Radius, 1/2 in. Shank is a professional-grade carbide-tipped routing bit designed to cut smooth, semi-circular coves and decorative grooves with precision. Whether you are fluting columns, veining panels, or carving signature decorative accents into doors and drawer fronts, this round nose (core box) bit delivers clean, consistent results in solid hardwood, softwood, and wood derivatives alike. With a full 2 in. cutting diameter and a true 1 in. radius, it is purpose-built for woodworkers and CNC operators who demand repeatable, high-quality profile work on any wood surface.

Key Features

• 2 in. Cutting Diameter with 1 in. Radius - produces a wide, perfectly symmetrical semi-circular cove in a single pass, reducing the need for multiple setups or passes when routing decorative grooves and flutes.
• Carbide-Tipped (HW) Cutting Flutes - hard carbide material resists wear and maintains a sharp cutting edge through extended use in hardwoods, softwoods, plywood, MDF, chipboard, and other wood derivatives.
• 2-Flute Design - dual cutting edges improve chip evacuation, reduce heat buildup at the cutting zone, and deliver a smoother surface finish in both freehand and table-mounted routing applications.
• 1/2 in. Shank Diameter - the larger shank diameter provides superior bit stability and reduced vibration compared to smaller shanks, making it compatible with full-size handheld routers, router tables, and CNC routing machines.
• Right-Hand Rotation (RH) - matches the standard spindle rotation direction of conventional routers, ensuring safe, predictable cutting behavior without special setup requirements.
• 1 1/4 in. Cutting Height - generous cutting depth allows for coves and grooves with meaningful visual depth, making it suitable for decorative panel work and architectural millwork details.
• 2 3/4 in. Overall Length - compact total length keeps the bit rigid and reduces deflection during cutting, contributing to cleaner groove profiles and more accurate results.

Why This Product

• The full 1 in. radius profile means you can rout a complete 2 in. wide semi-circular cove in a single pass - ideal for fluting, veining, and decorative surface work on doors, drawer fronts, and panels without repositioning.
• The carbide-tipped (HW) construction maintains cutting sharpness through demanding production runs in hardwoods and engineered wood products like MDF and chipboard, reducing tool change frequency and downtime.
• The 1/2 in. shank is compatible with a wide range of full-size handheld routers, router tables, and CNC machines, giving this bit broad versatility across shop setups and production environments.
• The 2-flute geometry promotes clean chip clearance and reduced heat at the cut, which directly translates to smoother cove surfaces that require less sanding and finishing time.
