CMT Round Nose Bit - 3/4" Diameter, 3/8" Radius, 1/2" Shank by CMT is a precision carbide-tipped routing bit engineered for creating smooth, semi-circular coves, decorative grooves, and fluted accents in a wide range of wood and wood-based materials. Whether you are personalizing doors, drawer fronts, wall panels, or any flat surface, this round nose (core box) bit delivers clean, consistent results that reflect your own signature style. With a 2-flute design in industrial-grade carbide, it performs reliably on handheld routers, router tables, and CNC routing machines alike.

Key Features

• 3/4" Cutting Diameter with 3/8" Radius - produces a precisely proportioned semi-circular profile ideal for fluting, veining, and decorative cove work, giving woodworkers clean, repeatable results every pass.
• 1 1/4" Cutting Height - allows deeper passes through thicker stock in a single setup, reducing the need for multiple repositioning steps and saving time on larger panels or door fronts.
• Carbide-Tipped (HW) Flutes - hard carbide cutting edges stay sharp longer than high-speed steel alternatives, maintaining edge quality through extended production runs in hardwood, softwood, plywood, MDF, and composite materials.
• 2-Flute Design - dual cutting edges balance the bit during rotation for smoother chip evacuation, reduced vibration, and a cleaner finished surface requiring less sanding.
• 1/2" Shank Diameter - the larger shank provides greater rigidity and reduced chatter compared to 1/4" shank bits, improving accuracy and surface quality especially in harder materials or at higher feed rates.
• Right-Hand Rotation - compatible with standard right-hand router collets used on virtually all handheld routers, router tables, and CNC machines, ensuring straightforward drop-in compatibility.
• 2 7/8" Total Length - compact overall profile keeps the bit well-supported in the collet while still providing ample reach for most decorative routing applications.

Why This Product

• Woodworkers who want to add distinctive decorative detail - flutes, veining, or rounded coves - to doors, drawer fronts, or panels will find this bit produces the smooth 3/8" radius profile needed without specialty tooling.
• The carbide-tipped construction handles a broad material range including solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastics, making it a versatile single-bit solution across many project types.
• The 1/2" shank is the preferred choice for router table and CNC setups where rigidity matters - it minimizes deflection and helps maintain the tight tolerances required for repeatable decorative profiles across multiple workpieces.
• At 2 7/8" total length with a 1 1/4" cutting height, this bit is sized appropriately for both freehand decorative routing and guided table work, giving users flexibility across different workflow setups without swapping tools.
