CMT Round Nose Bit - 1 1/2" Diameter, 3/4" Radius, 1/2" Shank by CMT is a precision carbide-tipped routing bit engineered for creating smooth, semi-circular coves, decorative grooves, and elegant fluted profiles in wood and wood-based materials. Whether you are personalizing cabinet doors, drawer fronts, or decorative panels, this round nose bit - also commonly called a core box bit - delivers clean, accurate results in solid hardwood, softwood, MDF, and a wide range of wood derivatives. With a right-hand rotation and a 2-flute design tipped with HW (hard metal) carbide, it brings professional-grade decorative routing capability to handheld routers, router tables, and CNC machines alike.

Key Features

• 1 1/2" Cutting Diameter with 3/4" Radius - produces a full, generous semi-circular cove profile in a single pass, giving decorative grooves and fluting a smooth, balanced appearance without multiple setups.
• Carbide-Tipped (HW) Flutes - hard metal carbide tips maintain a sharp cutting edge longer than high-speed steel alternatives, reducing the frequency of bit changes and keeping cuts clean through hardwood, softwood, MDF, plywood, and other wood derivatives.
• 2-Flute Design - dual flutes balance cutting load and chip evacuation, resulting in a smoother finish on decorative surfaces and reducing tear-out on delicate workpieces.
• 1/2" Shank - the larger shank diameter provides greater rigidity and reduced vibration compared to smaller shanks, which translates to more accurate cuts and a finer surface finish on coves and veining work.
• Right-Hand Rotation (RH) - compatible with the standard rotation direction of virtually all handheld routers, router tables, and CNC routing machines, making setup straightforward and safe.
• 1 1/4" Cutting Height - sufficient depth capacity to rout full-profile flutes and decorative grooves in a single pass on most door and panel profiles, minimizing the need for repeated shallow passes.
• 2 3/4" Total Length - a compact overall length keeps the bit stable in the collet while still providing enough reach for common decorative routing applications.

Why This Product

• If you need to add a signature decorative motif - such as fluting, veining, or rounded coves - to cabinet doors, drawer fronts, or wall panels, this bit cuts the full 3/4" radius profile cleanly in a single pass, saving time and setup effort.
• The 1/2" shank makes this bit compatible with mid-range and professional routers, providing the stability needed for consistent, repeatable decorative cuts across multiple workpieces in a production or shop environment.
• With carbide-tipped (HW) cutting flutes, the bit maintains its edge through a wide variety of materials - from solid hardwoods to MDF and plywood - making it a versatile choice for shops that work with multiple wood species and wood-composite substrates.
• The 2-flute geometry and right-hand rotation are optimized for use on handheld routers, router tables, and CNC routing machines, giving woodworkers and fabricators flexibility in how and where they use the bit.
