CMT Round Nose Bit - 1/2" Diameter, 1/4" Radius, 1/2" Shank is a precision carbide-tipped routing bit engineered for cutting smooth, semi-circular coves and decorative grooves in wood and wood derivatives. Designed for woodworkers who want to personalize doors, drawer fronts, panels, and surface profiles, this CMT round nose bit brings clean, consistent results to fluting, veining, and ornamental routing work. The 2-flute construction and right-hand rotation make it compatible with handheld routers, router tables, and CNC routing machines.

Key Features

• Carbide-Tipped (HW) Flutes - hard metal carbide tips stay sharp through repeated cuts in solid hardwood, softwood, MDF, plywood, and other wood derivatives, reducing how often you need to stop and swap bits.
• 1/4" Radius Semi-Circular Profile - produces a precise 1/2" wide half-round cove in a single pass, ideal for consistent fluting, veining, and signature decorative accents across multiple workpieces.
• 2-Flute Design - dual cutting edges distribute the workload evenly, resulting in a smoother finish on the cut surface and reduced tearout on delicate or figured wood.
• Right-Hand Rotation - standard RH rotation matches the spindle direction of virtually all handheld routers and router tables, so the bit installs and runs without any special setup.
• 1/2" Shank Diameter - a full 1/2" shank seats securely in the collet, minimizing vibration and chatter during decorative routing passes and improving cut quality.
• 1 1/4" Cutting Height - generous cutting depth allows you to rout decorative coves in a single controlled pass through thicker stock without needing multiple height adjustments.
• 2 7/8" Total Length - the overall length provides enough clearance above the collet for use in both router table setups and handheld router applications without interference.

Why This Product

• The 1/4" radius profile delivers a clean, symmetrical 1/2" cove - a size commonly used for door and drawer front fluting - making this bit a practical choice for cabinet shop production as well as one-off custom work.
• Carbide-tipped construction in the HW (hard metal) grade handles the full range of wood-based materials - from solid hardwood to MDF and chipboard - so you can switch between substrates without changing bits.
• The 1/2" shank reduces runout and vibration compared to smaller shank sizes, which translates directly into cleaner groove edges and less sanding time after routing.
• With a 1 1/4" cutting height and 2 7/8" total length, this bit is proportioned to handle real workpiece thicknesses in a single setup, saving time on multi-pass adjustments when routing decorative panel profiles.
