CMT Round Nose Bit - 1" Diameter, 1/2" Radius, 1/2" Shank by CMT is a carbide-tipped routing bit engineered for cutting smooth, semi-circular coves, decorative grooves, and flowing flute profiles in wood and wood derivatives. Whether you are working on door fronts, drawer faces, or flat panels, this round nose (core box) bit gives you the control to carve consistent, repeatable decorative accents with clean edges and a refined finish. With a 1/2" shank for stable chuck engagement and a right-hand rotation design, it is suited for use in handheld routers, router tables, and CNC routing machines alike.

Key Features

• 1" Cutting Diameter with 1/2" Radius Profile - produces a full semi-circular cove in a single pass, reducing setup time and keeping decorative grooves geometrically consistent across long runs of material.
• Carbide-Tipped (HW) Flutes - hard carbide cutting edges stay sharp longer through hardwood, softwood, plywood, MDF, and composite panels, reducing the frequency of bit replacement and maintaining cut quality across extended production runs.
• 2-Flute Design - dual cutting edges balance the cut and improve surface finish quality, resulting in smoother cove walls that require less sanding or cleanup before finishing.
• 1/2" Shank - the larger shank diameter reduces vibration and deflection during routing, improving accuracy and producing cleaner, truer profiles compared to smaller shank bits under similar feed loads.
• Right-Hand Rotation - matches the standard rotation direction of virtually all handheld routers and router tables, making this bit a straightforward drop-in choice for most workshop setups.
• 1-1/4" Cutting Height - generous cutting depth allows you to rout full-profile coves in thicker stock or achieve decorative grooves at varying depths in a single setup.
• 2-7/8" Total Length - compact overall length keeps the bit well within the collet for maximum support, helping maintain stability and reducing the risk of chatter during decorative routing passes.

Why This Product

• The 1/2" radius profile and 1" cutting diameter make this bit the right choice when you need a true, geometrically accurate semi-circular cove rather than an approximated curve - ideal for fluting on cabinet doors, drawer fronts, and decorative panels.
• Carbide-tipped construction means this bit handles not just solid hardwood and softwood but also engineered materials like MDF, chipboard, and melamine without dulling prematurely - giving it versatility across mixed-material shop environments.
• The 1/2" shank provides a more secure grip in the collet than a 1/4" shank bit, reducing runout and keeping decorative grooves consistent in depth and profile even during longer routing passes on wide panels.
• With a 1-1/4" cutting height, this bit can create decorative coves in thicker stock or be lowered incrementally for shallow accent grooves - giving you flexibility to personalize surfaces with your own signature motifs across a range of project types.
