CMT Round Nose Bit with Bearing - 1/2" Diameter, 1/4" Radius, 1/4" Shank by CMT is a precision carbide-tipped routing bit designed for creating smooth, semi-circular coves, decorative fluting, and veining profiles in wood and wood derivative materials. Whether you are personalizing door fronts, drawer panels, or flat surfaces with a signature decorative motif, this round nose (core box) bit delivers clean, repeatable results with its right-hand rotation and integrated bearing guide. The bearing follower allows the bit to track along a template or straight edge, giving woodworkers and cabinet makers accurate, guided cuts for decorative groove routing and surface embellishment work.

Key Features

• 1/4" Radius Cutting Profile - produces a precise 1/4" semi-circular cove in a single pass, ideal for fluting columns, veining panels, and routing decorative grooves in solid wood and composite materials.
• Carbide-Tipped (HW) Flutes - hard carbide tips retain a sharp cutting edge longer than high-speed steel, reducing the frequency of bit replacement and maintaining clean cuts through hardwood, softwood, plywood, MDF, and other wood derivatives.
• 2-Flute Design - dual cutting edges produce a balanced, smooth cut with reduced vibration, resulting in cleaner surface finishes and less tear-out on delicate decorative work.
• Integrated Bearing Guide - the mounted bearing allows the bit to ride along a template edge or workpiece profile, enabling consistent, guided routing without the need for a fence, which is especially valuable for freehand decorative and curved-edge routing.
• 1/4" Shank - fits standard 1/4" collet routers, making this bit compatible with a wide range of handheld routers and router tables commonly used in woodworking and cabinetry shops.
• Right-Hand Rotation - matches the standard cutting direction of most router collets, ensuring safe, predictable operation when used in handheld routers, router tables, or CNC routing machines.
• 2" Total Length - compact overall length provides clearance for most router bases while maintaining rigidity for accurate decorative groove routing without flex or chatter.
• 3/8" Cutting Height - adequate cutting depth for surface-level decorative coves, veins, and flutes in panel work and door fronts without requiring multiple depth-setting passes.

Why This Product

• The integrated bearing guide makes this bit the right choice for template-guided decorative routing - it removes the guesswork of freehand routing and helps you replicate the same cove or groove profile across multiple workpieces consistently.
• The carbide-tipped (HW) cutting edges handle a broad range of materials - from solid hardwood and softwood to MDF, plywood, and other wood derivatives - so you do not need a separate bit for each material type.
• The 1/4" shank makes this bit accessible for use with compact and mid-size routers that accept 1/4" collets, giving hobbyist woodworkers and professionals alike a practical decorative routing solution without requiring a heavy-duty machine.
• The 2-flute configuration and right-hand rotation combine to deliver smooth, balanced cuts on decorative surfaces like door fronts and drawer panels where finish quality and surface clarity matter most.
