CMT Round Nose Bit with Bearing - 3/4 in. Diameter, 3/8 in. Radius, 1/4 in. Shank by CMT is a precision carbide-tipped router bit engineered for cutting smooth, semi-circular coves and decorative grooves in wood and wood derivatives. Whether you are fluting cabinet doors, adding veining details to drawer fronts, or routing decorative accents across panels and flat surfaces, this round nose (core box) bit delivers clean, consistent results. The bearing guide keeps cuts precise and repeatable, making it equally at home in a handheld router, a router table, or a CNC routing setup.

Key Features

• 3/4 in. cutting diameter with 3/8 in. radius - produces a true semi-circular profile in a single pass, giving you a clean cove or flute without multiple setups or repositioning.
• Carbide-tipped (HW) flutes - hard carbide material stays sharper longer than high-speed steel, meaning fewer interruptions for bit changes and more consistent surface quality across long production runs or intricate decorative work.
• Bearing guide included - the integrated bearing rides along the workpiece edge or a template, controlling the cut path automatically so your grooves and coves stay perfectly aligned without additional fences or jigs.
• 2-flute (2-tooth) configuration - dual cutting edges balance feed rate and finish quality, producing a smoother surface inside coves and reducing tear-out in hardwood and wood composites.
• 1/4 in. shank - fits a wide range of compact and full-size routers with 1/4 in. collets, broadening compatibility so the bit works with tools you likely already own.
• 7/16 in. cutting height - provides sufficient depth capacity for most decorative cove and fluting profiles without requiring multiple shallow passes.
• Right-hand (RH) rotation - matches the standard rotation direction of virtually all consumer and professional routers, so installation is straightforward with no special setup required.
• 2 in. total length - a compact overall length keeps the bit stable and reduces vibration during cuts, contributing to cleaner edges and a longer tool life.

Why This Product

• The built-in bearing guide removes guesswork from decorative routing - it follows your workpiece or template automatically, so you get repeatable cove and flute profiles across every door, drawer front, or panel in a set without resetting a fence for each piece.
• The carbide-tipped construction handles solid hardwood, softwood, plywood, MDF, and other wood derivatives, making this a single bit capable of covering a wide range of decorative routing tasks rather than requiring separate tools for different materials.
• The 3/8 in. radius (3/4 in. diameter) profile is one of the most commonly specified sizes for cabinet fluting and decorative panel work, so this bit addresses a frequent need without the cost of custom tooling.
• With a 1/4 in. shank and standard right-hand rotation, this bit slots directly into the routers most woodworkers already have - there is no need for a specialized collet adapter or a dedicated machine to use it.
