CMT Cove Bit with Bearing - 1 1/8" Diameter, 1/2" Cutting Height, 5/16" Radius, 1/4" Shank is a precision router bit from CMT designed to cut smooth, concave cove profiles along wood edges. Whether you are shaping furniture components, adding decorative detail to cabinet doors, or finishing drawer fronts with a refined curved edge, this cove bit delivers consistent results on solid hardwood, softwood, and sheet goods alike. The integrated ball-bearing guide rides along the workpiece to maintain a uniform depth of cut on every pass, making it equally at home in a handheld router or mounted in a router table.

Key Features

• 5/16" Cove Radius - produces a smooth, elegant concave curve that adds a refined, professional finish to furniture edges, door frames, and drawer fronts without the need for sanding to shape.
• Ball-Bearing Guide - follows the workpiece edge automatically to maintain a consistent cutting depth on every pass, reducing the chance of uneven profiles or material tearout.
• 1/4" Shank - fits a wide range of standard routers and collets, making this bit a versatile addition to any woodworking setup.
• 2-Flute (2-Tooth) Design - dual carbide cutting edges produce a balanced, chatter-free cut and a cleaner surface finish compared to single-flute alternatives.
• HW (Hard Metal / Carbide-Tipped) Cutting Material - industrial-grade carbide cutting edges stay sharp longer when routing hardwoods, softwoods, plywood, and MDF, reducing the frequency of bit changes.
• Right-Hand Rotation - standard RH rotation is compatible with virtually all handheld routers and router tables, so no special setup is required.
• 1 1/8" Cutting Diameter with 1/2" Cutting Height - provides a generous cutting envelope for decorative edge work in a single pass on most common stock thicknesses.
• 2 1/8" Total Length - compact overall length keeps the bit stable and reduces vibration during use, contributing to cleaner cuts and longer bearing and bit life.

Why This Product

• The integrated bearing guide eliminates the guesswork of freehand routing - the bit self-registers against the workpiece edge for repeatable, consistent cove profiles across every piece in a production run or matched set of furniture components.
• With a 1/4" shank, this bit is compatible with a broad range of compact and full-size routers, making it accessible to hobbyists and professional woodworkers who do not want to dedicate a large-shank machine to detail work.
• The 5/16" radius cove profile is a versatile decorative detail suited for furniture edges, cabinet door styling, and drawer front accents - adding a polished, hand-crafted appearance to finished pieces.
• Hard metal (HW) carbide construction means the bit handles repeated passes through dense hardwoods and engineered sheet goods without rapid dulling, giving it practical longevity in shop use.
