CMT Contractor Cove and Fillet Bit by CMT combines a traditional cove profile with a refined fillet cut, producing an eye-catching decorative edge that adds elegance to furniture, cabinetry, and fine woodworking projects. With a 1/4 in. radius, a 1 1/8 in. cutting diameter, and a 9/16 in. cutting height, this router bit delivers clean, consistent concave profiles in a single pass. The 1/4 in. shank fits a wide range of handheld routers and router tables, making it a versatile choice for both shop and jobsite use.

Key Features

• Carbide-Tipped Cutting Edges (HW Material): two hardened carbide tips maintain a sharp cutting edge longer than standard high-speed steel, reducing the frequency of bit changes and delivering smooth, splinter-free profiles in hardwood, softwood, and sheet goods.
• Anti-Kickback Design: limits the depth of cut on each pass, minimizing the risk of dangerous bit grab and giving the operator more control - especially important when routing curved profiles freehand or on a router table.
• Right-Hand Rotation: designed for standard router operation so the bit feeds correctly against the workpiece, producing a clean cut without chatter or tear-out.
• Heat-Treated Shank and Body: resists the stress and heat generated during repeated routing passes, extending the working life of the bit and maintaining dimensional accuracy over time.
• Bottom Bearing Included: the integrated guide bearing rides along the workpiece edge to control the lateral position of the cut automatically, eliminating the need for a fence when routing straight or curved stock.
• 1/4 in. Shank: compatible with virtually every standard router collet, making this bit a practical addition to an existing router setup without requiring additional adapters.
• Combined Cove and Fillet Profile: the two-part cut - a concave quarter-round cove paired with a flat fillet - produces a classic furniture and architectural moulding profile in one router pass, saving time compared to using multiple bits.

Why This Product

• The cove-and-fillet profile is a classic furniture edge treatment that would otherwise require multiple setups or hand-tool work - this bit achieves the full decorative profile in a single router pass, saving significant time in production and custom work.
• The anti-kickback body geometry makes this bit suitable for woodworkers of varying experience levels, providing a safer cutting experience when routing decorative edges on chair rails, tabletops, cabinet doors, and furniture frames.
• Two carbide-tipped cutting edges mean the bit can handle repeated use across hardwood and softwood species as well as sheet materials like plywood and MDF without losing sharpness prematurely.
• The included bottom bearing eliminates the need for a router table fence when profiling curved or irregular workpiece edges, making this bit as practical for template routing as for straight-line work.
