The CMT 86304 Contractor Cove and Fillet Bit is a precision router bit designed to add elegance and visual depth to furniture edges, cabinetry, and decorative trim work. This bit combines a traditional cove cut with a fillet detail to create a distinctive, eye-catching profile that elevates the look of any woodworking project. With a 1 3/8" cutting diameter, a 21/32" cutting height, and a 3/8" radius, this cove and fillet bit delivers a classic moulding profile suited for handheld routers and router tables alike. Featuring 2 carbide-tipped cutting edges and an anti-kickback body design, the CMT 86304 is built for consistent, controlled performance across a wide range of wood species and sheet materials.

Key Features

• Cove and Fillet Profile - combines a concave cove cut with a fillet detail in a single pass, adding decorative elegance to furniture edges, cabinet faces, and moulding work without the need for multiple bits.
• 2 Carbide-Tipped Cutting Edges (HW Material) - hard-metal carbide tips stay sharp longer through demanding cuts in hardwood, softwood, and sheet goods, reducing the need for frequent bit changes or replacements.
• Anti-Kickback Design - controls the depth of cut at any given moment, minimizing the risk of sudden kickback and improving operator safety during freehand and table-mounted routing.
• Heat-Treated Shank and Body - the hardened shank and body resist deflection and stress during cutting, supporting accuracy and extending the usable life of the bit over repeated use.
• Bottom Bearing Included - the integrated bottom bearing guides the bit along the workpiece edge, ensuring a consistent profile depth without the need for a fence on straightforward edge work.
• 1/4" Shank - fits a wide range of handheld routers and router tables equipped with a 1/4" collet, making this bit a versatile addition to most woodworking setups.
• Right-Hand Rotation - compatible with standard right-hand router collets, so no special setup or adapter is required for typical router use.

Why This Product

• The combined cove-and-fillet profile is achieved in a single pass, saving setup time compared to using separate bits and delivering a clean, consistent decorative edge on furniture, cabinet doors, and custom mouldings.
• The anti-kickback body design makes this bit a practical choice for woodworkers who need reliable safety control, especially when routing hard or dense materials where sudden catches are a greater risk.
• The 1/4" shank makes this bit broadly compatible with compact and mid-size routers that are commonly used for furniture and cabinetry work, removing the need for a large router or a collet adapter.
• With carbide-tipped cutting edges and a heat-treated body, this contractor-grade cove and fillet bit is built to handle repeated use across solid hardwood, softwood, plywood, MDF, and similar materials - making it a durable, long-term tooling investment.
