Product Description
CMT Contractor Cove Bit - 1" Diameter, 1/4" Radius, 1/4" Shank is a professional-grade router bit from CMT designed to cut smooth, concave cove profiles along wood edges and surfaces. With a 1/4" radius and a 2-flute carbide-tipped construction, this bit delivers clean, consistent results on solid hardwood, softwood, sheet goods, and more. Whether you are adding elegant detailing to cabinet doors and drawer fronts or creating decorative edge profiles on furniture, this cove bit pairs beautifully with a roundover bit to produce refined, custom design elements.
Key Features
- Two carbide-tipped cutting edges - dual flutes provide smoother cuts and a cleaner surface finish compared to single-flute designs, reducing sanding time.
- Anti-kickback design - controls the depth of cut on each pass, minimizing kickback risk and improving both safety and cut accuracy during edge routing.
- Heat-treated shank and body - enhanced hardness extends the service life of the bit and helps it resist bending or deflection under load.
- Bottom bearing included - the pilot bearing guides the bit along the workpiece edge for consistent cove depth and repeatable results without the need for a fence setup.
- 1/4" shank diameter - compatible with a wide range of compact routers, handheld routers, and router tables that accept a 1/4" collet.
- Right-hand rotation - standard RH rotation matches the cutting direction of all conventional routers, requiring no special setup.
- HW (carbide) cutting material - hard carbide tips stay sharper longer than high-speed steel alternatives, especially when working with abrasive materials like MDF or melamine.
Why This Product
- The 1/4" radius cove profile is a versatile decorative size - large enough to create a visually distinctive edge detail on doors and drawer fronts while remaining proportionate for smaller furniture components.
- The included bottom bearing eliminates the need for a separate guide fence for edge profiling work, making setup faster and freehand routing more controlled.
- The anti-kickback body geometry adds a meaningful layer of safety when routing solid hardwood or dense composite panels, where aggressive cuts can cause sudden bit grab.
- The 1/4" shank makes this bit accessible to woodworkers using compact trim routers or laminate trimmers as well as full-size router tables - no collet adapter needed for standard 1/4" setups.

Frequently Asked Questions
What profile does this bit cut?
This bit cuts a concave cove profile with a 1/4" radius. The resulting curved edge detail is commonly used on cabinet doors, drawer fronts, and furniture edges to add a classic, decorative appearance.
Can this cove bit be used with a handheld router and a router table?
Yes. The 1/4" shank is compatible with handheld routers, trim routers, and router tables that accept a 1/4" collet. The included bottom bearing guides the cut when routing freehand along an edge, while a router table fence can also be used for controlled passes.
What materials can this bit cut?
The carbide-tipped (HW) cutting edges are suitable for solid hardwood, softwood, plywood, MDF, chipboard, melamine, and similar wood-based panel products. Carbide stays sharper longer than high-speed steel, particularly in abrasive sheet materials like MDF and melamine.
What does pairing this cove bit with a roundover bit accomplish?
As noted in the product description, combining a cove bit with a roundover bit allows you to create custom decorative profiles and design elements on furniture and cabinet projects. The two profiles complement each other to produce more complex edge detailing than either bit achieves alone.
