CMT Contractor Cove Bit - 1 1/4" Diameter x 9/16" Cutting Height, 3/8" Radius, 1/4" Shank is a professional-grade carbide-tipped router bit from CMT, engineered to cut smooth, concave cove profiles along wood edges. Whether you are shaping cabinet door frames, adding decorative detail to drawer fronts, or creating furniture edge profiles, this cove router bit delivers clean, repeatable results with minimal tearout. Pair it with a roundover bit to build more complex decorative elements that elevate the appearance of any woodworking project.

Key Features

• Two carbide-tipped cutting edges - Hardwood-grade (HW) carbide tips provide a sharp, durable cutting surface that stays crisp longer through solid hardwood, softwood, and composite materials, reducing the need for frequent resharpening.
• Anti-kickback design - Limits the depth of each individual cut, reducing the risk of aggressive material grab and improving overall routing safety and accuracy, particularly in handheld router use.
• Bottom bearing included - A pilot bearing rides along the workpiece edge to maintain a consistent cove depth on every pass, eliminating the need for a fence when routing freehand profiles.
• Heat-treated shank and body - Thermal treatment increases the hardness and resilience of the 1/4" shank and body, helping the bit withstand the stresses of repeated routing sessions without premature wear or deflection.
• Right-hand rotation - Standard RH rotation is compatible with the vast majority of handheld routers and router tables, making this bit a straightforward drop-in choice for most workshops.
• 1/4" shank diameter - Fits a wide range of trim routers and standard routers equipped with a 1/4" collet, giving this compact cove bit broad machine compatibility.
• 3/8" radius cove profile - Produces a classically proportioned concave curve that works well for furniture edges, cabinet doors, and decorative molding details without being too bold or too subtle.

Why This Product

• Versatile decorative edge shaping - The 3/8" radius cove profile is a practical mid-size choice that suits cabinet door edges, drawer fronts, tabletop aprons, and furniture rails, making this a single bit that covers a wide range of common woodworking profiles.
• Safer routing through anti-kickback geometry - The anti-kickback body design controls the bite per pass, which is especially valuable when routing hardwoods or making unsupported freehand cuts, reducing the chance of the bit grabbing and the workpiece shifting.
• Consistent results with the included bearing - The bottom pilot bearing means you can produce identical cove profiles across multiple workpieces without resetting a fence, saving setup time and improving repeatability on production runs.
• Works with compact trim routers and full-size routers alike - The 1/4" shank makes this bit accessible to users with trim routers as well as standard routers with a 1/4" collet, so it fits naturally into workshops of any size without requiring a dedicated machine.
