CMT Cavetto Edge Mould Bit - 1-1/4" Diameter x 9/16" Cutting Height, 5/16" Radius, 1/2" Shank by CMT is a professional-grade router bit engineered to cut the classic cavetto profile - a traditional concave quarter-round moulding shape used in furniture, cabinetry, and decorative woodworking. With a 5/16" radius and 1 1/4" cutting diameter, this right-hand rotation bit delivers smooth, repeatable cove profiles in solid hardwood, softwood, plywood, MDF, and a wide range of composite sheet goods. Whether you are routing a full cavetto moulding or using only a portion of the cutting edge for a subtle, clean cove detail, this bit offers the flexibility to produce both bold traditional profiles and refined contemporary edge treatments.

Key Features

• Cavetto Profile Cutting Geometry - cuts a traditional concave quarter-round moulding shape and also allows partial use of the bit to produce a simpler, cleaner cove edge, giving you two distinct profile options from a single bit.
• 1 1/4" Cutting Diameter x 9/16" Cutting Height - delivers a substantial profile depth suitable for prominent decorative moulding on furniture edges, cabinet frames, and trim work.
• 5/16" Radius - produces a proportionally balanced concave curve that fits both traditional and transitional design aesthetics.
• 1/2" Shank - the larger shank diameter reduces vibration and deflection during the cut, resulting in smoother surface quality and greater accuracy compared to smaller shank sizes.
• HW (Hardwood-Grade) Carbide - 2 Teeth - industrial-quality carbide cutting edges stay sharp longer through dense hardwoods and composite materials, reducing the need for frequent resharpening or replacement.
• Right-Hand Rotation - standard RH rotation is compatible with the vast majority of handheld routers and router table setups, ensuring straightforward setup and safe operation.
• 2-13/32" Total Length - overall bit length provides adequate clearance for router table use and handheld router applications without excessive overhang.

Why This Product

• The cavetto bit's ability to cut either the full traditional concave moulding profile or just a portion of the edge profile means a single tool covers multiple design needs - from bold classical cove moulding to subtle decorative edge details on panels and frames.
• The 1/2" shank keeps the bit stable in both handheld router and router table setups, reducing chatter and producing cleaner results in hardwood and MDF without the surface tearout common with lighter-duty bits.
• With a 5/16" radius and 9/16" cutting height, this bit is sized for furniture and cabinetry applications where a visible, well-defined profile is required - not just a token edge break.
• The 2-flute HW carbide construction balances cut quality with durability, making this bit a practical long-term choice for woodworkers and shop professionals who route cove profiles regularly across a range of solid wood and sheet-good materials.
