The CMT Ovolo Bit (827.660.11) is a professional-grade carbide-tipped router bit engineered to produce classic convex bead profiles, elegant roundovers, and decorative edge work on furniture, cabinetry, and millwork. With a 1 3/4 in. cutting diameter, a 5/8 in. radius, and a 1/2 in. shank, this versatile bit can be used on handheld routers, router tables, and automated CNC routing systems. By simply adjusting the height or depth of cut, woodworkers can generate a wide variety of single and double bead profiles from a single bit - making it an exceptionally efficient tool for furniture makers and production shops alike.

Key Features

• 1 3/4 in. Cutting Diameter with 5/8 in. Radius - a generous cutting envelope that allows you to produce bold, classically proportioned ovolo and bead profiles in a single pass without multiple tool changes.
• 2-Flute Carbide (HW) Construction - twin cutting edges in industrial hardmetal carbide deliver smooth, clean cuts while doubling the number of cuts per revolution, reducing tear-out on hardwood and softwood surfaces.
• 1/2 in. Shank - the larger shank diameter provides greater rigidity and stability compared to smaller shanks, reducing vibration and chatter for cleaner edge profiles and improved cut accuracy.
• Right-Hand Rotation - designed for standard router spindle direction, ensuring compatibility with the widest range of handheld routers, router tables, and CNC routing machines.
• 7/8 in. Cutting Height - provides sufficient depth capacity to fully form the ovolo profile in solid hardwood, softwood, plywood, and sheet goods in a controlled, consistent pass.
• Versatile Profile Adjustment - adjusting the height or depth of cut on a router table or with a fence produces a wide variety of single and double bead profiles and roundovers from one bit, replacing the need for several individual profile bits.
• 2 3/8 in. Total Length - a compact overall length keeps the bit well-balanced and manageable in both handheld and table-mounted setups, contributing to stable, repeatable results.

Why This Product

• One ovolo bit replaces several individual profile bits - by adjusting cut height or depth, furniture makers and cabinet shops can produce a wide variety of single and double bead profiles and roundovers without swapping tooling, saving time and reducing tooling cost.
• The 2-flute hardmetal carbide (HW) design is built for consistent performance across a broad range of materials including solid hardwoods, softwoods, plywood, and sheet goods, making this bit a practical choice for both production environments and custom shop work.
• With a 1/2 in. shank and right-hand rotation, this bit is compatible with a wide variety of routers and CNC routing systems, giving it flexibility across different shop setups and workflow configurations.
• The 5/8 in. radius and 7/8 in. cutting height produce full, classically proportioned ovolo profiles suited to traditional furniture edges, decorative beadwork, and fine millwork applications where profile quality matters.
