The CMT 83803 Contractor Roundover and Beading Bit is a 2-flute carbide-tipped router bit designed to transform sharp edges into smooth, refined roundover profiles with a 3/16 in. radius. Fitted with a 1/4 in. shank and a 7/8 in. cutting diameter, this bit works seamlessly in handheld routers and router tables alike. The beading profile option lets woodworkers go beyond basic edge softening - when paired with a cove bit, it opens the door to drop-leaf tables and other furniture joinery. Whether you are easing the edge of a cabinet door, rounding shelf corners, or shaping decorative furniture edges, this bit delivers consistent, repeatable results in both solid wood and sheet goods.

Key Features

• Roundover and Beading Profile (3/16 in. radius) - a versatile, widely used profile that softens sharp corners and also enables classic bead detailing, giving you two popular results from a single bit
• 2 Carbide-Tipped Cutting Edges - dual flutes produce cleaner cuts with less tear-out compared to single-flute designs, improving surface quality and reducing sanding time
• Anti-Kickback Design - limits the depth of cut per pass, reducing the risk of sudden grabbing or kickback so you stay in control throughout each routing pass
• Bottom Bearing Included - the ball-bearing pilot rides along the workpiece edge to maintain a consistent depth of cut without the need for fence setup on straightforward profiling tasks
• Heat-Treated Shank and Body - the hardened 1/4 in. shank resists bending and fatigue under repeated use, extending the working life of the bit in demanding contractor applications
• HW (Tungsten Carbide) Cutting Material - hard-wearing carbide tips hold a sharp edge longer than high-speed steel, making this bit suitable for hardwoods, softwoods, plywood, and other engineered wood products
• Right-Hand Rotation - compatible with the standard rotation direction of all conventional handheld routers and router tables, requiring no special setup or adapters

Why This Product

• The combined roundover and beading profile makes this a two-in-one edge treatment tool - run it with the bearing engaged for a clean roundover, or use it in conjunction with a cove bit to create drop-leaf table joints and decorative furniture profiles, all from a single bit purchase
• The anti-kickback body geometry and carbide-tipped dual cutting edges make this a reliable choice for contractors and woodworkers who need consistent edge quality across repeated production passes without sacrificing safety
• The 1/4 in. shank size fits virtually every handheld router and compact router table collet on the market, so this bit slots into an existing tool setup without requiring a dedicated machine or adapter
• The heat-treated body and hardened shank are built for durability in contractor-grade use, reducing the frequency of bit replacements and keeping production moving on furniture, cabinetry, and millwork projects
