The CMT 83802 Contractor Roundover and Beading Bit is a 2-flute carbide-tipped router bit designed to transform sharp corners into smooth, finished edges with a clean 1/8" radius profile. Built for use in handheld routers and router tables alike, this bit handles solid hardwood, softwood, plywood, MDF, and more - making it a practical go-to for furniture edge work, cabinetry, and decorative trim. Its anti-kickback body geometry keeps cuts controlled and consistent, while the included bottom bearing rides along the workpiece to guide depth automatically. When paired with a matching cove bit, the 83802 opens up more advanced joinery options like drop-leaf table edges and other multi-step profile work.

Key Features

• 2 Carbide-Tipped Cutting Edges - dual flutes deliver cleaner cuts per pass and extend the working life of the bit compared to single-edge designs, reducing sanding and finishing time.
• Anti-Kickback Design - limits the depth of each bite into the material, reducing the risk of sudden kickback and improving both safety and cut accuracy on the router table or freehand.
• Bottom Bearing Included - the ball-bearing pilot rides along the edge of the workpiece to maintain a consistent 1/8" radius profile without requiring manual depth adjustments mid-cut.
• Hardwood (HW) Carbide Material - industrial-grade carbide retains a sharp cutting edge through extended use across hardwood, softwood, plywood, MDF, and composite materials.
• Heat-Treated Shank and Body - thermal treatment adds structural strength to the 1/4" shank and bit body, reducing deflection and improving durability under repeated routing loads.
• Right-Hand Rotation - standard RH rotation is compatible with virtually all handheld routers and router table setups, eliminating compatibility concerns for most workshops.
• Roundover and Beading Capability - one bit handles both rounding over sharp edges and forming a decorative bead profile, giving woodworkers more versatility from a single tool.

Why This Product

• The 1/8" radius is a widely used profile for softening edges on furniture, cabinet doors, and trim - small enough to look refined without dramatically changing the piece's overall geometry.
• The anti-kickback body design is built directly into the bit's geometry, not added as an afterthought, so safer cutting behavior is maintained throughout the full life of the bit.
• With a 1/4" shank and 2 1/16" total length, this bit fits compact routers and standard router tables equally well, making it accessible whether you are working on a job site or in a dedicated shop setup.
• The dual function as both a roundover bit and a beading bit - plus its compatibility as a drop-leaf profile partner with a cove bit - means this single tool supports a wider range of project types than a standard roundover-only bit.
