The CMT 83806 Contractor Roundover and Beading Bit is a 2-tooth, carbide-tipped router bit designed to transform sharp edges into smooth, refined 3/8" radius profiles on wood, sheet goods, and more. With a 1 1/4" cutting diameter and a 1/4" shank, this bit is a reliable choice for furniture edge work, cabinetry, and decorative trim profiling - offering the added versatility of creating a classic bead detail when the bearing is removed. Its anti-kickback body design and heat-treated shank make it a trusted tool for both handheld router use and router table applications.

Key Features

• 2 Carbide-Tipped Cutting Edges (HW Material) - Hard-wearing carbide tips maintain a sharp cutting edge through demanding production runs, reducing the need for frequent bit changes and delivering cleaner profiles in solid wood, plywood, MDF, and similar materials.
• Anti-Kickback Design - The body geometry controls the maximum depth of cut per pass, reducing the risk of sudden kickback and giving the operator greater control and accuracy at the router table or with a handheld router.
• Heat-Treated Shank and Body - Thermal treatment increases the hardness and durability of the 1/4" shank and bit body, helping the bit resist deflection and wear during extended use.
• Bottom Bearing Included - The included ball-bearing pilot rides along the workpiece edge to maintain a consistent cutting depth, producing a uniform 3/8" roundover profile pass after pass without the need for a fence setup.
• Roundover and Beading Capability - This bit produces a smooth rounded edge profile and, when used with the bearing removed or adjusted, creates a decorative bead - making it a versatile single-bit solution for multiple edge profiles.
• Right-Hand Rotation - Engineered for standard right-hand router rotation, ensuring compatibility with the vast majority of handheld routers and router tables commonly used in woodworking shops.
• 3/8" Radius Profile - A 3/8" radius is one of the most commonly specified roundover profiles in furniture and cabinetry, softening sharp corners to a comfortable, finished appearance without removing excessive material.

Why This Product

• The dual-function roundover and beading capability means one bit can handle two distinct edge profiles - a smooth 3/8" roundover for softening corners or a classic bead detail for decorative work - reducing the number of bits needed in a set.
• The anti-kickback body design makes this bit a safer choice for router table use, particularly when profiling narrow workpieces or making full-depth passes along long edges of panels or furniture components.
• With a 21/32" cutting height and 1 1/4" diameter, this bit covers enough edge depth to handle typical furniture parts, door edges, and tabletops in a single pass, improving efficiency on production-style work.
• When paired with a cove bit, this roundover and beading bit enables the creation of drop-leaf table joints and other interlocking edge profiles - expanding its usefulness well beyond basic edge softening.
