CMT Beading Bit with Bearing - 7/8" Diameter, 1/2" Cutting Height, 3/16" Radius, 1/4" Shank is a precision-ground carbide router bit from CMT designed to cut a classic bead profile along wood edges. Similar in shape to a roundover bit, the beading profile introduces a smaller bearing that creates a delicate inset at the base of the cut - giving furniture makers, cabinet builders, and trim carpenters an extra decorative flourish without a second setup. Whether you're running it in a handheld router or a router table, this 2-tooth right-hand rotation bit delivers clean, repeatable profiles in solid wood, sheet goods, and wood composites.

Key Features

• Beading profile with ball-bearing guide - the smaller bearing relative to the cutting radius produces a refined inset at the base of the bead, giving you an additional decorative detail not available with a standard roundover bit.
• 3/16" radius - a delicate, fine-scale profile ideal for detail work on furniture edges, cabinet face frames, and decorative trim where a subtle, elegant bead is desired.
• 7/8" cutting diameter with 1/2" cutting height - sized to handle typical edge-profiling tasks on solid lumber and panel products with a single pass at the router table or with a handheld router.
• 1/4" shank - compatible with compact and full-size routers fitted with a 1/4" collet, broadening the range of machines this bit can be used with.
• 2-flute hardmetal (HW) carbide construction - two cutting edges in a durable carbide formulation balance cutting speed with surface finish quality, reducing sanding time after profiling.
• Right-hand rotation (RH) - standard rotation direction matches the vast majority of handheld routers and router table setups, so no special tooling or adapter is required.
• 2 1/16" total length - a compact overall length that fits comfortably in most router collets and keeps the bit well-supported for stable, chatter-free cuts.

Why This Product

• The bead profile cut by this bit goes beyond a basic roundover - the inset detail at the base of the cut adds a classic furniture-grade look to cabinet doors, face frames, and table edges without requiring multiple bits or passes.
• The 1/4" shank makes this bit accessible to compact trim routers and laminate trimmers as well as standard routers, so woodworkers with smaller machines are not left out of decorative edge work.
• A carbide hardmetal (HW) construction means the cutting edges hold up through extended use in hardwood and softwood alike, reducing the frequency of bit changes during production runs.
• With a 3/16" radius and 1/2" cutting height, this bit is purpose-sized for fine detail work - a practical choice when the design calls for restraint rather than a heavy, oversized profile.
