CMT 866.602.11 Solid Surface Rounding Over Bowl Bit by CMT is a precision router bit engineered specifically for undermount sink and bowl installations in solid surface countertop work. With a 2 in. cutting diameter, a 1/2 in. radius profile, and a 15 deg. beveled angle, this bit trims and shapes all wood and wood-based materials with accuracy - making it the go-to choice for kitchen and bathroom countertop fabrication. Designed for use on hand-held routers with a 1/2 in. shank, it delivers clean, consistent profiles where the countertop meets the sink bowl, eliminating the guesswork from undermount applications.

Key Features

• 15 deg. Beveled Angle Profile - creates the signature angled edge required for undermount bowl and sink installations, producing a professional, factory-quality junction between countertop and bowl without additional finishing steps.
• 2 in. Cutting Diameter with 1/2 in. Radius - provides a broad cutting sweep and smooth rounded profile in a single pass, reducing the time and effort needed to shape solid surface edges on countertops.
• 1 1/4 in. Cutting Height - accommodates countertop material up to 1 in. thick, giving fabricators the clearance needed to complete a full-depth profile cut in standard solid surface stock.
• HW (Hardwood/Hard Material) Carbide Construction - the carbide-grade tooling stands up to repeated cutting through dense solid surface materials, extending the useful life of the bit in high-production countertop environments.
• 2-Flute (2-Tooth) Design - dual cutting edges balance chip load and produce a smoother surface finish compared to single-flute alternatives, reducing sanding and cleanup time after routing.
• Right-Hand (RH) Rotation - compatible with the standard rotation direction of virtually all hand-held routers, ensuring safe, predictable cutting behavior without any modification to your equipment.
• 1/2 in. Shank - the large-diameter shank provides maximum rigidity in the collet, minimizing vibration and deflection during cuts to keep profiles consistent and clean throughout the entire cut path.

Why This Product

• Purpose-built for undermount bowl work - unlike general-purpose roundover bits, this bit is specifically designed for the undermount application where countertop and sink bowl surfaces must meet at a precise 15 deg. beveled edge, eliminating improvised setups or multi-bit workflows.
• Handles countertop stock up to 1 in. thick - with a maximum material thickness rating of 1 in. and a 1 1/4 in. cutting height, fabricators can work through full-thickness solid surface slabs in a single pass rather than making multiple shallow cuts.
• Compatible with solid surface countertop materials used in kitchens and bathrooms - this bit is suited to the wide range of solid surface substrates found in residential and commercial countertop fabrication, making it a versatile addition to any countertop shop's routing toolkit.
• Designed for hand-held router use - the 1/2 in. shank and right-hand rotation make this bit straightforward to mount and run on standard portable routers, keeping setup simple for on-site countertop fabrication or shop-based production work.
