The CMT 866.601.11 Solid Surface Rounding Over Bowl Bit is a precision router bit engineered specifically for undermount sink and bowl applications on solid surface countertop materials. With a 2 deg. cutting diameter, a 1/2 in. radius profile, and a 15 deg. bevel angle, this bit delivers the shaped edge geometry needed to join countertops and sink bowls cleanly and accurately. Designed for use with handheld routers, it trims and shapes all wood and wood-based materials, making it a reliable choice for kitchen and bathroom countertop fabrication professionals.

Key Features

• 15 deg. Bevel Angle with 1/2 in. Radius Profile - produces the specific rounding-over geometry required for undermount bowl applications, ensuring a clean, finished edge where countertop meets sink bowl.
• 2 in. Cutting Diameter - provides a wide sweep for consistent contact across the edge profile, reducing the number of passes needed for a finished result.
• 1 in. Cutting Height - accommodates material thicknesses up to 3/4 in., covering standard solid surface countertop stock without repositioning.
• HW (Hardwood-Grade) Carbide Construction with 2 Cutting Teeth - delivers sharp, clean cuts on solid surface, wood, and wood composite materials while maintaining edge quality over extended use.
• Right-Hand (RH) Rotation - compatible with standard handheld routers, so there is no need for special tooling or reverse-rotation equipment.
• 1/2 in. Shank Diameter - fits standard 1/2 in. router collets for a secure, low-vibration grip that supports precise profiling on countertop edges.
• Maximum Material Thickness of 3/4 in. - aligns directly with common solid surface slab dimensions, making setup straightforward without additional spacers or jigs.

Why This Product

• Specifically engineered for undermount bowl joining - the 15 deg. bevel angle and 1/2 in. radius are designed for the exact edge geometry required when bonding solid surface countertops to undermount sink bowls, eliminating guesswork in profile selection.
• Handles solid surface, wood, and wood-based materials with a single bit - making it a versatile addition for countertop fabricators who work across multiple substrate types in kitchen and bathroom applications.
• The 1/2 in. shank and right-hand rotation mean this bit mounts directly to standard handheld routers with no adapters or special collets required, reducing setup time on the job.
• With 2 cutting teeth and hardwood-grade carbide, the bit sustains cutting performance through the demanding shapes required for countertop bowl integration, supporting production-level work without frequent tool changes.
