Product Description
CMT Solid Surface Rounding Over Router Bit by CMT is a precision-engineered roundover profiling bit designed specifically for solid surface countertop edge work. Whether you are finishing Corian, Wilsonart, Gibraltar, or similar solid surface materials, this 3/4" diameter bit with a 1/8" radius delivers a smooth, traditional roundover edge profile with consistent results. Equipped with a non-marring Delrin bearing, it protects finished edges from scuffing during the routing pass, making it a dependable choice for professional countertop fabricators and skilled woodworkers alike.
Key Features
- Solid Surface Specific Design - engineered for use on solid surface countertop materials, ensuring clean, professional roundover edge profiles without tearing or chipping.
- Non-Marring Delrin Bearing - the Delrin bearing rolls smoothly against finished edges without scratching or leaving marks, preserving the surface quality of completed countertop work.
- 1/8" Roundover Radius - produces a refined, traditional roundover profile that softens countertop edges cleanly and consistently on every pass.
- Hard Metal (HW) Carbide Cutting Material - delivers long-lasting sharpness through demanding solid surface routing applications, reducing the need for frequent replacement.
- 2-Flute Configuration - dual cutting edges promote a balanced cut and smooth surface finish, improving edge quality and reducing vibration during operation.
- 1/2" Shank Diameter - the heavy-duty 1/2" shank provides a secure, stable grip in the router collet, minimizing deflection and improving cutting accuracy.
- Right-Hand Rotation - standard RH rotation is compatible with virtually all portable handheld routers, making this bit easy to put to work without special tooling.
- For Use with Hand-Held Portable Routers - optimized for handheld router operation, giving countertop fabricators flexible, on-site edge profiling capability.
Why This Product
- Designed specifically for solid surface countertop materials, this rounding over bit delivers the precise edge geometry needed for professional-grade countertop finishing - avoiding the inconsistencies that can result from using general-purpose bits on these specialty substrates.
- The non-marring Delrin bearing sets this bit apart for finish work: it guides along completed surfaces without leaving marks or scratches, protecting the quality of countertop edges during the profiling process.
- With a 1/2" shank and a total length of 2 11/32", this bit is built for stability and reach in handheld router applications, giving fabricators confident control through the full depth of cut.
- The hard metal carbide construction means the cutting edges hold up through extended use on solid surface materials, supporting productive, high-quality countertop edge profiling over many job runs.

Frequently Asked Questions
What type of router is this bit compatible with?
This bit is designed for use with hand-held portable routers equipped with a 1/2" collet. Its right-hand rotation is standard for the vast majority of handheld router models.
What is the radius this bit produces?
This rounding over bit produces a 1/8" radius roundover edge profile, creating a smooth, traditionally shaped edge on solid surface countertop material.
Why does this bit use a Delrin bearing instead of a standard steel bearing?
The Delrin bearing is non-marring, meaning it rolls along finished edges without scratching or marking the surface. This is especially important on solid surface countertop materials where surface quality must be preserved throughout the edge profiling process.
What solid surface materials is this bit suitable for?
This bit is designed for use with solid surface countertop materials such as Corian, Wilsonart, and Gibraltar, as well as comparable solid surface substrates used in countertop fabrication.
