Product Description
CMT Solid Surface Rounding Over Router Bit - 1 1/8" Diameter x 19/32" Cutting Height, 5/16" Radius, 1/2" Shank by CMT is engineered specifically for creating smooth, traditional roundover profiles on solid surface countertops and worksurfaces. Whether you are profiling edges on Corian, Wilsonart, Gibraltar, or similar solid surface materials, this 2-tooth carbide-tipped bit delivers clean, consistent results with a protective Delrin bearing that guards finished edges from damage during the routing pass.
Key Features
- Solid surface rounding over bit designed for traditional roundover edge profiles - produces a smooth, uniform 5/16" radius curve ideal for countertop finishing work
- Non-marring Delrin bearing guides against the workpiece edge - protects finished solid surface material from scuffing or marring during profiling
- HW (carbide) cutting material with 2 cutting teeth - delivers clean, accurate cuts in solid surface materials while maintaining edge quality over extended use
- 1/2" shank for secure tool holding - provides rigid connection to the router collet, reducing vibration and improving cut accuracy
- Right-hand (RH) rotation - compatible with standard handheld portable routers for straightforward setup and operation
- 1 1/8" cutting diameter with 19/32" cutting height - sized to handle solid surface countertop edge profiles in a single pass without step marks
Why This Product
- Purpose-built for solid surface materials like Corian and similar products - unlike general-purpose roundover bits, this bit is optimized for the unique cutting characteristics of solid surface countertop material
- The Delrin non-marring bearing prevents surface damage during edge profiling - critical when working on finished countertop installations where scratching the surface would require costly rework
- A 5/16" radius roundover is one of the most widely specified edge profiles for solid surface countertops - making this bit a practical everyday choice for fabricators and installers
- Designed for use with handheld portable routers - giving fabricators the flexibility to profile edges on-site or in a shop setting without requiring a dedicated router table setup

Frequently Asked Questions
What size roundover radius does this bit produce?
This bit produces a 5/16" radius roundover profile, creating a smooth, traditional curved edge on solid surface countertops and worksurfaces.
What type of router is this bit compatible with?
This rounding over bit is designed for use with handheld portable routers. It features a 1/2" shank for a secure, stable connection to the router collet during profiling cuts.
Why does this bit use a Delrin bearing instead of a standard steel bearing?
The Delrin bearing is non-marring, meaning it will not scratch or damage the finished surface of solid surface countertop material as it guides along the workpiece edge. This is especially important when profiling completed or installed surfaces where surface damage would be difficult to repair.
What is the cutting height and overall length of this bit?
The cutting height is 19/32" and the total overall length of the bit is 2 29/64", giving you the geometry needed to complete a full roundover profile on solid surface countertop edges in a single routing pass.
