CMT Solid Surface Rounding Over Router Bit - 1 1/2 in. Diameter, 3/4 in. Cutting Height, 1/2 in. Radius, 1/2 in. Shank by CMT is purpose-built for creating smooth, traditional roundover edges on solid surface countertop materials such as Corian, Wilsonart, and Gibraltar. This carbide-tipped profiling bit pairs a 1/2 in. radius profile with a non-marring Delrin bearing that protects finished edges during guided cuts, making it a reliable choice for countertop fabricators and woodworkers who demand clean, consistent results on solid surface work.

Key Features

• Solid surface rounding over profile - produces a classic, smooth 1/2 in. radius roundover edge on countertops and panels, delivering a finished, professional look without secondary sanding passes.
• Non-marring Delrin bearing - the bearing glides along finished surfaces without scratching or leaving marks, protecting your workpiece edges during profiling cuts.
• HW (carbide) cutting material - hard carbide construction maintains a sharp cutting edge longer than standard steel, reducing the frequency of bit replacement on demanding solid surface materials.
• 2-flute design - two cutting teeth provide balanced chip evacuation and a smoother cut finish on solid surface material, reducing tear-out and the need for touch-up work.
• Right-hand (RH) rotation - standard right-hand rotation is compatible with virtually all handheld portable routers, making setup straightforward without specialized tooling.
• 1/2 in. shank - the full 1/2 in. shank provides maximum grip and stability in the router collet, minimizing vibration and promoting straight, accurate edge profiles.
• Designed for handheld portable routers - optimized for field and shop use with handheld tools, giving countertop installers the flexibility to profile edges in place or at a workbench.

Why This Product

• Built specifically for solid surface countertop edge profiling - unlike general-purpose roundover bits, this bit is engineered for Corian and comparable materials, meaning it handles the unique characteristics of solid surface stock rather than being adapted from a wood-only design.
• The Delrin bearing eliminates surface damage risk - when profiling a finished countertop edge, a standard steel bearing can leave marks; the non-marring Delrin bearing removes that concern entirely, protecting your work from start to finish.
• A 1/2 in. shank on a bit this size reduces vibration and chatter - the combination of a 1 1/2 in. cutting diameter and a full 1/2 in. shank provides the rigidity needed for smooth, consistent passes on wider edge profiles.
• Compact 2 19/32 in. total length keeps the bit manageable in handheld router applications - shorter overall length improves balance and control during freehand countertop edge work, where maneuverability matters.
