The CMT 880.531.11 Solid Surface No-Drip Router Bit is a precision-engineered profiling bit designed to create clean, raised no-drip edges on kitchen and vanity countertops in a single pass. Built for use with hand-held portable routers and featuring a 1/2" shank, this solid surface bit cuts both the outer and inner profiles simultaneously, producing a slightly raised edge that controls spilled liquids and prevents drips from running off the countertop surface. Crafted from hard metal (HW) carbide, the CMT 880.531.11 is an ideal choice for fabricators and installers working with solid surface countertop materials such as Corian, Wilsonart, Gibraltar, and similar products.

Key Features

• No-drip edge profile in a single pass - cuts both the outer and inner profiles simultaneously, saving time and reducing setup steps on countertop edge work.
• Slightly raised edge geometry - the resulting profile controls spilled liquids and keeps drips on the countertop surface rather than running off the edge, a practical solution for kitchen and vanity installations.
• Delrin non-marring bearing - the Delrin bearing protects finished solid surface edges from scratching or marring during the routing pass, preserving the quality of the finished countertop.
• Hard metal (HW) carbide construction - delivers durable cutting performance through dense solid surface materials, helping maintain a sharp edge over extended use.
• Right-hand rotation - matches the standard rotation direction of hand-held portable routers, ensuring safe and predictable operation.
• 1/2" shank diameter - provides a secure, stable fit in standard router collets, reducing vibration and improving cut quality during edge profiling.
• 2-flute design - two cutting teeth deliver smooth, consistent material removal and a clean finished profile on solid surface countertop edges.
• 5/16" radius - produces a precisely defined curved profile that is well-suited to the no-drip edge geometry used in professional countertop fabrication.

Why This Product

• One-pass countertop edge solution - because this bit cuts both the outer and inner profiles in a single pass, fabricators can complete no-drip edge work faster and with fewer tool changes compared to using multiple bits.
• Designed specifically for solid surface materials - this bit is purpose-built for countertop work in materials like Corian and similar solid surfaces, making it a focused tool rather than a general-purpose bit adapted for the task.
• Protects finished surfaces during routing - the Delrin non-marring bearing prevents scratches and marks on finished solid surface edges, which is critical when working on visible, polished countertop installations.
• Practical drip-control geometry - the slightly raised edge profile produced by this bit actively helps manage spilled liquids on kitchen and vanity countertops, adding functional value to the finished installation beyond aesthetics alone.
