The CMT 881.501.11 Solid Surface No-Drip Router Bit is a precision-engineered carbide routing bit designed to create clean, functional no-drip edges on kitchen and vanity countertops made from solid surface material. With a 1 in. cutting diameter, a 5/16 in. radius, and a 1/2 in. shank, this two-flute right-hand rotation bit profiles both the outer and inner edge in a single pass - producing a slightly raised lip that controls spilled liquids and prevents drips from running off the countertop edge. CMT engineered this bit specifically for handheld portable router use in applications where a guide bearing cannot be used, making it the practical choice for on-site countertop fabrication and edge profiling work.

Key Features

• Dual-profile no-drip geometry - cuts both the outer and inner profiles in one pass, creating a slightly raised edge that directs spilled liquids back toward the sink and prevents countertop drip-off without requiring tool changes or repositioning.
• Optimized for handheld portable routers - designed specifically for freehand routing applications where a guide bearing cannot be used, giving fabricators the flexibility to work directly on installed or semi-finished countertop surfaces.
• Hardmetal (HW) carbide cutting edges - industrial-grade carbide construction delivers durable, consistent cutting performance through solid surface material, extending bit life through repeated professional use.
• 2-flute right-hand rotation design - balanced two-tooth configuration promotes smooth chip evacuation and reduces heat buildup during solid surface edge profiling, helping maintain a clean, finished cut quality.
• 1/2 in. shank diameter - fits standard 1/2 in. collet routers for a secure, vibration-resistant connection that improves cut accuracy and reduces chatter on edge-profiling passes.
• 2 1/2 in. total length - provides adequate clearance for countertop edge work while keeping the bit stable and well-supported in the router collet during handheld operation.

Why This Product

• Countertop fabricators who need a single bit that handles both the outer and inner no-drip profiles will appreciate this bit's dual-profile geometry - it eliminates the need to swap bits mid-operation, saving setup time on kitchen and vanity installations.
• Because this bit is purpose-built for use without a guide bearing, it is the correct tool choice for routing no-drip edges on countertop applications where bearing-guided setups are impractical or impossible due to surface layout or installation constraints.
• The 5/16 in. radius and 1/2 in. cutting height are precisely sized for standard solid surface countertop edge thicknesses, ensuring the no-drip profile fits the material correctly without requiring manual adjustment or custom grinding.
• With a 1/2 in. shank and hardmetal carbide construction, this bit pairs with full-size handheld routers used in professional countertop shops, delivering repeatable edge quality across multiple countertop runs on the same job site.
