The CMT 151.064.25D Solid Surface and Fiberglass Bit is a premium solid carbide routing and drilling tool engineered for precise, clean machining of fiberglass, phenolic panels, and solid surface materials. With its 135 deg. tooth geometry and positively ground cutting edge, this 1/4 in. bit delivers vertical feeding capability that minimizes workpiece bending - making it an excellent choice for CNC routers, machining centers, point-to-point machines, and handheld routers equipped with chucks or adaptors. Whether you are drilling, sizing, or jointing composite laminates and solid surface sheets, this right-hand rotation bit is purpose-built to handle the abrasive demands of these challenging materials while producing an excellent surface finish.

Key Features

• 135 deg. tooth geometry - allows for vertical feeding into the workpiece, minimizing bending and deflection during drilling and routing operations for cleaner, more accurate results.
• Premium HWM (hardmetal) solid carbide construction - provides the wear resistance needed to stand up to the highly abrasive nature of fiberglass, phenolic, and solid surface materials, extending tool life between resharpenings.
• Special positively ground cutting edge sharpening - produces an excellent finish on solid surfaces and composite panels, reducing secondary sanding or cleanup work after machining.
• 1/4 in. shank with 1 in. cutting height - compatible with standard router collets and chuck adaptors on CNC routers, machining centers, and handheld routers, giving broad machine compatibility without special toolholding requirements.
• Right-hand rotation - matches the standard spindle direction of the vast majority of CNC routers and handheld routing equipment, making setup straightforward.
• Designed for drilling, sizing, and jointing operations - a single tool handles multiple machining tasks on fiberglass and solid surface workpieces, reducing tool changes and setup time.

Why This Product

• The 135 deg. drill point geometry is specifically developed for vertical plunge feeding into fiberglass and composite panels - reducing the risk of workpiece delamination or bending that occurs with standard router bits not designed for these materials.
• The positively ground premium HWM carbide edge delivers a notably clean finish when machining solid surfaces such as Corian-type materials and phenolic laminates, where surface quality is critical for jointing and sizing applications.
• At 2 1/2 in. total length with a 1/4 in. shank, this bit fits seamlessly into machining centers, point-to-point CNC machines, and handheld routers with chuck adaptors - covering both production shop and job-site routing scenarios.
• The combination of drill point geometry and solid carbide material make this bit a purpose-matched tool for fiberglass routing, where generic bits tend to wear rapidly and produce frayed or rough cut edges.
