The CMT 151.127.38D Solid Surface and Fiberglass Bit is a premium solid carbide router bit engineered for precision drilling, sizing, and jointing of fiberglass, phenolic, and solid surface materials. With a 1/2 in. cutting diameter, 1 1/2 in. cutting height, and 3 1/2 in. total length, this right-hand rotation bit delivers clean, accurate results on CNC machining centers, point-to-point machines, CNC routers, and handheld routers equipped with chucks or adaptors. Designed to handle the abrasive demands of composite routing and fiberglass cutting, it brings professional-grade performance to both production shops and specialty fabrication environments.

Key Features

• 135 deg. tooth geometry with drill point design - allows for vertical feeding directly into the workpiece, minimizing bending and deflection of thin or flexible panels for cleaner, more accurate cuts.
• Premium quality HWM (hard metal) carbide construction - the specially positively ground cutting edge sharpening delivers an excellent finish on fiberglass, phenolic, and solid surface materials, reducing the need for secondary cleanup.
• 1/2 in. shank diameter - compatible with a wide range of CNC machining centers, point-to-point machines, CNC routers, and handheld routers fitted with chucks or adaptors, providing versatile setup options across machine types.
• 1 1/2 in. cutting height paired with 3 1/2 in. total length - provides sufficient reach and cutting depth for sizing and jointing operations in solid surface and composite panel work.
• Right-hand (RH) rotation - matches the standard spindle direction of most CNC and handheld router platforms, ensuring straightforward installation without special toolholding adaptors.
• Optimized for abrasive composite materials - the cutting geometry and carbide grade are specifically suited to fiberglass and phenolic applications, extending tool life compared to general-purpose router bits used on the same materials.

Why This Product

• Fiberglass and phenolic materials are highly abrasive and can quickly degrade standard router bits - the premium HWM carbide grade and specially ground cutting edge of this bit are specifically formulated to handle that abrasiveness, making it a reliable choice for production routing of these materials.
• The 135 deg. drill point geometry enables direct vertical plunge entry into the workpiece, solving a common challenge when routing thin or unsupported composite panels where bending and tear-out are concerns.
• With a 1/2 in. shank and compatibility across CNC machining centers, point-to-point machines, CNC routers, and chuck-equipped handheld routers, this bit integrates easily into existing shop setups without requiring dedicated tooling systems.
• The positively ground cutting edge is engineered to produce an excellent finish on solid surface materials such as Corian-type substrates, reducing finishing time and improving overall part quality directly off the router.
