CMT Lettering Bit - 1 1/8" Diameter x 3/4" Cutting Height, 60 deg. Angle, 1/2" Shank by CMT is a precision-engineered engraving and sign-making router bit designed for carving attractive lettering in wood without splitting or chipping. Whether you are routing V-groove text for decorative signs, carving relief letters, or beveling edges around the base of characters, this 60 deg. lettering bit delivers clean, accurate results on a wide range of wood and composite materials. Built with two tungsten carbide (HW) cutting teeth and right-hand rotation, it is compatible with handheld routers, router tables, and CNC routing machines.

Key Features

• 60 deg. engraving angle - produces precise V-groove letterforms and decorative cuts ideal for sign-making and letter carving in relief, giving crisp, professional-looking results.
• 1 1/8" cutting diameter - provides a wide enough sweep to form bold, readable characters and decorative grooves in a single controlled pass.
• 3/4" cutting height - gives sufficient depth capacity for routing through typical sign blanks and relief lettering stock without multiple plunge passes.
• Flattened bottom geometry - makes relief letter-making easy and accurate by allowing you to efficiently level the area around the base of each letter and bevel edges to eliminate splintering.
• 2-flute (2-tooth) tungsten carbide (HW) construction - delivers clean shear cuts in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic, reducing tear-out and extending cutting life.
• 1/2" shank diameter - provides a secure, low-vibration connection in standard 1/2" router collets, contributing to routing accuracy and surface quality.
• Right-hand rotation - matches the standard rotation direction of conventional routers and CNC spindles for straightforward setup and safe operation.
• 2 1/2" total length - allows adequate clearance above the workpiece when used in router tables or CNC setups, reducing interference with fixtures and fences.

Why This Product

• The 60 deg. included angle is specifically engineered for lettering and sign carving - not a general-purpose V-bit - meaning the geometry is optimized to produce clean character profiles without chipping the wood fibers at the base of each cut.
• The flattened bottom design solves a common sign-making challenge: leveling the field around relief letters is built into a single bit rather than requiring a separate operation, saving setup time and improving consistency.
• With a 1/2" shank and two carbide teeth, this bit is built for stability in production routing environments, including router tables and CNC routing machines where repeatability across multiple cuts matters.
• The bit is compatible with a wide range of materials - solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic - making it a versatile choice for both custom sign shops and woodworking workshops handling varied stock.
