CMT Pattern Bit - 3/4 in. Dia., 1 in. Cutter - 1/2 in. Shank

CMT Pattern Bit – 3/4 in. Diameter – 1/2 in. Shank

Versatile Template Routing for Precise, Repeatable Cuts

Whether you're a professional woodworker or a weekend woodworking enthusiast, the CMT Pattern Bit is a versatile addition to your router bit collection. Designed for template routing, this double-fluted bit opens up virtually unlimited possibilities for creating accurately shaped cabinets, furniture components, signs, toys, decorative pieces, and other custom woodworking projects.

The 3/4 in. diameter cutter features a 1/2 in. shank for secure installation in compatible routers and is equipped with a top-mounted bearing that follows the template while providing a clear view of the cutting area. This design helps you maintain control and achieve consistent, accurate results throughout the routing process.

Key Features

• 3/4 in. Diameter: Provides a versatile cutting profile for a wide range of template-routing applications.
• 1/2 in. Shank: Designed for use with compatible routers equipped to accept a 1/2 in. shank.
• Top Bearing: Follows the template accurately while helping provide clear visibility of the cutting area.
• Double-Fluted Design: Promotes efficient chip removal and smooth, controlled routing.
• Carbide Tipped: Built for long-lasting cutting performance and durability.
• Template Routing: Ideal for duplicating shapes and producing consistent profiles for cabinets, furniture, signs, toys, and custom projects.

Ideal Applications

The CMT Pattern Bit is designed for projects where a template is used to guide the router and reproduce a specific shape. It is particularly useful for making duplicate components, shaping curved or irregular workpieces, trimming material to a template, and creating repeatable designs.

• Cabinetmaking
• Furniture construction
• Template routing
• Sign making
• Toy making
• Decorative woodworking
• Custom and one-of-a-kind projects

Designed for Accuracy and Control

The top bearing allows the bit to track the edge of a securely mounted template while keeping the cutting area visible during operation. This combination of template guidance and carbide cutting edges helps woodworkers achieve clean, consistent results when reproducing shapes or trimming workpieces to a desired pattern.

Safety Tips

Always make sure your router is in proper working condition before use. Securely fasten the template to the workpiece to prevent movement during routing. When selecting a router bit, carefully consider the thickness of the template, the required cutting depth, and the overall requirements of the project. Whenever possible, choose the shortest bit that will safely accomplish the intended cut.

Safety Precautions

• Never use router bits that are damaged, cracked, excessively worn, or otherwise compromised.
• Operate the router at the manufacturer's recommended speed and use the proper feed rate for the material and application.
• Do not force the bit through the workpiece. Allow the cutting edges to remove material at a controlled rate.
• Exercise extra care when making the initial cut, particularly when using a small-diameter router bit.
• For best results with small-diameter bits, make deeper cuts in multiple passes rather than attempting to remove excessive material in one pass.
• Always wear appropriate eye and hearing protection and follow the safety instructions provided with your router.

How CMT Produces High-Quality Router Bits

CMT combines advanced manufacturing technology with carefully selected materials and precision machining processes to produce router bits designed for demanding woodworking applications.

• Turning, Milling and Cutting: CMT has invested heavily in modernizing its production facilities. Automated CNC machinery operated by specially trained personnel helps ensure that router bit bodies and shanks are manufactured to precise dimensions and properly balanced.
• Heat-Forged Steel Bodies for Large-Diameter Bits: Certain larger router bits undergo additional manufacturing processes, including heat forging before precision machining. This process creates a favorable radial grain orientation in the steel, helping provide increased strength and durability for larger-diameter tooling.
• Precision Brazing: CMT uses specially designed computerized brazing equipment to help maintain consistency during carbide attachment. Its silver-copper-silver brazing construction creates a strong bond between the steel body and carbide while helping absorb shock encountered during cutting.
• Specially Formulated Carbide: Different woodworking materials place different demands on cutting tools. CMT formulates carbide grades for specific applications, balancing hardness, durability, and impact resistance to suit various cutting requirements.
• Precision Grinding and Sharpening: The final grinding and sharpening processes are performed to tight tolerances to produce accurately shaped cutting edges and consistent tool performance.

A Dependable Choice for Template Routing

From professional cabinet shops to home woodworking benches, the CMT 3/4 in. Pattern Bit with 1/2 in. Shank provides a practical solution for template-guided routing. Its carbide-tipped construction, double-fluted design, and top bearing make it well suited for accurately reproducing shapes and creating repeatable results across a wide variety of woodworking projects.
