CMT Mortising Bit, 1/2 in. Dia., 3/4 in. Cutting Height, No Bearing, 1/4 in. Shank

Create clean, precise mortises with a router bit engineered for smooth cuts and long-lasting performance.

The CMT Mortising Bit features thick carbide tips and a negative shear angle design to deliver exceptional cutting performance in both natural wood and wood composites. Designed for hinge mortising, template routing, and sign-making applications, this bit produces clean mortises with minimal splintering and smooth bottom surfaces.

Compatible with most popular mortising jigs, the CMT Mortising Bit is an excellent choice for professional woodworkers and hobbyists who demand accuracy, durability, and consistent results. CMT orange router bits have been rated the #1 overall router bits compared to other brands by Wood Magazine.

  • 1/2 in. cutting diameter with 3/4 in. cutting height and 2-9/64 in. overall length.
  • Two high-density carbide cutting edges provide long-lasting sharpness and reliable performance.
  • Negative shear angle design reduces tear-out and produces cleaner cuts.
  • Creates smooth-bottom mortises for hinges and hardware installation.
  • Works with natural hardwoods, softwoods, and wood composite materials.
  • Fits most popular mortising jigs for versatile routing applications.
  • Ideal for hinge mortising, template work, and sign-making projects.

Safety Tips

Always wear a dust mask and eye protection when routing.

Safety Precautions

Never use damaged or worn router bits. Always operate at the recommended feed rate without forcing the bit. When making initial cuts with small diameter bits, use caution and make multiple passes for the best results.

How CMT Produces High-Quality Router Bits

  • Turning, Milling, and Cutting: CMT uses advanced automated CNC machinery operated by specially trained technicians to produce router bit bodies and shanks with exceptional accuracy and balance.
  • Heat-Forged Steel Bodies: Larger diameter bits may undergo a heat-forging process that creates a radial grain structure for increased strength, durability, and resistance to demanding cutting conditions.
  • Precision Brazing: CMT’s custom-designed brazing process creates a strong carbide-to-steel bond using a silver-copper-silver brazing system that helps absorb shock and protect carbide tips during heavy cutting.
  • Application-Specific Carbide: CMT formulates carbide grades for specific woodworking applications, balancing hardness and durability to provide optimal performance across a wide range of materials.
  • Grinding and Sharpening: Final sharpening is completed on multi-axis CNC grinding machines to achieve precise cutting edges and consistent performance.
