CMT Mortising Bit, 1/2 in. Dia., 3/4 in. Cutter, with Bearing, 1/4 in. Shank
CMT Mortising Bit - 1/2 in. Dia. x 3/4 in. Cutter Height with Bearing - 1/4 in. Shank
Precision mortising performance with thick carbide tips and a negative shear angle design for clean, splinter-free cuts.
CMT mortising bits deliver flawless results for hinge mortises, template routing, sign making, and other detailed woodworking applications. Designed with thick carbide tips and a negative shear angle, these bits produce smooth cuts with clean edges and flat bottoms in both natural wood and wood composites.
The integrated bearing allows for accurate template work, while the compact design fits most popular mortising jigs. CMT orange router bits are recognized for their exceptional performance and have been rated the #1 overall router bits compared to other brands by Wood Magazine.

Safety Tips
Always wear a dust mask and eye protection when routing. Never use damaged or worn router bits. Use the recommended feed rate and avoid forcing the bit through the material. When working with smaller diameter bits, make multiple passes to achieve the best results and extend tool life.
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, balance, and consistency.
- Heat-Forged Steel Bodies: Large diameter bits receive additional heat-forging treatment to create a radial grain structure that improves strength, durability, and performance.
- Advanced Brazing Technology: CMT's computerized brazing process creates a strong bond between the steel body and carbide tips. The silver-copper-silver brazing system provides shock absorption to help protect carbide edges during demanding cuts.
- Application-Specific Carbide: CMT formulates carbide grades specifically for different woodworking applications, balancing hardness and impact resistance for maximum cutting performance.
- Precision Grinding and Sharpening: Multi-axis CNC grinding machines sharpen each cutting edge to precise specifications, producing razor-sharp edges with long-lasting durability.
