CMT Mortising Bit, 1-1/4 in. Dia., 1/2 in. Shank
CMT Mortising Bit, 1-1/4 in. Dia., 1/2 in. Shank
Designed with thick carbide tips and a negative shear angle for clean, precise mortising performance.
CMT mortising bits deliver smooth, accurate cuts for hinge mortises, template routing, sign making, and other detailed woodworking applications. The advanced cutting geometry produces clean edges with minimal splintering and smooth bottoms in both natural wood and composite materials. These bits fit most popular mortising jigs, making them a versatile choice for professional and hobbyist woodworkers.
CMT orange router bits have been rated the #1 overall router bits compared to other brands by Wood Magazine.
- 1-1/4 in. cutting diameter with a 3/4 in. cutting length and 2-9/64 in. overall length.
- Features 2 high-density carbide cutting edges with a negative shear angle design for extended cutting life.
- Creates precise hinge mortises without splintered edges or rough bottoms.
- Designed for use in natural wood and wood composite materials.
- Compatible with most popular mortising jigs.
- Ideal for template work, sign making, and detailed woodworking projects.
Safety tips: Always wear a dust mask and eye protection when routing.
Safety precautions: Never use damaged or worn bits. Always operate at the recommended feed rate and avoid forcing the bit through the material. When using small diameter bits, take special care during the initial cut. For best results, make deeper cuts in multiple passes.
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 and boring bits with precise dimensions, accurate shanks, and excellent balance.
- Heat-Forged Steel Bodies for Large Diameter Bits: Larger diameter bits receive additional manufacturing steps, including heat forging, to create a stronger radial grain structure for improved durability and performance.
- Brazing: CMT's custom-designed computerized brazing process creates a consistent bond between steel bodies and carbide tips. The silver-copper-silver brazing construction provides shock absorption to help protect carbide edges during demanding cuts.
- Specially Formulated Carbide for Specific Applications: CMT engineers carbide compositions for specific woodworking tasks, balancing hardness and impact resistance to achieve reliable performance across a wide range of materials.
- Grinding and Sharpening: Final sharpening and grinding operations are completed on multi-axis CNC machines to ensure precise cutting edges and consistent performance.
