M35 HSS Twist Drills – High Cobalt Drill Bits for Hard Metal Drilling | Shanghai Easydrill
Core Advantages of Shanghai Easydrill M35 HSS Twist Drills
- 5% Cobalt Heat Resistance
With cobalt alloy composition, bits withstand high friction heat generated during stainless steel drilling; no softening or edge dulling under continuous high-speed work.
- Ultra Hard Cutting Edge
Fully ground spiral flutes + precision point grinding deliver sharp penetration, lower drilling pressure and less workpiece deformation.
- Long Service Lifespan
Outlasts regular M2 HSS drills by 2–3 times on stainless steel, chrome steel and high-tensile alloy steel, cutting tool replacement costs.
- Anti-Break Uniform Structure
Complete stress relief heat treatment eliminates internal material stress, resisting bending or fracture under heavy load drilling.
- Wide Machine Compatibility
Works with bench drills, hand electric drills, CNC machining centers, lathes and magnetic drill presses.
- Custom & Bulk Supply Support
Shanghai Easydrill offers single sizes, mixed drill sets, private logo printing and custom packaging for global distributors.
