Our factory manufactures M35 cobalt-containing ground high-speed steel double-ended twist drills, specifically designed for stainless steel processing. The M35 cobalt-containing high-speed steel base material endows the drills with excellent high-temperature hardness and wear resistance, enabling them to tackle issues like chip adhesion and overheating that commonly occur in stainless steel processing, thus ensuring stable cutting performance. Processed via precision grinding, the drills feature enhanced cutting edge sharpness and dimensional accuracy, with optimized chip flute structures to reduce chip accumulation. The double-ended design allows for bidirectional use, extending single-service life, improving tool utilization, and reducing replacement frequency. These drills are suitable for drilling operations on stainless steel plates, pipes, etc., and also applicable to processing other high-strength alloy materials. Relying on mature material control and grinding technologies, our factory ensures stable product performance, providing efficient tool support for stainless steel processing scenarios.
