Product details

Engineered for applications demanding exceptional dimensional accuracy, this M35 HSS Hole Saw delivers blade runout of ≤0.04mm and hole diameter tolerance of ≤±0.08mm, ensuring perfectly round, smooth, and burr-free holes. With perpendicularity controlled to ≤0.02mm/m, it eliminates the need for secondary finishing, making it ideal for precision installations in hardware, pipelines, and electrical appliances. The robust M35 high-speed steel construction provides excellent red hardness and wear resistance, while the versatile design accommodates diameters from 18mm to 120mm. Suitable for drilling stainless steel, cast iron, carbon steel, concrete, ceramic tiles, marble, granite, and glass (with auxiliary cooling), this hole saw is a trusted choice for industrial manufacturing, construction decoration, mechanical maintenance, and hardware installation.

Product Features & Advantages

Core Material Science: The Cobalt Advantage

Unlike standard HSS drills (like M2), our bits are formulated with a significant cobalt infusion. This alloying element fundamentally increases the steel's hot hardness (red hardness), allowing the cutting edge to retain its temper and sharpness under intense frictional heat generated when drilling tough materials.

Engineered for Peak Performance

Designed for continuous high-temperature drilling applications, this M35 Cobalt HSS Hole Saw delivers exceptional heat and wear resistance, outperforming ordinary HSS drills by 2 to 5 times in service life. The cobalt-enhanced matrix provides superior edge strength, resisting chipping and deformation even under heavy feed pressure. When machining gummy materials such as stainless steel or certain alloys, the material composition naturally minimizes built-up edge (BUE) , ensuring cleaner holes and smoother operation. Each bit undergoes a full grinding process, achieving precise dimensional accuracy with h8/h9 tolerances, a superior surface finish, and consistent point geometry for immediate, chatter-free penetration. Ideal for demanding industrial and construction environments.
