Product details

material: High-quality cemented carbide (WC-Co grade), with HRC 88-90 hardness rating and tungsten carbide content up to 90%, combined with a tough steel substrate, integrating ultra-high hardness and excellent impact resistance, which is far superior to high-speed steel in cutting hard materials.Precision cutting edge: The carbide teeth are precision ground and brazed to the steel substrate with high-temperature vacuum brazing technology, ensuring firm bonding without falling off. The teeth adopt a 12° positive rake angle and 5° clearance angle, reducing cutting resistance and enabling smooth, burr-free cutting of high-hardness materials.Sharpness retention: Maintains stable cutting performance for up to 120+ hours of continuous use on hard materials such as stainless steel (≤5mm), cast iron, concrete, ceramic tiles and stone, effectively resisting wear and dulling caused by high-speed friction and hard material impact, and its service life is 3-5 times that of high-speed steel hole saws.

The blade runout ≤0.04mm, the hole diameter tolerance ≤±0.08mm, ensuring that the drilled hole is round, smooth and free of burrs, with high perpendicularity (≤0.02mm/m), no need for secondary polishing, suitable for high-precision installation scenarios such as hardware, pipelines and electrical appliances.Versatility: Available in multiple specifications (diameter 18mm-120mm), suitable for drilling holes in stainless steel, cast iron, carbon steel, concrete, ceramic tiles, marble, granite, glass (with auxiliary cooling) and other hard materials, widely used in industrial manufacturing, construction decoration, mechanical maintenance and hardware installation.

Engineered for Peak Performance

Exceptional Heat & Wear Resistance: Performs reliably in continuous high-temperature drilling scenarios, outlasting ordinary HSS drills by 2-5 times.
