About this item
- 【Top-Tier Durability】Crafted from premium M42 alloy, our bi-metal hole saw boasts a surface that outperforms conventional alloys in toughness. With an impressive hardness rating of 65–66HRC, it delivers long-lasting durability and reliable rust resistance. The cutting teeth are reinforced with a high-speed steel coating, boosting hardness and wear resistance for exceptional cutting performance.
- 【Swift & Precise Cutting Performance】Carbide-infused construction boosts our hole drilling cutter’s hardness, while precision-engineered tooth geometry enables ultra-fast cutting. Its high-speed steel blade features impact-resistant teeth that prevent tooth loss, delivering accuracy far superior to standard models with diameter deviation under 1mm.
- 【Effortless Operation】Our hole opener kit features a smooth-edge design for unimpeded, rapid cutting. Upgraded chip evacuation holes clear debris instantly to prevent jamming and workpiece cracking. The built-in spring-loaded drill bit automatically ejects the core disc right after drilling—no extra effort required.
- 【Broad Compatibility】Our hole saw drill bit works seamlessly on wood, plastic, mild steel, stainless steel, cast iron, bronze, copper and aluminum. It’s also ideal for drilling holes for can lights, recessed lighting, air ducts, ceiling fixtures and speakers. Compatible with bench drills, drill presses, gun drills and all types of hand drills.
- 【Metal Hole Saw Assortment】This kit includes 13 metal hole saw cutter with diameters spanning 18–75mm (18, 20, 22, 25, 28, 30, 35, 38, 45, 50, 55, 65, 75mm), meeting most daily and professional aperture requirements. It offers an effective cutting depth of 30–35mm. For extended use, maintain a rotation speed ≤1000 RPM to prevent excessive high-speed wear and prolong tool lifespan.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
