About this item
- 【Set Contents】This hole saw set includes 13 high-performance hole saw cutters in common metric sizes: 18, 20, 22, 25, 28, 30, 35, 38, 45, 50, 55, 60 and 75 mm. Boasting an effective cutting depth of 30–35 mm, this complete set easily satisfies most daily maintenance, DIY projects and professional drilling requirements for various materials.
- 【Premium Material】Bi-metal hole saw set crafted from heat-treated carbide steel with premium M42 alloy construction, this bi-metal hole saw delivers 65–66HRC hardness, outperforming conventional alloys in toughness and rust resistance. Reinforced with a high-speed steel coating, the cutting teeth boast enhanced hardness and wear resistance for superior cutting performance.
- 【Efficient & Precise Cutting】These wood hole saw sets feature optimized high-speed steel blades for clean, smooth, highly efficient cuts. With carbide-infused hardness and impact-resistant teeth, diameter deviation is within 1mm. Angled grooves and chip holes clear debris, reduce heat, and extend service life. The smooth-edge design ensures easy operation, while the spring-loaded bit automatically ejects cores.
- 【Wide Application】This hole saw bit set is ideal for drilling into metal steel, castings, aluminum alloys, plastic sheets, galvanized pipes, fire hoses, various wood, and gypsum boards. Hole cutter works perfectly with bench drills, drill presses, gun drills, and all types of electric hand drills, suitable for both professional and daily drilling tasks.
- 【Important Usage Notes】This metal hole saw cutter requires controlled rotation speed (≤1000 RPM) during prolonged use to prevent excessive wear. Hole drilling cutter features a thin protective oil coating for oxidation and rust resistance, so please avoid staining. Regularly inspect the circular drill bit’s condition to ensure safe, stable operation.

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.
