Introducing our 20mm Bi-Metal M42 High-Speed Steel Hole Saw with Pilot Drill Bit—the ultimate cutting companion for Australian DIY enthusiasts and professionals alike. Whether you're tackling plumbing, electrical work, HVAC installations, or home improvements, this hole saw delivers precision and durability you can rely on.
Constructed from premium M42 bi-metal high-speed steel, this hole saw offers outstanding hardness, heat resistance, and wear resistance. The cutting teeth, made from M42 high-speed steel with a hardness of ≥65 HRC, remain sharp even at high temperatures, while the flexible bi-metal body withstands long-term high-speed operation without deforming. This combination ensures a longer service life, smoother cuts, and higher efficiency when drilling through hard and thick materials.
We've optimized the design with a multi-hole feature and a spring-guided pilot drill. After drilling, the cutting disc automatically ejects, significantly improving chip removal and reducing clogging, especially when working with thick or hard materials. This innovation provides a smooth user experience, saving you time and effort on every project.
Using this hole saw is effortless. Clear size markings allow for quick selection of the right tool, while the universal shank is compatible with most electric and cordless drill chucks. It ensures fast installation, a secure clamp, and stable torque transmission, minimizing the risk of slipping under high loads. This hole saw is suitable for drilling holes in a wide range of materials, including:
Ideal for plumbing, electrical engineering, HVAC installations, or any home DIY project, this hole saw is a versatile addition to your toolkit.
