BESTWiN TOOLS

The BESTWIN M42 bimetal hole saw is engineered for professionals who demand maximum durability, speed, and precision across multiple materials. Unlike standard options, this high-performance solution features a specialized cobalt alloy bimetal construction and a unique tooth profile designed for the fastest cutting and a smooth, burr-free surface finish.


Efficiency and longevity are built into the design. The innovative chip groove and additional release holes allow for rapid chip discharge and easy core ejection, preventing cracking or jamming during heavy-duty use. This versatile system is optimized for both corded and cordless power tools, ensuring high concentricity accuracy and uniform tooth wear. Whether you are drilling through steel, wood, plywood, or non-ferrous metals, these metal hole saws provide a reliable, long-lasting solution.
