General description Tungsten Carbide Hole Saw is a great alternative to the traditional bi-metal hole saw. They cut faster, cleaner, and last longer, making them ideal for various applications including electrical construction, transit work, and general metal fabrication. The spring-loaded pilot tip ejects the cut slugs, saving time and ensuring a clean, burr-free hole. Technical specifications Diameter: 1-15/16' (50mm) Material: Tungsten Carbide Usage Designed for cutting through steel plate, iron, aluminum, copper, cast iron, and especially stainless steel and other hard alloys. Normal maintenance extends tool life significantly compared to other hole cutting tools. Inexpensive sharpening allows for repeated use.
