Draper Expert 34757 HSS Bi-Metal Hole Saw Blade 33mm

This heavy‑duty, high‑speed variable pitch bi-metal hole saw is designed for clean, accurate cutting of round holes in metals, plastics, wood, and other materials. It supports cutting depths up to 35 mm (1.3/8 in) and is built for durability and long‑lasting performance. The cutting edge is hardened M3 steel welded to a tough alloy steel body, reducing the risk of shattering during use. Suitable for heavy‑duty applications, it can be attached to standard power drills for efficient operation. The tool includes four side slots for slug removal, a female threaded spindle for fixing to a 9.5 mm arbor, and compatibility with standard drill setups. An optional metal cutting lubricant is available to help prolong tool life. The hole saw is described in variations of size and color, reflecting its design for solid performance across materials such as wood, steel, brass, bronze, cast iron, aluminum, and plastic.
