Draper 34760 HSS Bi-Metal Hole Saw Blade 46 mm

These high-speed, variable pitch bi-metal hole saws are designed for precise and clean cutting of round holes in metals, plastics, and wood up to a maximum depth of 35 mm (1.375 inches). Constructed with a hardened M3 steel cutting edge welded to a tough alloy steel body, they are durable and resistant to shattering for heavy-duty applications. The design includes four side slots for slug removal and a female threaded spindle for attachment to a 9.5 mm arbor, enabling secure mounting to compatible power drills. They are suitable for metal cutting as well as wood, plastic, brass, bronze, cast iron, and aluminum. The tool requires a hole saw arbor to complete the assembly and should be used with appropriate drill speeds and lubrication to extend tool life and maintain alignment and steady pressure during operation.
