Draper HSS Bi-Metal Hole Saw Blade 108mm

This high-speed bi-metal holesaw is designed for precise and clean hole cutting in metals, plastics, and wood up to a maximum depth of 35mm (1.3/8”). It combines a hardened M3 steel cutting edge welded to an alloy steel body to deliver long-lasting performance and reduce the risk of shattering in heavy-duty applications. The tool features a variable pitch design for smooth cutting and provides accurate results across a range of stubborn materials. Four side slots enable slug removal during operation, and the saw is compatible with standard arbors that use a 9.5mm (3/8”) spindle. For metal cutting, a compatible lubricant can be used, and installation involves attaching the holesaw to a compatible arbor and securing it for use with power drills.
