Overview:

Larger Size Hole Saw Arbor and Pilot Drill Bit a heavy-duty threaded arbor designed to drive larger hole saws from 32mm to 175mm (1-1/4" to 7"), making it ideal for bigger cut-outs in timber, plastics and sheet materials when used with suitable bi-metal hole saws. Built from hardened steel for strength and long service life, it features a universal quick-change style that works across many hole saw brands without the need for additional adaptors. Supplied with a 6mm (1/4") HSS pilot drill, it helps you start cuts accurately and keep the hole saw centred for cleaner results. Finished with a black oxide body and a dry rust-resistant coating, it’s a reliable arbor for workshop and site use.
