Connect Hole Shot Saws to your drill with the Kango 32-175mm Hole Shot Arbor with Cobalt Pilot Bit. This Arbor is compatible with Kango Hole Shot Carbide and Bi-Metal Hole Saws in sizes ranging from 32-175mm. Tool-free changing enables you to quickly switch between different Hole Saw types and sizes. The 7/16” hex shank reduces chuck slippage and enables a more controlled and precise drilling action. The included M35 Cobalt Pilot Bit’s drilling capabilities are designed to match Carbide Teeth Hole Saws. It’s capable of drilling into stainless steel, hard metals, cement sheet, timber and plastic. The Pilot Bit’s 5% cobalt alloy can withstand extreme levels of heat and abrasion from drilling into stainless steel and hard metals. Its 135° split point prevents wandering which supports precision starts and faster start-up speeds.
