Premium Large Diameter HSS 1/2″ shank Silver & Deming Drill Bit
Can be used in any 1/2″ drill chuck.
When you need to drill holes larger than your drill chuck can normally accept, Silver & Deming drill bits are the professional solution. These premium M2 High Speed Steel drill bits feature a 1/2″ reduced shank, allowing large diameter drilling in virtually any drill press or hand drill equipped with a standard 1/2″ chuck.
Manufactured from premium M2 High Speed Steel, these drills provide dependable performance and long service life in general-purpose drilling applications. The three-flat shank design helps minimize slippage under heavy torque while providing a more secure grip in keyed and keyless drill chucks.
