Silver & Deming drills are large-diameter bits (typically 1/2″ and up) with a shank reduced to 1/2″ so they fit a standard drill chuck. They’re the classic solution for drilling big holes in steel and other metals without an industrial drill.

Rugged high-speed steel construction stands up to heavy shop use. Browse our full range of over-1/2″ sizes.
