Silver & Deming Drill Bits

Premium Reduced Shank Drill Bits for Industrial-Grade Performance

Silver and Deming drill bits feature a 1/2" reduced shank, allowing them to fit in standard drill chucks without the need for special tools. Built for drilling large holes in metal, wood, and plastic, these bits offer reliable performance in demanding industrial settings.

Why Choose Reduced Shank Drill Bits?

Reduced shank drill bits allow for drilling wider holes while using standard-sized chucks—especially useful when your tool’s chuck size is smaller than the drill bit diameter. You get more range with fewer tools. These bits are ideal for applications where fewer tool changes increase productivity.

What Is a Silver and Deming Drill Bit?

A Silver and Deming drill bit is a large-diameter drill bit with a 1/2" shank, regardless of its cutting diameter. These bits typically range from 9/16" to 1-1/2" in diameter. Originally named after a 19th-century manufacturer, they remain a go-to for machinists and metalworkers.

Frequently Asked Questions

What is a Silver & Deming drill bit?
A Silver & Deming drill bit is a large bit—often starting at 9/16" diameter—with a 1/2" reduced shank. This allows it to fit into standard drill chucks.

What are Silver & Deming drill bits used for?
They are used for drilling larger holes in metal, wood, or plastic where a standard-sized chuck is used. They’re common in metalworking and woodworking.

Can Silver & Deming drill bits be used in a handheld drill?
Yes, they can. As long as the drill has a 1/2" chuck, these bits will fit. However, due to their size, a drill with high torque is recommended.

What materials are suitable for Silver & Deming drill bits?
They can drill through steel, aluminum, wood, PVC, and other soft or composite materials, depending on the bit’s composition (HSS, cobalt, etc.).

How do I choose the right size and speed/feed rate?
Refer to material-specific drilling charts. As a general rule, larger bits require slower speeds. Use cutting fluid when drilling metal to extend tool life.
