Silver & Deming Drill Bits

Silver and Deming drill bits are large size bits with reduced shanks that are ideal for situations where a bit diameter is greater than the capacity of a drill chuck. This Silver and Deming drill bit is also known as a reduced-shank drill bit. The HSS drill bits provide good wear resistance and can be used in general purpose applications on both ferrous and nonferrous materials. Oxide coating of these bits prevents chip building, galling, and welding on the workpiece. Its black-gold surface treatment holds lubricant for smoother, longer drilling. It is ideal for drilling steel, stainless steel, cast iron, titanium, manganese, and other tough materials.
