1.11 in. Reduced Shank HSS Drill Bit

The Drill America DWDRSD1-7-64 is a silver and deming drill bit made from high-speed steel with surface-treated flutes. Its reduced shank design allows use in chucks with smaller capacity while drilling larger holes. The bit measures 1.1094 inches in decimal equivalent and comes as a single unit. It suits machinists and maintenance technicians who need to enlarge existing holes in metal.

Sustained drilling performance

Surface-treated flutes improve chip evacuation and reduce friction during continuous cutting, helping the bit maintain its edge over long cycles. The 3-inch flute length provides adequate space for swarf removal when drilling deep into workpiece material. High-speed steel construction resists heat buildup better than carbon steel during extended operation. The 6-inch overall length offers reach for deeper applications without excessive deflection.

Questions about this item

How much heat does the 1.1094 in. bit generate during continuous drilling?

High-speed steel dissipates heat well, but prolonged use at high speed will warm the bit; use cutting fluid and pause occasionally to keep temperatures manageable.

What chuck size is required to hold the 0.5 in. reduced shank?

A drill with a 0.5 in. or larger chuck capacity is needed to secure the reduced shank on this bit.
