Drill America 47/64in HSS Reduced Shank Drill Bit

The Drill America 47/64in HSS Silver and Deming drill bit features a 1/2in reduced shank that fits standard drill chucks while drilling larger holes. Its high-speed steel construction with surface-treated flutes suits general-purpose metal, wood, and plastic drilling tasks in maintenance, fabrication, and automotive shops.

Sustained-load performance with HSS construction

High-speed steel retains hardness at elevated temperatures generated during continuous drilling, reducing the risk of premature wear compared with uncoated carbon steel. The surface-treated flutes promote chip evacuation and lower friction, helping the bit maintain cutting efficiency through repeated or deep-hole operations.

Questions about this item

How much heat builds up when drilling with the 47/64" Silver and Deming bit all day?

High-speed steel with surface-treated flutes helps dissipate heat during extended drilling, but the bit will still warm up; use cutting fluid and periodic pauses to manage temperature on long jobs.

What drill chuck is required for the 1/2" reduced shank on this bit?

The 1/2" reduced shank fits any drill with a 1/2" or larger chuck capacity, so you need a drill that accepts at least a 1/2" shank to use this Silver and Deming bit.
