7/8" HSS Reduced Shank Drill Bit
The Drill America Silver and Deming bit is a high-speed steel cutting tool designed for general-purpose drilling in metal, wood, and plastic. Its 1/2-inch reduced shank allows secure chucking in standard drill presses and large hand drills. Surface-treated flutes improve chip evacuation and reduce friction during operation. This accessory suits maintenance technicians and fabricators who need a single large-diameter hole maker.
7/8-inch capacity with 3-inch flute length
The bit creates a precise .8750-inch diameter hole with a flute length of three inches and an overall length of six inches. It handles through-holes in thick plate or deep blind holes in softer materials. The reduced shank limits use to chucks that accept 1/2-inch diameters, so it will not fit smaller 3/8-inch drill chucks. Buyers needing diameters larger than 7/8 inch or shank sizes smaller than 1/2 inch must select a different tool.

Questions about this item
Will the 1/2in reduced shank fit the chuck on my older 1/2in capacity drill press?
The reduced shank is sized at 1/2in so it seats directly in any standard 1/2in chuck without an adapter.
How can I confirm the bit is cutting true after I clamp it in the press?
Run the bit at low speed and watch the .8750 diameter cut; a steady, centred hole with no wobble shows it is running true.
