9/16" Reduced Shank Cobalt Drill Bit
This Drill America bit is a Silver and Deming style accessory built for heavy-duty drilling in metal. Its cobalt steel construction handles high heat and abrasion when working with stainless steel, cast iron or tough alloys. The reduced 1/2" shank allows the 9/16" cutter to fit standard drill chucks and pneumatic drivers. It is suited for professional mechanics and fabricators who need a single large-diameter bit for thick plate work.
Bronze Oxide Flutes and 6" Overall Length
The bronze oxide surface treatment on the flutes reduces friction and resists corrosion during extended use. A 3" flute length provides adequate chip clearance for deep holes while the 6" overall length offers reach into recessed areas. The straight-shank design suits keyed or keyless chucks without a taper requirement. Buyers who need a full Silver and Deming set or a bit with a tang drive will not find those features here.

Questions about this item
What does the 1/2 in reduced shank cap the maximum drill-chuck size at?
The reduced shank measures 1/2 in, so it fits any chuck that accepts at least that capacity.
What overall length and flute length must the drill press or hand drill accommodate?
Overall length is 6 in with a 3 in flute, so the spindle travel and workpiece clearance must allow at least that depth.
