1.19 in reduced shank cobalt drill bit

The Drill America DWDCO1-3-16 is a single cobalt steel drill bit with a 1.19 inch diameter and a reduced shank for use in standard half-inch chucks. Its heavy-duty notched point is designed to start accurately in hard metals such as stainless steel and titanium alloys. The bit offers a three-inch flute length and six-inch overall length for deep-hole drilling tasks. Industrial maintenance crews and metal fabrication shops will find it suited for high-heat, high-wear applications.

Check shank compatibility and workpiece thickness

Verify that your drill chuck accepts a half-inch reduced shank before ordering. The three-inch flute length limits the maximum drilling depth in a single pass, so confirm the workpiece thickness matches this reach. Cobalt steel performs best with cutting fluid and rigid machine setups; hand-held drilling in thin sheet metal may cause the bit to grab or chatter. Buyers who need a full 1.1875 inch shank or a longer flute should select a different bit.
