1-3/8" Cobalt Silver and Deming Drill Bit

This Drill America bit is a 1-3/8 inch cobalt steel drill accessory with a reduced 1/2 inch shank designed for use in pneumatic or power drill chucks. The bronze oxide surface treatment on the flutes helps resist wear during heavy-duty metal drilling tasks. It suits maintenance technicians and fabricators who need a single large-diameter bit compatible with standard 1/2 inch capacity chucks. The decimal equivalent is 1.3750 inches.

Reduced shank fits standard half-inch chucks

The reduced shank allows this large-diameter bit to be secured in any 1/2 inch drill chuck without requiring a specialised large-capacity holder. Its 3 inch flute length and 6 inch overall length provide deep-hole reach while the cobalt steel construction maintains hardness at elevated temperatures. Builders needing multiple hole sizes or a quick-change system will need additional bits or a different chucking solution.

Highlights

  • Cobalt steel resists heat during heavy drilling
