Drill America 15/32in Cobalt Extension Bit
This Drill America accessory is a cobalt steel aircraft extension drill bit built for heavy-duty drilling tasks. The split-point design helps reduce walking and improves starting accuracy in tough materials. It suits maintenance technicians and metalworkers who need extended reach for deep-hole applications.
Simple chuck installation
The bit fits directly into compatible drill chucks without adapters or special tooling. Cobalt steel resists heat but can chip if side pressure is applied during deep cuts. Users must clear chips frequently to prevent binding in the 4-5/16 flute length.
