  • 28” Diameter Star Cross Four-Wing Chisel Bit for Cable Tool
  • Used
  • For drilling 28" irrigation wells, elevator shafts, and other large diameter holes in clay and other geological formations. 
  • Supposedly the "cross" or "star" with the 4 cutting edges helps bits like this drill straighter in slanted formations. 
  • Although a special purpose bit, drillers could use it every day in some geologies and conditions.
  • Presumably American manufactured with carbon and/or alloy steels, but unsure if this is Acme, Spang, Gill Rock Drill, Ideco, Trident, Rampp, O.W.S. Co., Keystone or maybe another historical tooling manufacturer.
  • If you require thread protector(s) on tool joint(s) add another $15.
  • Located in Mifflinburg, PA USA
