Used
For drilling difficult rock earth formations with water well cable tool drill rig truck.
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.
