10” Diameter X 44" Length Heavy Duty Cable Tool Chisel Bit
for approximately 10" diameter boreholes / heavy duty water well cable tool drilling.
Tool joint connection 2 1/4" x 3 1/4" API thread pin.
Around 44” length.
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.
