Our 1321 Hammer's drill-thru feature permits simultaneous drilling and driving of 6" to 24" casing. A single mechanical valve controls the air distribution, which results in a very reliable and precise operation.

No unnecessary complexity as used by our competitors, no chains to snap or springs to break; and more importantly, no leak-prone hydraulics that can contaminate your well.
