Schramm Hammers and Bits

Universal Performer • High Sample Recovery • Deep Hole Reliability • Easy Maintenance • Guaranteed to 1,000 PSIG

Offering the highest air efficiency, Schramm reverse circulation hammers are designed to increase energy transmission where it counts at the bit face. As a result, they drill faster, giving you more feet per day at significantly lower cost. In addition, the inner tube is hardened, top loading and removable without hammer disassembly. Adapter subs are available for a wide range of standard configurations. Hammers are guaranteed for 1,000 psi operation.

Universal Performer: Proven in the field to be consistent high performers in all conditions
High Sample Recovery: Chip sizes large enough to satisfy the requirements of the most demanding Geologists. Extensive field testing shows that the sample travels freely to the cyclone without blocking the bits or the hammer. More importantly, the bit face is designed to clear samples with minimal regrinding
Deep Hole Reliability: Maximum CFM through the hammer with optimal psi clears water and returns a dry sample. The Schramm Hammer has been proven to avoid silting or blocking even in the deepest exploration holes, while still maintaining efficient penetration
Handles Changing Ground Conditions: Easily handles running sands, clays, broken ground, hard rock and the difficulties experienced in iron ore exploration
Easy Maintenance: Compared to its competitors, the Schramm Hammer has the least number of parts. Designed for simple and easy maintenance in the field it can be quickly broken down and serviced within minutes
Warrantied to 1,000 psig
