RC Down Hole Hammers
Hammer bolt together design allows rotation in both directions
Quick change bit technology allow quick access to bit with hand tools without removing hammer from drill string
- Oversized center return allows effective large debris removal for faster penetration
Designed to be easy to take apart and reassemble—using hand tools
Drill Straighter holes—the Bit Shroud design minimizes Bit slip when drilling non-uniform hardness rock
Key drive eliminates unneeded Bit weight and length offering better Piston-to-Bit weight ratio
Bit Shroud keeps cuttings out of the gap between the Bit and Hammer
Check valves at the bottom of the Hammer reduce the possibility of debris from entering
- Carburized center tube spans throughout hammer to minimize wear from cuttings
RC Down Hole Hammer Technology comes from experience. Designing and manufacturing with our customers and industry experts to meet specific job needs, we have been able to incorporate innovative solutions and develop some of the most efficient, durable tooling available. Our large diameter reverse circulation hammers continue to set the benchmark for the industry.
Holte’s Reverse Circulation Grout Through Hammer technology has proven successful in drilling down the hole, then grouting through the bit face on the way out by simply switching a valve.
We can manufacture and heat treat, in-house, any hammer up to 43” (1092mm) to ensure balance between strength and durability of materials.
