Project Description

Reverse Circulation Down The Hole Grout Through Drilling Hammers

Reverse Circulation Hammer Technology is where Holte shows experience. With 30 + years of designing and manufacturing alongside our customers job specific needs we have been able to develop some of the most efficient, durable tooling available that incorporates innovative solutions no other DHH can match.  Our large diameter drill hammers, in fact, continually set the benchmark for the industry, helping you stay one step ahead.

Holte’s patented grout through drill hammers are the only hammers in the world that have proven successful in drilling down the hole, then grouting on the way out by simply switching a valve.

Whether you need a hammer for specific conditions or just a standard design that draws on our past, proven knowledge of drilling you can rely on Holte to work with you and get the job done faster.  We can manufacture and heat treat in house any single piece hammer up to 43” (1092mm) to ensure the ultimate balance between strength and durability of materials.

We also offer Quad (cluster) Drills for even larger hole solutions.
