Standard design – Ideal for water well drilling, blast hole drilling and civil engineering projects.
HD design – Designed for abrasive and demanding applications. The HD hammer features a larger overall diameter, in turn allowing for thicker walls and, ultimately, a longer service life. It’s also equipped with reversing back-out buttons, protecting the top sub from wear.
Slim design – The Slim version is designed for non to medium-abrasive formations, using a smaller bit diameter than recommended for the standard hammer OD. The Slim design allows an oversized hammer to drill the hole, thereby optimizing performance.
