Kenella

This article outlines how Kenella drifter drill steel paired with R32 threaded bits is used to manage vibration, protect threads, and sustain consistent drilling performance in harsh African operating conditions.

In underground and surface drilling, tooling failure is rarely a “bad batch” problem. It’s usually a mismatch between ground conditions, impact energy, flushing, and how the drill string manages vibration and wear. When rock is fractured, abrasive, or wet, drill steel and bit selection directly affects penetration, hole quality, and the cost per metre.

Kenella drilling and rock‑breaking solutions, proudly distributed by Harlen Supplies, set the benchmark for performance and reliability across quarrying, mining and construction applications.
