Get Maximum Drilling Metres from Every Rod with Kenella

Harlen Supplies helps mines push maximum drilling meters out of the rod by focusing on total meters drilled and extending the life of the rod using our Kenella Rubber Collared Drill Steel; the premium choice in mining consumables built for tough underground conditions.

Why Kenella Rubber Collared Drill Steel Delivers More Total Metres

Kenella Rubber Collared Drill Steel is manufactured from high-quality, non-carburized steel for durability and consistent performance in mining environments. When used with water during the drilling process, the rubber collar helps reduce operating temperature and minimise wear, translating into significantly longer tool life and improved reliability, exactly what drives more metres per rod. Beyond temperature control, the rubber collar also reduces vibration transfer and stress concentrations, helping limit collar micro-cracking and thread wear; key failure points that shorten the rod life.

How Many Metres Can You Get Out of a Rod?

Rod life is site-specific: rock abrasiveness, impact energy, rotation speed, flushing efficiency, and handling all materially affect total metres drilled. In comparable short-hole tapered drilling, manufacturer field feedback commonly reports roughly ~80–200 metres per rod, depending on material grade and ground conditions your goal is to consistently reach the top end by controlling heat, vibration, and wear.

Kenella Rubber Collared Drill Steel is available in 11° taper, 22 Hex or 25 Hex, with lengths from 0.8 m to 3.2 m — ready to match your mining application and maximise cost-per-metre performance.
