Hard Rock Auger

The Hard Rock Auger from Auger Torque has been designed and engineered to fulfil the most demanding of drilling applications.

Designed for drilling in fractured hard rock and extremely abrasive conditions. Optimised in direct collaboration with operators specialising in hard rock drilling applications we are excited to offer the Hard Rock Auger Range globally.

A perfect choice for excavators between 5-50T, these augers are designed to get the hole drilled when regular rock augers start to refuse. Made to spec from the highest grade steel, we are confident our hard rock auger range will stand up to the toughest of applications time & time again.

    • Tapered Cutting Path

      Our cutting heads are designed with a constant spiral cut. Teeth are located so that each tooth makes its own fresh cut on every revolution and are angled to direct spoil towards the centre of the cutting head. The tooth cutting angle ensures spoil is broken up thoroughly to avoid any clogging.
