Handheld tapered equipment

For underground and dimensional drilling.

These days, tapered is favoured

Increased penetration rate, longer service life and lower drilling costs. With benefits like these, it’s easy to see why tapered equipment is grabbing market share from integrals – especially in mining applications and the dimensional stone industry.

Bits with bite

Our bit design and production processes are also in a state of constant refinement. The Secoroc Uppercut range comprises button and cross-type bits in an extensive selection of design configurations. Moreover, we’ve added two new models with an extra front button for improved hole straightness, higher penetration rate and a longer service life. These designs can be used in a variety of rock formations for maximum productivity.

At your service

Your tapered equipment will need care and maintenance to stay productive over its service life. Bits have to be reground at regular intervals to crush rock efficiently. Armed with a Secoroc grinder, your tools will stay on the cutting edge. Moreover, thanks to the global reach of Atlas Copco’s service network, know-how and support are never more than a phone call away.

Tapered equipment

   


Tapered rods

Tough rods for a tough life
Atlas Copco Secoroc tapered rods are renowned for their superior fatigue strength and resistance to bending stress. With the launch of the Uppercut range, we’ve increased fatigue resistance still further. Thanks to a unique heat-treatment process, the internal stresses of the steel are released, while high durability is retained. The result is a tapered rod that’s better able to handle the strain of 7–10 kW rock drills.
