Sandvik is introducing a new drilling tool system, the Alpha 360, which it says is an improved and amplified version of the company’s best-selling Alpha 330 top hammer system (pictured).

With a reinforced design, Alpha 360 can last twice as long as a standard industry thread. Its hole accuracy also enables higher productivity in tunneling and mine development, according to Sandvik.

The system has been developed to deliver “unprecedented rock tools performance” and, at the same time, boost productivity in the whole drill-and-blast cycle, Sandvik said.

Robert Grandin, Product Manager for Underground Top Hammer, at Sandvik Rock Tools, said: “Alpha 360 is yet another example of our aim to provide customers with products that will maximise the output of their investments.

“High drilling accuracy is crucial to ensure that the tunnel gets the desired direction and profile. Straight and parallel holes also improve the advance per blast.”

The Alpha 360, which is designed for Ø48-51-mm-hole sizes in face drilling and bolting, features a strong thread design. The short thread on the round rod gives superior resistance towards bending stresses, improved bit guidance and excellent energy transfer, according to Sandvik.

The sturdy thread is guided inside the bit skirt, which enables high precision collaring also in complex rock formations and against uneven surfaces.

Grandin said: “As a leading supplier to the rock drilling industry, Sandvik continues to drive the technology forward. We always offer a full drill string from shank adapter to bit, designed for excellent reliability, performance and longevity.”
