Sandvik says its new drilling tool system Alpha 360 is a reinforced and amplified version that complements the company’s Alpha 330 system. It can last twice as long as a standard thread in the industry. Its hole accuracy also enables higher productivity in tunneling and mine development, says Robert Grandin, product manager for underground top hammer, at Sandvik Rock Tools.

The Alpha 360, with its strong tread design, is designed for hole diameters of 48-51mm in face drilling and bolting. The short thread on the round rod gives superior resistance towards bending stresses, improved bit guidance and excellent energy transfer.

The sturdy thread is guided inside the bit skirt to allow high-precision collaring also in complex rock formations and against uneven surfaces.

Sandvik claims that its Speedy Bit is the fastest drill bit in the industry. In addition to 10% higher drilling speed, it delivers great collaring accuracy and hole quality.

By increasing the drilling speed with up to 10% compared to a standard bit with ballistic buttons, Sandvik says that Speedy Bit can save users one hour per day for each drill rig which can translate into more than US$100,000 per year and drill rig.

Speedy Bit features one of Sandvik’s new PowerCarbide grades and outperforms the standard bits in the industry with aggressive buttons that penetrate deeper with each strike and increase cutting size. The elevated front breaks the rock in two levels and improves the flushing flow, while large sludge grooves enable quick removal of large cuttings.

Sandvik Speedy bits are available in three dimensions: 45, 48 and 51mm.
