Sandvik breaks new ground with introduction of industry’s fastest drill bit

Sandvik thinks it has introduced the fastest drill bit in the industry with its new Speedy bit.

In addition to 10% higher drilling speed compared with standard bits with ballistic buttons, the Speedy bit also delivers great collaring accuracy and hole quality, according to the company.

Sandvik said the increased speed enables Speedy bit users to save one hour per day for each drill rig.

Robert Grandin, Product Manager for Underground Top Hammer at Sandvik Rock Tools, said: “Sandvik is continuing to break ground in the drilling business with the introduction of Speedy bit. With increased drilling speed, customers can expect significant cost savings. This can translate into more than $100,000/y.”

He added: “Since drilling faster also reduces machine-related costs per metre advanced, such as for operators and maintenance, the Speedy bit is an excellent example of our aim to always maximise the output of our customers’ investments.”

The Speedy bit, which features one of Sandvik’s new PowerCarbide grades, outperforms the standard bits in the industry with aggressive buttons that penetrate deeper with each strike and increased cutting size, according to Sandvik.

The patented 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 mm, 48 mm and 51 mm.

Grandin said the Speedy bit has proven its performance in the field during more than 20 trials in mine development and tunnelling. “On average, drill speed increased by 9% compared to bits with ballistic buttons, including several regrinds,” he said.

Sandvik offers a full drill string from shank adapter to bit, designed for reliability, performance and longevity. The Speedy bit, which is available to order, is developed to boost productivity in the whole drilling process.

The introduction of the Speedy bit comes a day after Sandvik released its new drilling tool system, the Alpha 360.
