Heavy Duty Bits

Heavy Duty Bits are a collection of top hammer drill bits for production drilling and quarrying. Longer grinding intervals and extended service life provide increased productivity and improved sustainability.

Features

Stronger design

Heavy Duty Bits have a fully covered front, as well as buttons at three angles to improve service life for gauge row. This product also features a large flushing capacity with improved ROP - all leading to more drill speed and increased productivity.
Innovative productivity

Heavy Duty Bits are made to last. Depending on rock conditions, you can expect up to twice the service life compared to standard bits, as well as lower cost per meter and ultimately lower total drilling cost.
Cost-effective technology

The longer service life means less manual handling, reduced risk of injury, lower cost and less manufacturing carbon footprint. PowerCarbide® selection includes gradient grades, GC81 and self-hardening grades SH70. It is a unique combination of strength, hardness, toughness and wear resistance.
