High-quality
forgings are sourced from the UK for the bits. The heat-treatment process
ensures a
hard, tough and fatigue-resistant product of high performance.
Spes
excels in designing and developing bits for the most arduous conditions
and collaborates closely with suppliers and users to achieve this.
Powder
Industries, a South African manufacturer of tungsten-carbide buttons, for
example, has developed particular grades and button geometries to
successfully meet the challenges.
The bits are
widely used in applications such as drop-raise drilling in solid quartzites in the South African deep-level gold mines, blastholes in
banded ironstones and iron ore and waterwells in aggressive sandstones.
Spes
has innovative bit designs such as bits with side-flushing and two-piece
hole-openers with replaceable drill
heads.
