DTH Drill Bits
Down-The-Hole percussion drill bits for hard rock mining applications.
Down-The-Hole Drilling
DTH (Down-The-Hole) drilling places the hammer directly behind the bit at the bottom of the hole, delivering maximum impact energy to the rock face. This method is ideal for hard rock conditions where rotary drilling cannot achieve the required penetration rates.
Our DTH bits are manufactured with precision-machined button pockets and fitted with quality tungsten carbide buttons in-house. This ensures consistent button retention and optimal drilling performance.
Mining Applications
DTH bits for surface and underground hard rock drilling.
Gold Mining
Deep level and surface gold operations in hard, abrasive rock formations.
Platinum Mining
Bushveld Complex operations requiring consistent penetration in varying rock types.
Hard Rock
General hard rock drilling where high impact energy is required for penetration.
Blast Hole Drilling
Production blast hole drilling for surface and underground operations.
