Applications

Drilling works for blasting duties in tunneling, construction, mining, quarrying, etc.

Flat front: For drilling in medium to hard and abrasive rock

Drop center: For drilling in medium hard, with maximum hole deviation control.

Normal skirt: For drilling in very hard and very abrasive compact rock formation.

Retract skirt: For drilling in loose, broken or fissured rock where it is difficult to retract the drill string due to the hole collapse.
