Large Diameter Hammers

The availability of large diameter hammers has opened up potential applications that were once only achievable with the use of very large, expensive rotary machines and penetration rates were relatively slow.

These same applications can now be undertaken with reasonably sized DTH drill rigs or alternatively, existing rotary machines can be easily converted to DTH drilling.

Penetration rates are now significantly increased and drilling costs considerably reduced.

Bulroc now offer large diameter hammers and the complete drill string for hole sizes ranging from 302mm (12”) through to 1090mm (43”)
