Drill King International hammers
DTH air hammer
A pneumatically operated valveless percussion drill, the DTH uses air to force a piston to strike the bit, producing high impact loads and penetration through very hard formations.
Heavy duty hammer
Tough construction and durability make the Drill King heavy duty hammer ideal for enhanced wear protection in hard, abrasive formations.
