Hammer Equipment

The Percussion Drilling technique involves a drill bit attached to a rope or cable which is repeatedly raised and lowered, impacting soil and rock, and making a hole deeper.  The fractured or broken up rock are then removed by using a valve for cleaning.

Its scope is focused in areas from medium hardness to low or those that are extremely fragile.

The striking frequency is around 40 to 50 strokes/minute, depending on the mechanical parameters of the drilled ground. With this, performance of 2 to 4 metres per day of hard materials and 10 to 20 metres per day in soft materials are achieved. Percussion is made directly on bore hole and its activation is made pneumatically. Causing a very efficient transmission of energy.

Hammers provided by TDS delivers more force to the down hole tools because air flow technology have been widely developed, so your operations time will be decreased.  All of TDS DTH hammers come with adjustable chokes affecting the performance of down hole tools. Another drilling supply that TDS has helped to develop is a blow back sub which can be mounted above the down hole hammer.
