Product Introduce
DTH hammer is a percussion system driving a piston inside hammer
body with up and donw motion by compressed air and transmitting an
intensive percussion energy to the bit to enable the drilling by
crushing the rock. Drilling method by DTH hammer exerts high
drilling performance especially for drilling hard rock and
contributes for shortening work schedule. Hence, this method is
widely utilized for foundation work, landslide prevention work,
quarrying services, marine civil work, etc.
Our hammer and bits are made of high quality alloy steel with
advanced heat treatment to assure the good drilling performance and
long service life. They are widely used by our customers all over
the world.
All the products are manufactured as per the international
standard.
