DTH Hammers & Hammer Bits

A down-hole hammer is a percussion hammer drill. In this type of hammer the piston applying repeated percussive pressure is in direct contact with the bit. As the name implies, this hammer works "down the hole". The hammer and the bit are located at the end of the drill string. One of the main advantages of the DTH hammer is that the drilling rate is not affected very much by the length or depth of the hole. DTH Hammers are well suited for drilling into medium hard to hard rock. They are especially well suited for drilling into fractured rock. They are extensively used in mining, quarrying, civil engineering and water well drilling industries.

Rocksmith offers top quality DTH hammers and bits. Our products have been tried and tested in the harshest of rock conditions. Our bits utilize quality hardened steel alloy for the bit body and premium quality tungsten carbide button inserts. Our products are recognized for having exceptional durability resulting in a very loyal and satisfied clientele.

Rocksmith provides hammers and bits with most popular shanks. We also specialize in supplying spares for individual hammer components.

To help ease the selection process we have categorized our DTH hammers based on hammer dimensions and our bits based on shank designation, bit diameter, bit face configuration, and carbide design.

Rocksmith offers DTH bits having concave, flat face and convex bit face configuration.

Stainless Steel Casings

Rocksmith also offers stainless steel (SS 304) pipes which are used as water bore casings for larger diameters drill holes. Stainless steel as a material is very durable and sturdy. It has high collapses strength and offers high resistance to corrosion.

Water Well Screens

Rocksmith offers water well screens made from Stainless Steel SS 304. The screens are manufactured by wrapping a wire around longitudinal rods. The wire is welded to the rods by resistance welding producing a cage-shaped cylindrical configuration.

There are several advantages a water well screen offers. They are as follows:

• The water well screen is a key component for controlling the sand entering the water bore circuit.
• The slot design of the screen resists plugging and prevents sand from damaging the pumps. The slots in the water well screens are unique in shape. The inwardly widening shape from the very edge of the slot allows only two point contact with any grain outside it. If the grain size is even marginally smaller, it slips right through without facing any resistance and is then removed out of the well with the water. The larger grains however remain outside. This design feature makes these screens non clogging type
• While the slotted UPVC pipes have least open area 10%- 15 % the 'V' wire wound screen has highest possible open area (14 %-50 %) The high open area allows for water to enter the well freely resulting in minimal drawdown and less energy usage by pump
• The wire and rod construction offers required strength for specified well depth
• The unique water well screen design allows for lower entrance velocity of the water, reducing the encrustation rate
• As the screen is made from stainless steel it offers maximum corrosion resistance for water chemistry
• The right selection of slot size is made after below ground sand sample analysis. The slot size, diameter, and the length of the screen can be customized to suit the requirement of the well
