Drill Hammer Shank SD8 With Thread 4 1/2'' Api Reg For Down The
Hole Drilling
Product description
SOLLROC company makes and supplies the finest and most
efficient Down-the-Hole (DTH) hammers and bits for the mining,
construction and water well industries. Sollroc DTH hammers
transmit intensive impact energy with low energy loss. This results
in good rock breakage, high penetration rates and high
productivity. The equipment is designed to give optimal hole
quality, reliability, and long service life, as well as the best
blasting results and low total operation cost.
Advantages:
1. Advanced hammer designs with high power and air efficiency
increases productivity
2. Tailored product offering covers all your applications and
conditions
3. Easy service and maintenance designs reduces machine downtime
4. Generic and proprietary shank options give you flexibility and
reliability

Face shape Features
Drop Center
For high penetration rates in soft to medium hard and fissured rock
formations. Low to medium air pressures. Maximum hole deviation
control.
Concave Face
The all-round application bit face special for medium hard and
homogenerous rock formations. Good hole deviation control and good
flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to
medium air pressures. It is the most resistance to steel wash, and
may reduce the load and wear on the gauge buttons, but poor hole
deviation control.
Flat Face
This kind of face shape is suitable for very hard and abrasive rock
formations in applications with high air pressures. Good
penetration rates an resistance to steel wash.
Double Gauge Face
This kind of face shape is suitable for fast penetration rates in
medium to hard rock formations. Designed for high air pressures and
good resistance to steel wash step gauge bit.
Product application
At present, DTH drilling tool is widely used in underground mining,
quarries, hydraulic and Hydro-Power Engineering, water well
drilling, Mineral exploration, anchoring hole drilling, geothermal
engineering, Subway excavation, another civil engineering.
DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
