RS is rock drilling tools manufacturer, we produce a various range of DTH hammer bits with DHD shanks type for a wide range of hole sizes, which have been designed to match all conceivable applications for water well industries, mining and construction

Flat Face
An universal design, especially for hard and abrasive rock formation. Typically, flat face with hemispherical buttons design is the most popular choice. This kind of face shape is suitable for hard to very hard and abrasive rock formations in application with high air pressure. Good penetration rates an resistance to steel wash.

Dome/Hemispherical Buttons
Universal buttons for all rock formation, best suited to hardest and very abrasive rock formation.

Semi-Ballistic/Parabolic Buttons
Excellent penetration rate, but only suited to medium hard and not so very abrasive rock formation.
RS DTH Bit features

1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to inner structure of HD series DTH hammer designed according to newest rock drilling theory.

2.Smooth performance and long service life of DTH bits due to high quality alloy steel materials and advanced processing technology adapted.

3.Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of DTH bits.

4.Easy to depart bit from hammer due to multi-head thread connection chuck and cylinder of hammer.

5. Can connect well with DTH bit and dill pipe manufactured by Atlas Copco and Sandvik.

We can also provide related products DTH hammers, ODEX system, symmetrix systems, slide block drilling systems, etc and DTH drilling pipes for various thread API REG, API IF, BECO, etc
