DYNADRILL is manufacturing 6 sizes of Hammer and mating Button Bits

Dynadrill DTH Hammer

» DYNADRILL PRITHVI 30 for drilling 3 1/2" to 4" in hard rock and 5" to 6" in over burden drilling.
» DYNADRILL PRITHVI 40 for drilling 4.1/8" to 5" in hard rock and 6" to 7" in over burden drilling.
» DYNADRILL PRITHVI 60 / 65 for drilling 6" to 6.1/2" in hard rock and 8" to 9" in over burden drilling.
» DYNADRILL PRITHVI 80 for drilling 8" to 8.1/2" in hard rock and 10" to 12" in over burden drilling.
» DYNADRILL PRITHVI 100 for drilling 10" to 10.1/2" in hard rock and 12" to 14" in over burden drilling.
» DYNADRILL PRITHVI 120 for drilling 12" to 12.1/2" in hard rock and 13" to 17.1/2" in over burden drilling.

PRITHVI SERIES are 4th generation Hammers, we eliminated Foot Valve in the Button Bit which is the potential trouble maker when the drilling is in deep depth.

The Proprietory Dynadrill's "PRITHVI SERIES HAMMERS" Maximises efficiency and develops greater power for any compressor capacities available.As a result the Prithvi series of Hammers penetrate 15% to 30% faster than competative Hammers available in the market giving you an additional production at a lower unit cost.

Special Features :

» Computer analysis and laboratory trials have been used to optimize the number of buttons as well as their size and positioning throughout the bit front.
» Carbide has been carefully designed to minimize the risk of button loss and button failure
» The design of the bit body and the frontal sludge grooves provides uniform flushing with reduces steel wash on both bit and the hammer.
» Material processes and multiple heat treatment have focussed on achieving maximum resistance to fatigue failure.
» Special bit designs such as Concave and Convex/CB are available on request.

Overburden Tools :   

 

Dynadrill O-Dex systems for DTH hammers are designed to drill and case simultaneously through overburden, passing easily through large boulders, pulling lightweight, inexpensive casings behind them. On reaching the bedrock or required depth, the drillstring is removed easily from the hole, leaving the casings in place. Drilling into the bedrock can then be continued using a normal drill bit.

Life Expectancy How They Outperform Tricone Rock Roller Bits
Single piece bit body eliminates bit Stud cutter positioning on bit shanks ensure removal of equal volume of rock in each RPM
Single piece bit body eliminates bit failures, altogether. Stud cutter positioning on bit shanks ensure removal of equal volume of rock in each RPM.

How Hybrid Rotary Drill Bits Work

1. Rock Cutting By Shearing By Crushing
2. Bit Body Single Piece 3 Cones Welded Assembly
3. Movable Parts None Many, moving in two axial directions.
4. Drilling TC Stud Cutter Milled Tooth
5. Rock Yield Maximum Average
6. Cutter Position Capable to remove equal volume of rock. Unequal due to Cones Setup
7. Weight on Bit Less More

10. Round trips/bit changes Minimum. Maximum
11. Drill Collars Minimum. Maximum
12. Fishing Uncommon due to bit failure. Common due to bit failure
13. Bit designs Matched to formation types Limitation due to movable parts.
14. Bit/Failure during drilling Uncommon Common due to failure of cones, rollers, bearings, seals, nozzles, welds, etc.
15. Cost per metre of drilling Low High
16. Price Competitive by performance High

General Usage Characteristics :

» Hybrid bits drill by shearing of rock
» Stud cutters provide increased RPM, with less weight on bit.
» Types of bits are designed to IADC code to international standards.Bit styles can be matched to formation characters, Avail free guidance (from Manufacturers) to obtain optimum cost benefit, related to formation types intended to be drilled.
» Order bits indicating catalogue code number, and size in mm.
» Hybrid bits provide API standard bit tolerances ranging in +1/32" to 0.
» All the bits work with all makes of drilling rigs both for blast hole and water well drilling.
» usable for air/water/mud/direct rotary drilling.
