Dynadrill DTH Hammer:

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.

» Designed to suit high pressure drilling rigs.

» Water well drilling

» Record breaking penetration.

» Bench drilling

» Exploring Civil Engineering Applications

» Lowest cost per foot drilled.

» Mining /Mineral Exploration

» Simple & robust design. Exploring Civil Engineering Applications

» Oil well drilling

» Foot Valve not required in the bit.

» Longer parts life.

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.

New design Hybrid Rotary Drill Bits (Tungsten Stud Bit) :

A new generation of Drill Bits for Soft-Medium rock formations making possible faster penetration and lower cost per Metre.

Bit Size in Inch	API pin Size in Inch
6 1/4	3 1/2 Reg.
7 5/8	4 1/2 Reg.
8 1/2	4 1/2 Reg.

New design Hybrid Rotary Drill Bits

Life Expectancy How They Outperform Tricone Rock Roller Bits

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

Shearing cutting action allows drilling with less weight on bit. Flush holes perform Nozzles function in Air Rotary Drilling

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.
