Propower Products offers a comprehensive range of quality DTH bits from the industry’s leading manufacturers
for use in all rock types and drilling conditions. Bit life and rate of penetration are the most important criteria in
selecting the right bit for a particular application.
DTH bits are available in sizes from 2" to 12". Bits come in three different standard bit head/face designs (Convex, Flat Face, and Concave), and with a number of tungsten carbide insert options, to guarantee a DTH drill bit that can tackle any challenge and rock-face formation. Additional bit head designs and custom options are available depending upon manufacturer.
Propower produce a wide range of button bits to suit all types and sizes of all popular makes of DTH hammers.
These are available in a variety of head forms and button shapes that are designed to give the driller the opportunity of choosing the best bit to efficiently drill all types different rocks and ground conditions.
All Propower bits in the intermediate range are produced from a high nickel alloy steel, heat treated to produce a surface resistant to fatigue and wear.
DTH (Down to Hole) drill bit, also called spline connected drill bit, is mainly used in large scale mine (open and underground), open quarry and construction. The hammer is situated down the hole in direct connected with the drill bit with splines in the bit. The hammer piston strikes the drill bit resulting in an efficient transmission of the impact energy and insignificant power losses with the hole depth.
How to Select DTH Bits Face shape and Carbide Button Shape
A:Bits face shape selection
Drop Center Bit
For high penetration rates in soft to medium-hard and fissured rock formations.
Concave Face
The all-round application bit face specifically for medium hard and homogeneous rock formation. Good hole deviation control and good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistance to steel wash, and good resistance to steel wash step gauge bit.
Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
B:Insert Carbide Button shape Selection
Different button is ideal for different ground conditions, abrasive levels, PSIs and penetration levels. In general, the more of gauge buttons, the better over performance, especially in hard rock.
Spherical
Ballistic Button
Semi-ballistic
Wedged (Conical) Button
Features of Nickel-alloy steel drill bits:
1) Reliability
The piston of DTH Hammer uses the special (imported) high nickel alloy steel, with advanced heat treatment as military industry standard.
Strengthening processing on hammer surface for higher were-resistance.
2)Suitability
Specially designed drill bits for middle soft and hard rock formations. Easily disassembly thread for easy maintenance.
3) Efficiency
Extra-short structure design DTH hammer and bit for great efficiency of high impact energy transmission, with high impact power and fast drilling rate.
Hammer and bit design are optimized by computer simulation, with best air distribution chamber and air tightness design.
Our DTH bits are widely used for produce large-diameter holes in rocks for water-well drilling, tunnels, mineral exploration, geothermal drilling, subway engineering drilling. quarrying and roads, power stations, and other construction projects. it is suitable for very hard and abrasive rock formation, medium-hard and homogeneous formation. soft rock and fissured rock formations etc.
Our factory also can supply you with high pressure and medium to low pressure DTH hammers. It strictly matches with API standard and other Chinese industry standards. It is durable for being produced with advanced craftwork and good material.
