Taper button bit is used for hard or very hard rock formation. Excellent quality and durability and Specialized heat treat & stress relief,also Maximum performance and hole cleaning ability.Thread button drill bits are made by high quality alloy steel bar and tungsten carbides. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. Besides, we can design customized thread button drill bits according to different drilling application, and custom drill bits are applicable to drill soft rock, loose-medium rock and hard rock.

1).Made from steel and tungsten carbide as same grade as internationally well-known brand

2).Apply “hot-insertion” processing procedure to insert the buttons as same as internationally well-known brand

3).Recommended specification according to different rock formation improves design and drilling speed

4).CNC processing procedure ensures the manufacturing precision and quality consistency

5).Durability from the military grade requirements of heat-treatment

1. Tapered drill rod and Tapered drill bit. The tapered degree would be 6°, 7°, 11°, 12°;

2. DTH Bit and DTH Hammer suit for DHD, QL, M, BR series;

3. Thread Button Bit and drill rod suit for R22, R25, R28, R32, R38, T38, T45, T51 etc.;

4. Self-drilling anchor tools;

5. Parts like shank adaptors, coupling sleeve etc.

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

  • Application Strength-multipurpose
  • Best suited to soft abrasive
  • 25,000 to 45,000 PSI (170 to 300 MPa)
  • Abrasive to very abrasive

Ballistic Button

  • Application Strength- fast penetration
  • Best suited to soft ground
  • 10,000to 20,000 PSI(70 to 140 MPa)
  • Non abrasive ground

Semi-ballistic

  • Application Strength-fast penetration
  • Best suited to medium ground
  • 15,000 to 25,000 PSI(100 to 170 MPs)
  • Mildly abrasive ground

Wedged (Conical) Button

  • Application Strength- fast penetration
  • Suited for all non-abrasive ground types
  • Smaller contact area
  • Best suited for smaller diameter bits

Features of Nickel-alloy steel drill bits:

1) ReliabilityThe 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)SuitabilitySpecially designed drill bits for middle soft and hard rock formations. Easily disassembly thread for easy maintenance.

3) EfficiencyExtra-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.

Design Principles and Advantages of our Products:1. According to the newest rock drilling theory to design our DTH hammer for deliver maximum energy to drilling bit and ensure high drilling rate.2. High quality alloy steel materials and advanced processing technology ensure smooth operation ,reliability and longer service life.3. The simple structure of our DTH hammer ensure low problem rate and easy operation&maintenance.4. The drilling speed is 15%-30% higher than other brands.
