How to Select DTH Bits Face shape and Carbide Button Shape

 

A:Bits face shape selection

 

Drop Center

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

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:

  • High Nickel-alloy steel or Molybdenum-alloy steel for increasing durability and wear characteristics.
  • Specific heat treatment standards and strict production process enssure consistent performance.
  • Simple structure for easy use and maintenance
  • Fast drilling speed, no need grinding.
