Hao Carbide cemented carbide buttons for mining are designed to promote drilling efficiency that have a direct impact on rates of penetration in a variety of rock formations.
Ballistic and Conical Cemented Carbide Buttons for Mining
Ballistic and conical buttons are used in medium-hard to hard formation rotary drill and percussion bits. They can be customer specific or standard geometries where tooling exists.
Chisel Cemented Carbide Buttons for Mining
Our product range covers customer specials and standard geometries where existing tools can be utilized. The chisel geometry, in conjunction with grade technology, will improve the strength and minimize breakage.
Flat and Semi-round Top Geometry Cemented Carbide Buttons for Mining
Flat and semi-round top geometry buttons are used to reduce wear adjacent to the Gage on the legs and cones of rotary drill bits. Shapes can be manufactured to customer specifications or in a standard option where tooling is available.
Hemispheric Cemented Carbide Buttons for Mining
Hemispherical buttons can be a full radius used in formations of medium to medium-hard formation rotary drill and percussion bits. They can also be manufactured with a larger nose radius, which are used where extra strength is required.
Sculptured Cemented Carbide Buttons for Mining
Hao Carbide design and manufacturing capabilities can meet the requirements of complex, customized geometries and the dynamic demands put on buttons used in rock tools where high penetration rates are required in different rock formations.
Serrated Cemented Carbide Buttons for Mining
Similar to the flat geometry buttons, serrated buttons are used to prevent wear on the steel surfaces such as the legs and cones of rotary drill bits. The advantage of using this type of button is that the location pocket does not need precision drilling and provides better grip for buttons. Serrated buttons are an economical option.
Wedge Crested Cemented Carbide Buttons for Mining
This type of button is predominantly used in the outer or Gage row on rotary drill bits. The wedge design increases button strength.
