DHD350-152 DTH Hammer Bit

1.Flat Face:An universal design, especially for hard and abrasive rock formation. Typically, flat face with hemispherical buttons design is the most popular choice. This kind of face shape is suitable for hard to very hard and abrasive rock formations in application with high air pressure. Good penetration rates an resistance to steel wash.

2.Dome/Hemispherical Buttons:Universal buttons for all rock formation, best suited to hardest and very abrasive rock formation.

3.Semi-Ballistic/Parabolic Buttons:Excellent penetration rate, but only suited to medium hard and not so very abrasive rock formation.

 

DHD shank DTH drill bit with flat face, 8 dome & 8 semi-ballistic carbide buttons for blasting bore holes, water well drilling.

DTH hammer bit with foot valve.

(1) Made from premium quality nickel-alloy steel 25SiMnCrNi2MoVA 
for increased durability and wear characteristics,  and YK 05 tungsten 
carbide as same grade as internationally well-known brand 
(2) Apply "hot (thermal) -insertion" processing procedure to 
insert the buttons as same as internationally well-known brand, 
(3) Entire CNC processing procedure ensure the quality consistency and reliable. 
(4) Military grade requirements of heat-treatment guarantee durability,
Specific heat treatment standards and special "stress relief" processes ensure 
consistent performance.
(5) Designed for maximum performance and hole cleaning ability and high penetration rate.
