Description

DHD350 152mm Hole Hammer Drilling Dth Drill Bit

High pressure DHD350 hammer bit Description: In DTH drilling, drill rods and bits are the most important parts of the drilling process. When working, the drill rods transmit the necessary feed force and rotation to hammer and bit plus compressed air or fluids for the hammer and flushing of cuttings, the hammer is located between the drill rod and bit. As the hole gets deeper, the length of drill rod must be increased, so one and one drill rods are needed to increase the total length of the drill rods.

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.

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

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