Description

Description

Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.

A, using the raw material of super coarse grain hard alloy, the alloy has been sintered under pressure to improve the hardness and toughness of the bit.


B, unique design, improve drilling speed, use significantly improve life.


C, select advanced steel to ensure that the overall performance of the bit is consistent.


D, after sale guarantee, to replace the bad goods package.
