rock mining tools
Down the hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powderto a down-the-hole bit to crush rocks.
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.
Widely used in mines, quarries, earthworks and other engineering drilling blasting hole, guardrail hole, mountain reinforcement, anchorage and other engineering holes, geothermal exploration hole, Well bore and other fields.
