It is guaranteed to cooperate well with the tapered drill rod (the taper is the same, the depth of the drill rod inserted into the taper hole must be greater than 25mm, and the head of the drill rod should not be filled against the bottom of the drill head), otherwise the bit will be lost;
Note: It is best to use the drill head product as the same manufacturer as the tapered drill rod to ensure that the taper is consistent and has a good fit.
2. When drilling the hole, the rock drill should reduce the air volume and reduce the damage caused by the high stress on the cemented carbide sheet. When the bit is completely smashed into the rock, the normal air volume is used.
