what the DTH Bits Use

In order to properly use the drill hole, drill drilling speed and guarantee period of use, the following points should be noted:
1, according to the rock condition (hardness, abrasion resistance) and rig type (high pressure, low pressure) to select the drill hole. Different forms of alloy teeth and tooth arrangement method is applicable to different rock drilling. Choosing the ceramic tile saw  right drill hole, is a prerequisite to obtain the best results;
2, the installation DTH drill bit to drill gently into DTH hammer drill kit card, do not force the collision, to avoid damage to the caudal peduncle or card drill bit sets;
3, in the drilling process, to ensure that the pressure submersible drilling rig air pressure is sufficient. If there impactor intermittent work, or poor borehole ranked powder should be checked submersible drilling rig compressed air system to ensure no rocks hole drilling process slag;
4, if found metal objects fall into the table saw blades  hole in the magnet should be promptly sucked out or removed by other means, so as to avoid damage to the drill bit;
5, replace the drill bit to the attention of the blast hole drilling good size. If excessive wear of the drill diameter, but not yet drilled hole when the gun can not be replaced with new drill to avoid sticking. May have been used and worn with a diameter substantially the same as the old drill complete the job;
6, for the emergence of early non-normal retirement DTH drill bit, shall promptly notify the company to notify the  dry cut blades contents include:
1), rock type and construction sites;
2), supporting the use of the impactor model;
3), drill failure modes (broken teeth, lost teeth, drill head collapse block, drill caudal fracture);
4), bit life (number of meters have been drilled footage);
5), the number of failures drill;
6), the normal use of a few meters drill footage
