Special spherical profile diamond cutter, preventing chips and designed for hard rock drilling more.
Mounting the diamond layer to the cemented carbide substrate "herringbone", excluding chipping.
Chisel successfully used small-sized drilling rigs etc. When drilling: soft, dense, low abrasive rocks, quartz sandstone, limestone, dolomite, as well as the very hard rocks and granites. The body has a bit superficial hardening. Material cutters - polycrystalline diamond cutters make it possible to increase the wear resistance index and increase the drilling speed in comparison with a chisel equipped carbide. The ends of the bit segments are built for durability. The chisel has no moving parts, which can effectively destroy the rock at a minimum axial load and high speed, has a wide range of operating characteristics, more universal in application.
Modern diamond PDC bits have a higher speed, durability and efficiency of drilling wells compared to the carbide blade and roller cone bits, thereby increasing the performance of works by reducing the time and cost, and most importantly increase your profits!
