SINTERED (METAL BOND) SUPER PREMIUM QUALITY – Pointed Segments
Designed for Drilling Hard Materials such as full range of Rocks (granite, marble, quartz, flagstone, sandstone, onyx, amethyst, travertine, garnet. Will also work (agate, jasper, jade, petrified wood, and similar minerals). What sets these core bits apart is high grade of diamond used & advanced bond formulation designed for Hard Material. The diamond segment is shaped in a U form, has double-pointed tips penetrate quickly and hold a straight drilling path to reduce side drag, and also increases coolant flow to reduce heat and removal slurry more efficiently. Diamond Segments are Laser Welded to precision machined steel body by automatic process that is very highly consistent and error free.
