76mm 89mm 102mm 115mm hammer drill bits for rock

This type of bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 Mpa to 260 Mpa compressive strength). Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture. Recommended for eliminating hole deviation. Used in benching and long hole drilling.
