Introduction
2. Application: Special designed for mine drilling.
3. Cutting structure:Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new formula and new techniques of insert bit. Unique widened crest insert improved the bit aggressivity and penetration rate.
4. Gauge protection structure:The multiple heel position with gauge trimmer on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection.
5. Bearing structure: Air-cooled rolling bearing and sealed bearing are adopted for customers to choose, so as to optimize the matching gap between tooth claw, tooth wheel and steel ball, and minimize the chance of tooth loss accidents underground.
