1. Hybrid bits drill by shearing of rock 2. Stud cutters provide increased RPM, with less weight on bit. 3. Types of bits are designed to IADC code to international standards. Bit styles can be matched to formation characters, Avail free guidance (from Manufacturers) to obtain optimum cost-benefit, related to formation types intended to be drilled. 4. Order bits indicating catalogue code number, and size in mm. 5. Hybrid bits provide API standard bit tolerances ranging from +1/32" to 0. 6. All the bits work with all makes of drilling rigs both for blast hole and water well drilling. 7. Usable for air/water/mud/direct rotary drilling.
