ProMAXX's SSSC Gold, Platinum and Platinum Plus drill bit line is designed to cut through hard materials, including stainless steel, boron, ultra-high-strength steel, titanium and hardened steel. The drill bits are engine turned to close tolerances for precision and challenging applications such as those found in exhaust manifold repairs, body and machine shops. The drill bits are micro-edged to prevent walking, thin webbed and have high-degree primary and secondary relief cutting edges for speed, accuracy and temperature control.
