Description
PRODUCT OVERVIEW
This Magnum Super Premium 5/16″ drill bit outperforms cobalt drills in work hardening stainless steel and other tough drilling applications. The nitro-carburized flute has an increased Rockwell hardness. The flatter point takes a smaller chip. More torque is directed to a smaller area. This allows drilling into materials with hardness of over 30 on the Rockwell “C” scale. The split point design gives accurate starting without the use of a center punch. This bit has 135° point taking a smaller chip, resulting in less heat. Also sold in pack of 6 drill bits.
