The 135 split point (drills > 2mm & 3/32) enables accurate positioning and reduces drilling pressure. The thick core design enhances rigidity when working with hard materials. Made from HSS Co, the 5% cobalt formula significantly improves abrasive and heat resistance, ensuring increased strength at higher cutting temperatures. The color-tempered surface finish allows for easy identification of cobalt tool material.

Precision-engineered with a parallel shank, these drill bits ensure accurate hole sizes. Sutton Tools Heavy Duty Cobalt jobber drills are of industrial quality, ideal for drilling materials with high hardness and tensile strength, such as cast iron, bronze, hardened steel, and stainless steel. These drill bits feature a thick core for increased rigidity in hard materials, making them a reliable choice for demanding applications.
