The Sutton Tools Heavy Duty Cobalt jobber drills are designed for industrial quality performance, particularly in materials with high hardness and tensile strength such as cast iron, bronze, hardened steel, and stainless steel. These drill bits feature a split point at 135, which allows for accurate positioning and reduces drilling pressure, making them highly efficient for demanding tasks.

Constructed from HSS Co, the 5% cobalt formula enhances abrasive and heat resistance, providing increased strength at higher cutting temperatures. The thick core design ensures greater rigidity when working with hard materials. Additionally, the colour-tempered surface finish allows for easy identification of the cobalt tool material. The precision-engineered parallel shank guarantees accurate hole sizes, making these drills a reliable choice for professional applications.
