The Sutton Tools Heavy Duty Cobalt jobber drills are designed for precision and durability, making them ideal for industrial applications. The split point (drills > 2mm & 3/32) enables accurate positioning and reduces drilling pressure, ensuring a smooth and efficient drilling process. The thick core enhances rigidity, especially when working with hard materials, providing stability and reducing the risk of breakage.

Constructed from HSS Co., these drill bits feature a 5% cobalt formula that significantly improves abrasive and heat resistance, allowing for increased strength at higher cutting temperatures. The color-tempered surface finish not only aids in the identification of cobalt tool material but also adds an extra layer of durability. The precision-engineered parallel shank ensures accurate hole sizes, making these drills a reliable choice for materials with high hardness and tensile strength, such as cast iron, bronze, hardened steel, and stainless steel.
