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.
Crafted from HSS Co., the 5% cobalt formula significantly improves abrasive and heat resistance, allowing the drill bits to maintain their 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 drill bits a reliable choice for drilling materials with high hardness and tensile strength, such as cast iron, bronze, hardened steel, and stainless steel.
