The 135° split point on these drills, which are greater than 2mm and 3/32 in size, ensures precise positioning and reduces the need for excessive drilling pressure. The thick core design enhances rigidity, making these drills ideal for use in hard materials. Crafted from high-speed steel with a 5% cobalt formula, these drills offer superior abrasive and heat resistance, providing increased strength at higher cutting temperatures.
The color-tempered surface finish allows for easy identification of the cobalt tool material. Precision-engineered with a parallel shank, these drills guarantee accurate hole sizes. Sutton Tools Heavy Duty Cobalt jobber drills are of industrial quality, specifically designed for drilling materials with high hardness and tensile strength, such as cast iron, bronze, hardened steel, and stainless steel.
