Product Details
Large size general-purpose drills feature a three-flatted 1/2" reduced shank and are manufactured from high-speed steel substrate. They are designed with a 118° split point for easier, more precise penetration. With a standard overall length of 6" and a flute length of 3-1/8", these drills provide increased rigidity, less deflection, and better hole accuracy. The standardized lengths minimize adjustment during tool changes in screw machines and machining centers. The three flats on the shank offer a more positive grip in the drill chuck, reducing slippage under high loads, making them ideal for portable drilling due to the enhanced rigidity. The black and gold (barber pole) oxide finish increases wear resistance and adds lubricity, improving chip flow. These drills are suitable for use wherever the maximum chuck capacity is 1/2" and are effective for drilling in carbon steel, alloy steel, cast iron, and wood. They are made in the USA and come with a 30-day warranty.
