Product Details
The large size general-purpose drills feature a three-flatted 1/2" reduced shank and are manufactured from high-speed steel substrate. With a 118° split point, these drills provide easier and more precise penetration. They have a standard overall length of 6" and a flute length of 3-1/8", which enhance rigidity, minimize deflection, and improve hole accuracy. The standardized lengths allow for minimal 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 drill slippage under high loads, making them ideal for portable drilling due to their increased 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 they can effectively drill through carbon steel, alloy steel, cast iron, and wood. Made in the USA, these drills come with a 30-day warranty.
