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