Product Details
The large size general-purpose drills feature a three-flatted 1/2" reduced shank and are manufactured from high-speed steel substrate. Designed with a 118° split point, these drills ensure easier and more precise penetration. They have a standard overall length of 6" and a flute length of 3-1/8", which contributes to 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 provide a positive grip in the drill chuck, minimizing slippage under high loads, making them ideal for portable drilling applications. The black and gold (barber pole) oxide finish enhances wear resistance and adds lubricity, improving chip flow. These drills are suitable for use wherever maximum chuck capacity is 1/2", specifically for drilling in materials such as carbon steel, alloy steel, cast iron, and wood. These products are made in the USA and come with a 30-day warranty.
