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 designed for easier and more precise penetration, with a standard overall length of 6" and a flute length of 3-1/8" to enhance rigidity, reduce deflection, and improve hole accuracy. The standardized lengths allow for minimal adjustments during tool changes in screw machines and machining centers. The three flats on the shank provide a more positive grip in the drill chuck, effectively 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 enhances wear resistance and adds lubricity, improving chip flow. Suitable for use wherever maximum chuck capacity is 1/2", these drills can be utilized for drilling in carbon steel, alloy steel, cast iron, and wood. They are made in the USA and come with a 30-day warranty.
