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 design for easier and more precise penetration, with a standard overall length of 6" and a flute length of 3-1/8", which enhances rigidity, reduces deflection, and improves hole accuracy. The standardized lengths help minimize adjustment during tool changes in screw machines and machining centers. The three flats on the shank provide a more positive grip in the drill chuck, reducing drill slippage under high loads, making them ideal for portable drilling applications due to the increased rigidity. The black and gold (barber pole) oxide finish increases wear resistance and adds lubricity, facilitating better chip flow. These drills are suitable for use wherever maximum chuck capacity is 1/2" and are effective for drilling in carbon steel, alloy steel, cast iron, and wood. They come with a 30-day warranty.
