Product Details
The large size general-purpose drills feature a three-flatted 1/2" reduced shank and are manufactured from high-speed steel substrate, ensuring durability and efficiency. These drills 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" that provides 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 offer a more positive grip in the drill chuck, effectively reducing drill slippage under high loads. This design is ideal for portable drilling applications due to enhanced rigidity. The black and gold (barber pole) oxide finish enhances wear resistance and adds lubricity, promoting better chip flow. These drills are suitable 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, the product comes with a 30-day warranty.
