Product Details
This kit includes large size general-purpose drills with a three-flatted 1/2" reduced shank, manufactured from high-speed steel substrate. The drills feature 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" to enhance rigidity, reduce deflection, and improve hole accuracy. The standardized lengths minimize adjustment during tool changes in screw machines and machining centers. The three flats on the shank provide a more secure grip in the drill chuck, reducing slippage under high loads, making these drills ideal for portable drilling operations due to their increased rigidity. The black and gold oxide finish enhances wear resistance and adds lubricity, facilitating better chip flow. These drills are suitable for use where maximum chuck capacity is 1/2" and can be used for drilling in carbon steel, alloy steel, cast iron, and wood. The product is made in the USA and comes with a 30-day warranty.
