Product Details
The large size general-purpose drills feature a three-flatted 1/2" reduced shank and are manufactured from premium cobalt high-speed steel. They have a 118° split point designed for easier, more precise penetration and a standard overall length of 6" with a flute length of 3-1/8", which increases rigidity, reduces deflection, and improves 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 more positive grip in the drill chuck, reducing slippage under high loads, making them ideal for portable drilling due to their increased rigidity. The TiN (Titanium Nitride) coating enhances lubricity, hardness, chip flow, finish hole quality, and overall drill life. These drills are suitable for use wherever the maximum chuck capacity is 1/2" and are effective for drilling in carbon steel, alloy steel, and cast iron. Made in the USA, they come with a 30-day warranty.
