The Walter Surface Technologies 7684255 Extra Long Drill Bit is engineered for precision drilling in applications requiring extended reach and depth. With an overall length of 175.00 mm and a cutting diameter of 6.35 mm, this drill bit is designed to access hard-to-reach areas while maintaining drilling accuracy. The TiSiAlCrN/AlTiN coating enhances tool life and performance, making it suitable for drilling into a variety of materials, including aluminum, brass, bronze, cast iron, copper, steel, super-alloys, and titanium. The right-hand cutting direction and 140, point angle facilitate efficient chip removal and smooth drilling operations. Equipped with two flutes and two coolant holes, the drill bit ensures effective chip evacuation and cooling, reducing the risk of tool wear and improving overall drilling efficiency. The straight shank with H6 tolerance provides a secure fit in standard chucks, while the 16xD depth-to-diameter ratio allows for deeper drilling without compromising stability. Weighing 0.023 kg, this drill bit offers a balance between strength and maneuverability, making it an essential tool for precision drilling tasks in various industrial applications.
