The WALTER 6618424 0.512" 140° Solid Carbide Jobber Drill Bit with TiAlN Coating is engineered for precision drilling in a variety of materials, including cast iron, non-ferrous metals, steel, superalloys, and titanium. This drill bit features a 140° point angle, providing self-centering capabilities that enhance drilling accuracy and reduce the risk of wandering during operation. The solid carbide construction offers exceptional hardness and wear resistance, ensuring prolonged tool life and consistent performance. The TiAlN (Titanium Aluminum Nitride) coating further enhances durability by reducing friction and heat buildup, making it suitable for high-speed drilling applications. The spiral flute design facilitates efficient chip removal, minimizing the chances of clogging and maintaining optimal cutting conditions. With a whistle notch shank, the drill bit ensures a secure fit in the chuck, preventing slippage and ensuring stability during drilling. The overall length of 4.8819 inches and flute length of 2.5600 inches provide the necessary reach for various drilling depths, while the flute by diameter ratio of 5xD allows for deeper hole drilling without compromising performance. This drill bit is part of the DC150 series, known for its reliability and precision in demanding drilling tasks.
