The Walter-Titex 7577886 is a high-precision solid carbide micro drill bit designed for drilling small-diameter holes in hard-to-machine materials. With a cutting diameter of 1.55 mm (0.061 inches) and a 140-degree point angle, this drill bit ensures accurate and efficient drilling operations. The AlCrN (Aluminum Chromium Nitride) coating enhances tool life and performance by providing increased hardness and wear resistance, making it suitable for demanding applications. The drill bit features a straight cylindrical shank with a diameter of 3 mm (0.118 inches) and an overall length of 60 mm (2.362 inches), allowing for versatility in various drilling setups. The two-flute design with a 30-degree helix angle facilitates efficient chip removal, reducing the risk of clogging and ensuring consistent hole quality. The coolant-through capability enables effective cooling and lubrication during drilling, further extending tool life and improving performance. This micro drill bit is ideal for applications requiring precise and reliable drilling in small diameters, such as in the electronics and medical device industries, where accuracy and surface finish are critical.
