Ruko Twist Drill Type UNI HSSE Co 5

6.0 x 93 x 57 mm. This high-performance spiral drill bit has been specifically designed for portable use in drills and cordless screwdrivers (optimal performance for materials up to 5.0 mm thick). The three-flat shank ensures excellent grip in the chuck with minimal effort. Additionally, the shank provides optimal power transfer, preventing the drill bit from slipping. The 135º high-performance cutting edge ensures very high centering accuracy, especially in hand-held applications with cordless screwdrivers. The cutting edge prevents slipping when drilling into curved surfaces. The battery life is extended by reducing cutting forces. The black chamfer increases wear resistance and prevents cold welding and buildup of cutting edges. The 40º spiral angle allows for perfect and rapid chip removal, ensuring high cutting speeds with increased stability and accuracy. HSS Co 5: High-performance high-speed steel with a 5% cobalt content. High toughness and heat resistance, suitable for drilling in difficult-to-machine materials with a strength of up to 1100 N/mm².
