Drill bits bearing the acronym HSS (high-speed steel) are extremely durable and designed especially for drilling into metal surfaces and so are very well suited to drilling into metal. Drill a deep hole through metal with maximum precision using long HSS twist drill bits with ground ends. As a result of the long bit’s length, it can drill deep into the ground. An active cut with a self-centering split-point tip with a 135-degree arc combines dynamic cutting and perfect centering. Its cylindrical shank is compatible with drill chucks equipped with three jaws. The HSS Twist Drill Bit offers solid drilling for a wide range of materials for standard metal drilling. An HSS-ground bit for precision grinding enables results to be obtained in a short amount of time. Until a diameter of 10 mm is reached, no pre-punching or pilot drilling is necessary. Type N drill bit with a 135-degree tip manufactured with a tolerance of 8 mm on the diameter. Many materials can be used for this bit, from cast steel to cast iron, iron sinter, sintered iron to malleable aluminum, and steel alloys. It can also drill deep holes in hard plastics and non-ferrous metals. As a result, they have been designed to be used with drill stands and drill drivers, and the shank system appears to be cylindrical (shank diameter equal to drill bit diameter). This powerful straight shank, right-hand cutting twist drill has a high drilling capacity and can drill diameters up to ten times the diameter of the drill before the flute has to be cleared.
