Stanley 1mm-5.5mm Din 338 High Speed Steel Metal Twist Drill Bits in Bulk

Stanley 1mm-5.5mm Din 338 High Speed Steel Metal Twist Drill Bits in Bulk About this productThe Stanley High Speed Steel (HSS-G) Metal Twist Drill Bits are precision-ground accessories designed for fast, accurate drilling through various types of metals. Manufactured according to the standard DIN 338 dimensions, they are compatible with both corded/cordless drills and stationary drill stands. Design and Features:HSS-G (Ground Steel) Construction: These bits are precision-ground from solid high-speed steel. This manufacturing process ensures excellent concentricity, precise cutting edges, and a longer tool life compared to standard roll-forged HSS bits.DIN 338 Standard: They conform to the industry-standard DIN 338 specifications, ensuring consistent dimensions, flute lengths, and overall quality control.Split Point Tip: They typically feature a 135-degree split point design. This allows for self-centering action, preventing the drill bit from walking or wandering across the metal surface when you start drilling. Optimized Flute Design: The ground flutes ensure rapid and efficient chip removal, which reduces heat buildup and prevents the bit from binding or jamming during heavy use. Versatile Material Compatibility:They are specifically engineered to drill through tough materials, including:-Alloyed and unalloyed steel Cast iron and cast steel-Non-ferrous metals (like aluminum, brass, and copper)-Sintered iron-Hard plastics
