The precision ground High Speed Steel (HSS) drill bit allows up to 40% faster drilling and up to 50% less pressure than standard ground HSS chisel bits. The drill is designed for drilling holes in alloy and non-alloy steel up to a tensile strength of 900 N/mm², ...in steel, lithium, sintered iron, malleable cast iron, non-ferrous metals and hard plastic. The HSS spiral drill bit is manufactured according to DIN 340. It is an N-type drill bit with a tip angle of 135 degrees and a diameter deviation of h8. It has a U-shape, two blades and a cylindrical shank with CYL clamping system (shank diameter corresponds to the drill bit diameter).
