These engineer quality, left hand spiral drill bits are made from high quality M35 steel with 5% Cobalt for longer life.\n\nThey give a superior performance even when drilling challenging materials such as stainless steel and high alloy steel.\n\nWith a precision ground tip, split point and 135\u00B0 angle, these DIN 338 bits are very precise for centring during spot drilling.\n\nFor tough or hard metal drilling such as high tensile and hardened steels, including stainless steel (Cr-Ni) and purpose made acid resistant metals.\n\nIdeal for removing broken or damaged studs and fasteners.\n\nDrill a pilot hole in the dead centre of the fastener. Choose the correct left hand drill bit diameter for the task, then set the drill to reverse and a low speed.\n\n\u2022 Sizes: 1.5, 2.0, 2.5, 3.0, 3.2, 3.5, 4.0, 4.5, 4.8, 5.0, 5.5, 6.0 and 6.5mm\n\n\u2022 Left hand spiral\n\n\u2022 Engineering quality\n\n\u2022 Longer life\n\n\u2022 Superior performance with stainless steel\n\n\u2022 HSS M35, 5%r
