Core drill with Morse taper shank Design: HSS, DIN 343, type N. Profile grinding, steam tempered surface, right cutting. Normal angle of rake, normal core thickness and without core gradient. Application: For drilling out pre-drilled, pre-cast or pre-punched holes. The sturdy construction and 3 blades means that alignment inaccuracies and runouts in pre-drilled holes are corrected. In addition, the drill wall surface is so far improved that can then be thoroughly finished with a reamer. Please pay attention to the column smallest Ø of pre-drilled hole. Note: The cut diameter must be smaller than the hole to be drilled out. Further dimensions or HSS-E versions or solid carbide/carbide components or long core drills according to DIN 1864 available on request.
