GUHRING 00534 018.250 DRILLS OTHER 9005340182500

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. Furthermore, the drill wall surface is improved so that a reamer can be subsequently used for perfect final reaming. 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 designs or VHM/HM assembly or long flute counter bores according to DIN 1864 available on request.
