Product details : GUHRING 00534 025.000 CORE DRILLS
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.
Profile grinding, steam tempered surface, right cutting.
Normal angle of rake, normal core thickness and without core gradient.

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.
