For screws to ISO 2009, 2010, 7047 (DIN 963, 964, 966). Especially suitable for holes with simultaneous countersinking in profile material. Use: Hole and countersink are produced in one operation and precise- ly aligned. Therefore very sturdy and tight concentricity tolerances. Particulary suitable for NC machines due to high positional accuracy, excellent centering properties and great sturdiness. The preceding cen- tering operation can thus often be omitted. For thread tapping drill holes to DIN 336 sheet 1 with 90° countersink. In the following operation, the tap therefore does not have to cut into the sharp edge of the hole APPLICATION KARNASCH NORM HSS-XE stub jobber drills for tapping holes, 90° countersink PROPERTIES HSS-XE steel Made of high-alloyed special steel 'XE' for considerably longer service life than HSS-steel. For countersinking in materials: • High-alloyed chromium steel such as stainless (V2A) • Steel • Cast iron • Non ferrous metals Through hole with counterbore for screw head drilled in one operation.
