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 TITAN- TEC coated TITAN- TEC coated KARNASCH NORM PROPERTIES HSS-XE steel + TITAN-TEC coated Made of high-alloyed special steel 'XE' for considerably longer service life than HSS-steel. TITAN-TEC coating for a further substantial increase in service life also when machining dry (no/less cooling) For countersinking in materials: • High-alloyed chromium steel such as stainless (V2A / V4A) • Acid resistant steel • Steel • Cast iron • Non ferrous metals Alu Steel Stainless Copper, brass, tin Plastics GRP/CRP Grey cast iron HSS-XE + TITAN-TEC stub subland drill with long drilling step for through holes 90° HSS-XE + TITAN-TEC stub jobber drills for tapping holes, 90° countersink Through hole with counterbore for screw head drilled in one operation.
