For screws to ISO 2009, 2010, 7047 (DIN 963, 964, 966). Suitable for holes with simultaneous countersinking in profile material. HSS-XE steel Made of high-alloyed specialty steel 'XE' for considerably longer tool life than HSS-steel. For countersinking in materials: • High-alloyed chromium steel such as stainless (V2A – AISI 304) • Steel • Cast iron • Non-ferrous metals Use: The hole and countersink are produced in one operation and are precisely aligned making for sturdy and tight concentricity tolerances. Suitable for NC machines due to the high positional accuracy, excellent centering properties, and great sturdiness of the drill. The preceding centering operation can often be omitted. Designed for thread tapping drill holes to DIN 336 sheet 1 with 90° countersink. In the following operation, the tap does not have to cut into the sharp edge of the hole. Through hole with counterbore for screw head drilled in one operation. 1441 Cutting data Movie Art.
