Drilling and countersink tools HSS conical countersinks HSSE DIN 335 C 90° conical countersinks, Co5 type

Technical information

Description

High-performance countersink tools with a countersink angle of 90° for countersinking 90° screws for particularly tough and hard materials such as alloyed and high-strength steel and stainless steel (INOX). To ensure reliable torque transmission, conical countersinks have a three-surface shaft from a countersink diameter of 28 mm. Long tool life and temperatureresistant type due to Co content.
