Fein HSS Dura 25 12-60mm x 25mm Core Drill Bit 3/4in Weldon Holder

The Fein HSS Dura 25 core drill bit is designed for demanding drilling applications in steel and stainless steel. Its HSS construction provides high impact and shock resistance, while the titanium nitride (TiN) coating reduces friction and wear for efficient cutting and extended service life. Available in Ø 12–60 mm with a 25 mm cutting depth, it is suitable for steel up to 750 N/mm², stainless steel and aluminium, and can also be used for short-term dry drilling. Fein specifies a service life of up to 170 holes or 3.4 metres under optimum test conditions.
