Fein HSS NOVA 100 Core Bit with 3/4in Weldon Fitting
The FEIN HSS NOVA 100 Core Bit with 3/4 in Weldon Fitting is a professional-grade core drilling accessory designed for accurate, efficient and reliable deep-hole drilling in structural steel and demanding industrial applications. Engineered for use with magnetic drilling machines, this high-performance HSS core bit delivers clean, precise holes while minimising drilling effort and maximising productivity in fabrication, construction and engineering environments.
Manufactured from durable HSS (High-Speed Steel) with a hardness rating of 64 HRC, this core drill bit provides consistent cutting performance, excellent wear resistance and long service life under continuous use. Its extra-long design enables deeper drilling operations up to 100 mm cutting depth, while wide flute geometry ensures optimal chip evacuation to reduce jamming and improve drilling stability. The robust and impact-resistant construction makes it suitable for heavy-duty professional applications, especially in S235 structural steel.
With a diameter, extended 100 mm cutting depth and a standard 3/4 in Weldon fitting, this FEIN HSS NOVA 100 core bit ensures secure engagement, reliable torque transfer and precise hole alignment. Designed for situations where height differences between the magnetic drill and the workpiece must be compensated, it is an ideal solution for retrofit work, structural fabrication and industrial maintenance projects requiring deep and accurate core drilling.
