Fein 33901680420 Structural Steel Core Drill Bit Set 3/4in Weldon / HSS NOVA 25mm

The FEIN Structural Steel Core Drill Bit Set 3/4 in Weldon / HSS NOVA 25 suer set of HSS core drill bits in an L-BOXX is a professional-grade core drilling kit engineered for steel construction, bridge fabrication and demanding installation work. Designed for use with magnetic drilling machines, this complete user set combines high-performance HSS core drill bits and essential accessories in one organised solution, helping professionals achieve fast, accurate and reliable drilling performance in structural steel environments.

This set includes the most common HSS core drill diameters, making it ideal for repetitive drilling tasks in fabrication and construction. The HSS NOVA 25 core drill bits are designed for long service life and high resistance to shock and impact, thanks to tough cutting edges and premium HSS steel with a hardness of 64 HRC. This makes the set especially suitable for rough on-site conditions, steel erection and bridge construction where durability and consistent cutting performance are essential.

Supplied in a practical L-BOXX 136 storage system, the set keeps all accessories organised, protected and ready for transport between workshop and jobsite. With included HSS twist drills, centring pins and cutting paste, this FEIN structural steel set provides everything required for core drilling and blind-hole preparation, while the standard 3/4 in Weldon interface ensures secure mounting and stable torque transfer across compatible magnetic drilling machines.
