Fein HSS Special 50 Core Bit with 3/4in Weldon Fitting
The FEIN HSS SPECIAL 50 Core Bit with 3/4 in Weldon Fitting is a professional-grade core drilling accessory engineered for fast, precise and efficient metal drilling applications. Designed for magnetic drilling machines and demanding industrial environments, this high-performance core bit delivers clean, accurate hole cutting while reducing drilling effort and ensuring long service life in fabrication, structural steel and engineering applications.
Manufactured from high-strength HSS (High-Speed Steel) with a hardness rating of 64 HRC, this core bit is built for durability and consistent cutting performance. Its specialised cutting geometry enables drilling through multilayered stacked steel in a single operation without core removal, producing smooth holes with minimal burr formation and reducing secondary finishing work. The robust construction is impact and shock resistant, making it suitable for heavy-duty professional use.
With a diameter, 50 mm cutting depth and a standard 3/4 in Weldon fitting, this HSS SPECIAL 50 core bit ensures secure tool engagement and efficient torque transfer. Designed for structural retrofitting, vehicle frame construction and precision metal fabrication, it offers reliable performance where productivity, accuracy and durability are essential.
