Fein HSS Special 25 Core Bit with 3/4in Weldon Fitting
The FEIN HSS SPECIAL 25 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 industrial metalworking environments, this high-performance core bit delivers clean hole creation with reduced effort while ensuring long service life and dependable performance in demanding fabrication and structural 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 steel in a single operation without core removal, helping professionals achieve smoother results with minimal burr formation and reduced post-processing time. The robust construction also provides excellent resistance to impact and shock during heavy-duty use.
25 mm cutting depth and a standard 3/4 in Weldon fitting, this HSS SPECIAL 25 core bit ensures secure tool engagement and efficient power transfer. Designed for metal drilling applications including steel and aluminium, it is ideal for fabrication workshops, structural retrofitting, vehicle frame construction and repetitive industrial drilling tasks requiring precision and reliability.
