Magni Alfra core drill HSS 19/50mm

Core drill, bright HSS with a 19 mm Weldon shank and 2 drive flats. The inner diameter is 6.35 mm. The core drill only cuts a thin ring of material. The ejection of the remaining core is facilitated by a guide and a spring-loaded ejector pin. The quick removal of chips upwards minimizes the risk of breakage. It requires relatively little energy, even with large drilling diameters, and comes with a pre-cutter and post-cutter.
