Bernardo HSS core drill set 14 - 24 mm
Suitable for all core drills featuring a 19 mm Weldon chuck, as well as all stationary drilling machines featuring a quick release collar. Ensures for high convenience when drilling pipes, off-centre or overlapping drilling of oblong holes.
Core drills are often better suited than twist drills because of the small ring which is being drilled as opposed to the entire drill area, resulting in less need for force. Furthermore, there is no need for pre-drilling, the drill core gets ejected. These advantages bring a time saving of up to 40%.
