The ER25 collet chuck for magnetic drilling machines is a unique development among tool holders to drill, tap and countersink
Whereas the construction of a magnetic drilling machine in combination with a drill chuck and cylindrical drills often becomes too long, the Phantom ER25 collet chuck for smaller diameters with ER25 collets (up to 20 mm) makes the combination much shorter. This increases the space between the tool and the surface of the material (discharge). Any tool with a cylindrical shank up to 20 mm can be clamped in your magnetic drilling machine.
