With the Phantom din 172-A drill bush, you achieve precise and repeatable drilling across all your jigs and fixtures. This short series bushing, featuring a 10.2 mm inside diameter and a 12 mm length, guides your drill bit smoothly while preventing tool wandering, deflection, and vibration. Fully through-hardened and precision-ground inside and out with an F7 bore tolerance and n6 outer tolerance, it protects reusable drilling templates from mechanical wear during repetitive production runs. The integrated collar acts as a sturdy stop to prevent the bushing from pushing through under axial load, ensuring accurate pilot holes for M12 threads every time.
