The Universal drilling guide "MASTER" from Pichler Tools allows for safe drilling out of broken stud bolts with thread sizes M6-M10. The set includes HARDOX-Drills with optimized cutting edges at 135-degree flat spiral angles and feature special coatings, making them suitable for tough materials. The kit also comes with a carbide head-cutter, ideal for levelling and smoothing the messy break-off edges of stripped screws. The drills measure 3 mm by 4.5 mm by 6.4 mm.
