Quality: The S2 material from which the set is made gives it greater resistance to rust and corrosion. Serrations on the puller help remove difficult bolts.
Powerful accessories: It has a bit extension bracket (6.35mm, 1/4”) and socket adapter (4mm, 5/32”) of the screw removal set that fits most electric drills. Magnetism inside the base and adapter prevents pieces and screws from falling out.
