Impact drivers have become very popular in recent years, but unfortunately, their high torque can easily snap conventional bits. Makita's line of Impact Gold bits can deliver up to 10 times the life of standard bits (according to the manufacturer). They're stronger because they're flexible – Makita calls it "Xtreme Torsion Technology." which allows the bit to flex under load. The line includes insert bits, bit holders, double-ended power bits, nut setters, sockets and socket adapters.
