The drill anything drills hardened tips shatter when drilling steel on first use happened twice.l called the company to get my money back and was transferred 4 times put on hold for long periods eventually got offered replacement drill bits if l sent photos of broken ones. They refused to give money back booked a return call within 48 hours that never happened. The drills in the adds are obviously diamond tipped to chew through a grinding stone like they demonstrate. Clearly false advertising. These products are from the land of cheats, i.e. under arm bowling, ball tempering (sanding) knee drops on Richie's head, eye gouging etc. There is no need to cheat. The TV shop needs to be shut down.
