Shattering bits.
Bought the Irwin XMS17 Impact driver bit set to go with by new Bosch 12v impact driver. This is a small lightweight driver, not a big heavy machine. Very disappointed to find the pozidrive bits shattering with very little use. I was laying a plywood floor, and had pre-drilled the plywood, so was only driving into softwood joist below. Two bits shattered in the space of 1 hours work. Not very impressed at all. I'm a very experienced DIY user, with over 35 years under my belt, and don't abuse tools, or push them past their limits. Never had a pozidrive bit shatter in all those years. Always thought Irwin products were decent. This was my first purchase of their products, but will be very reluctant to buy again.
