Great set. I bought this to replace a DeWalt set which works fine for me for drilling holes, but the pitch was such that they often yanked things out of my hands. These bits cut great without sticking. I will be buying another set to keep one at home and one in the shop.
The best daily flute set you can buy but don't sell in stores! It's only online, even at Home Depot. I bought them for drilling wood and plastic, but they work well for aluminum and thin metals. I clean the blunt ends of the little bits so they hold better in the chuck, everything works great.
I bought it again after about 5 years of use. They work great. The funny thing is that I bought it again because I've gotten so used to the case. This is a great case. Fits perfectly in my tool box and I love how the latch opens and closes. It also has enough space to put a few pieces in there. If you've found something that works, why change, right?
Pros
135 degree division point, accurate start without walking
