"Got these as I go through bits like mad at times in my job, I like to sharpen drill bits but metal is so soft now days. Got this set and it's perfect for what I need. I filled my small bit set back up and keep it in my tool bag, while the metal box sits in my van or garage for when I need to re stock. Used it on all timbers and even the 2mm bit I put to the test of over 1200 holes in hard wood and still sat in my case now. Perfect. Good on metal too.. As you can see I couldn't recommend this set enough. Will last me many many years."
"...because they snap first. Don't try and drill anything much beyond hard plastics as they are very poor and weak. We are snapping them on a daily basis. Probably the worst drill bits I've ever bought. And one of the locking catches fell off the box on day one."
