"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."
"Great selection of different bit sizes and for the price. However, from experience, as soon as you start drilling metals (I've used them on steel and aluminium) the bits are becoming blunt before they've drilled one hole! (in 6mm mild steel plate)
Others have mentioned the benefits of keeping this bits organised, that's fine until the case is dropped and your smaller bits have jumped ship into other compartments.
Clearly this product is manufactured for quantity rather than quality. My recommendation, spend a bit more money and get a decent set of HSS bits"
"Ok, I wasn't expecting much for £40 and its a good job. As another review said this set is great for keeping your drill sizes organised but not much else. The drills havent been properly sharpened and when you look at a half drilled hole it looks more triangular than circular. Half the drills also appear to be slightly bent straight from the box. They haven't been properly hardened either, if you use them on mild steel they start screeching with agony after a second or two and are basically blunt straight away (including when using proper cutting fluid). The drills will also bend even with the slightest bit of missalignment when half way through a hole, this includes the larger sized ones as well. These may be ok for drilling wood or plastic but forget it if you are looking to make holes in anything tougher. My plan is to use up what is in the box (shouldn't take long) and replace them with decent HSS stuff. Sorry but I wouldn't recommend this product for metalworking."
