"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."
"The case is the best part of this set. I am a full time handyman. The bits up to 4mm brake very very easily & they generally hold a edge for a very short period of time. If you are a occasional user then go for it but personally I would not buy again & will be sourcing better quality bits as having 1/2 a bit broken off in a pilot hole can be VERY irritating."
"These drill are not fit for purpose. Even when used I a pillar drill with the work piece clamped they snap with almost no pressure. The only good point is the box will be good to store my new Dormer drills in when they arrive."
