Rated 1 out of 5Â by JFisher Poor quality bits
I tried to use these to drill 6mm mild steel plate. I got about half way through before the cutting edge burred out on the bit. Drilling was done at low speed using a lubricant and cooling agent. Needless to say I was not impressed and had to return them as defective/not fit for purpose. Screwfix to be fair took the return no quibble.
Bottom line - these are poor quality.

This drill set is a good value set for getting over the problem of small chuck and larger hole required. I drilled out hole in solid steel block with no trouble, being quite rough on the drill bit with no problem.
One thing that would make this better and I would not object with the small raise in price is to provide some sort of case to keep them all together.

Good value set of drill bits if reduced shank diameter needed. But use a very slow drill speed with lubricant, works best with a pillar drill.
Rated 2 out of 5Â by marshal disappointing drill bits
To be fair, for the cost, I was unsure what to expect. Â£25 for 6 "blacksmith" drill bits seemed fair if they were good quality. I bought them for a tough job on 10mm steel. One actually snapped! and the others became blunt after one hole. Would not buy them again for a "blacksmith" type of job but for thin metal or wood then im sure they are fine.
