blackleafforge Posted February 2, 2017 Share Posted February 2, 2017 I have been using a cheap set of drill bits that came with my drill for a while now and they are almost all broken or blunt. A fresh one only seems to last for about a minute of drilling through mild steel, is it worth investing in a very expensive set? I was looking at at 29 pice cobalt irwin set but it costs over £100. How much difference will I see? Does anyone else invest in expensive sets or is cheap and cheerful the way to go? Thanks Quote Link to comment Share on other sites More sharing options...
