And, er buy a tool for extracting the broken ones from the holes...
broke a m36!!!!
They dont go much on being wound through with the windy gun Paul
Now my question is drill bit size with taps. I saw on the chart m10 tap but with two different cuts, 1.25 & 1.5, the chart said 1.5 needed an 8.8mm drill bit. How do you manage as 8.8mm is not a standard size drill bit or do you all just buy odd size bits for all your taps?
