I dug this one out from beyond the
grave back of the drawer.
If you remember I broke a tap in it and put it aside till now.
Well with my new "killer" drill bits, tungsen carbide tipped, I decided to have a go and see if I could drill the broken 5mm HHS tap out. There was a fair bit of it in there, but what the heck, nothing ventured and all that.
Set it up ready to murder, as Bogs would say, over the offending hole....

Well no real drama, used a 4.5mm bit followed by a 5mm. All holes now done

Even the tap behaved itself, on this one I tapped a little, fully retracted, tapped a little more and so on. It was tight as the drill bit got thrown off very slightly.
The reverse feature on the new mill was nice in this instance to retract the tap. (tapped manually though) New size was 6mm.

All done and grub screws inserted into their new home.

Well, I didn't expect this to work, but that's one project saved......
