Quick question, I need to drill out a deep wall socket slightly so that it engages with the hex on the DLE111 prop driver, I've managed to dill a few mm, but it's so hard, the drill won't go any further - any suggestions? I only need another 3mm depth.
TIA, Ell.

Re: engineering question
Hi Elliot, when we had to drill broken studs, that had hardened, we found masonary drills worked very well, slow speed, oil and quite a bit of pressure on the drill, you don't get an exact size hole, but it might suit your needs
best of luck Chris
