I have a Grizzly mill, and have been installing a DRO on it. I've drilled and tapped (5mm) about a dozen holes on various cast iron parts, and have suddenly been unable to make any progress on a hole. No, I'm not running the drill backwards! I've replaced the HSS drill bit, and have tried the Dremel with carbide, and now (2mm) diamond drills to pilot, and have barely made 1/4" progress. I started the hole the same way as all the others, and it just ain't the same. I drilled & tapped another part of the base (about 2' away) without issue.
Any suggestions?
Thanks,
Brian
