I'm trying to mount a cheap Lowe's digital caliper on my milling machine's quill for a quill DRO.
I've gone through 3 drill bits and two hss end mills trying to get a hole for a 8-32 screw.
How in the heck can I drill this stuff? I'm going with very slow rpms, cutting fluid and trying to put plenty of pressure on the feed but all I'm doing is dulling bits and end mills.
I can't heat it to remove the temper because I don't want to risk damaging the electronics and I don't really want to...
