Per the title, is it just me or do most drills just seem to suck now?
I've been having one hell of a time trying to find twist drills these days that don't have a fantastic tendency to lobe like mad and it's driving ME mad..
It doesn't seem to matter brand or place of manufacture, almost every twist drill I've had my hands on lately doesn't want to make a round hole with acceptable finish. It's not my machines or drill chucks; they're good to go and I run the drills straight from a collet in my Tree 2uvr 90% of the time. I've been drilling holes for a proper minute now and I don't think my technique sucks THAT bad and I don't ever remember having so much trouble.
The only thing that strikes me as being the culprit is today's uber aggressive grinds. You find them even on super cheap drills and I'm beginning to suspect that without a bit of center web rubbing,
you have serious lack of stabilization for the bit. The old drills used to have plain webs, now almost none do no matter the price.
The only drills I'm remotely satisfied with these days are U.S. made stub length drills. IS IT JUST ME?
Edit: Mostly drilling mild steel and try to stick to 135 points...
