Hi all,
Listen, I am the first one to say that Guhring makes a top notch drill, but I think I may try something else in the near future. We mostly use Guhring for HSS & powdered metal drills and use GARR for carbide drills.
Anyway, we keep having problems with the recently purchased Guhring drills. They keep cutting oversize. I am not sure why. We indicate them in the drill chuck on the cnc mill every time we use them and they still cut way oversize.
We are a two man shop and sub work out to another shop when we get too busy. Today, the machinist at the other shop called and asked if an oversized hole in the part he was working on for us would be okay. He said that the Guhring drills he had were ground off center and cut the hole oversize. He then said that a couple years ago, he had to return a whole bunch of Guhring drills because they did not have the tips ground on them.
Anyway, has anybody else noticed quality control issues with their Guhring drills? I mean for the money you pay for them, they better damn be near perfect.
I think I am going to give Nachi drills a go.
Any thoughts?
Thanks,
Chris
