Drill bit for brass

[CNCDev]

Hi Boyan, thank you, a very informative thread. It is amazing how fast you can drill these holes! My converted CNC mill is limited to 9000 rpm and I will adjust to that.

I think I just try out the drill bit I have linked to. I can buy them for £5.35 through the company I work for, so it's not that much. The Format brand seems to be quite reputable, so I don't have big concerns with the quality.

I just want to mention that I don't actually buy stuff through the company, I just make "small" jobs now and then on my RF-45 and they pay me with tools and material. I like that very much, because then I can do my hobby and get a lot of good quality tools for "free" and they will always come in handy for other jobs :-)

This job though, is for a different customer and my first series production. This is the reason I ask for help, because it certainly has great impact on choosing the right tool for the job when doing series production and I just wanted to hear if there was a better alternative.


Regards,

Brian
