Is a carbide drill best or should I use an end mill? - toyota1515 - 09-10-2025
Hello, looking for some advice. I have a 6090 CNC router, which I use for wood. I would like to use it to drill 180 x 5mm holes in 15mm thick aluminium sheet. Having spent hours on Google looking for speeds and feeds I'm not really any closer to making a start. Is a carbide drill best or should I use an end mill? I do have coolant. Spindle power is 2.2kw. Any advice will be welcome
