Hi there

Can anyone tell me the best way to drill holes with a shapeoko in aluminium?

I'm having real trouble. I have 1/8 drill bits that cut metal like butter in my drill. I did a project today where I wanted to drill 8mm ali. Within 3 holes the bit snapped - tried another time - also snapped. Issue is even at 5mm a min the drill is still spinning at 16000 rpm?

I'm using the drill function is fusion 360.

Thoughts?
