Drilling/boring aluminium in the lathe
Hiya guys, I am in need of a faster way to create a large bore in aluminium. I need to make a hole 53mm diameter, 40mm (ish) deep in 6082 ali. I usualy bore it in the lathe after drilling a 20mm diameter clearance hole.
Unfortunately I am having so much trouble boring it afterwards, what with the nasty long chips inside that deep bore, I need an alternative.
I don't know a lot about drills, and have come across u-drills. Will these be a useful tool to use, or is there a better drill for my application? Any help appreciated here, thanks Jason.
Oh yeah, I need to keep the hole flat-bottomed too!
