Hi guys, I hope you can help me - I am having trouble drilling deep holes in aluminium on my mini-lathe. I get about 30mm deep with no issues, but after that, I just can't seem to get the chips to eject cleanly, and the motor tends to stall. I have a mini-mill, so I am used to driling holes in stages and using various smaller diamteter drills, and peck drilling a few mm at a time, but I am still managing to stall the lathe, despite having twice as much power as on my mill!
I have tried squirting in a little WD40, but it's hard to get it into the hole when it's full of chips and drill bit. Any tips would be greatly appreciated!
Cheers.
