I'll pile on to the rest - just pick up SCLCR/L (RH & LH) holders in whatever size you like, and a pack of aluminum/nonferrous inserts. McMaster sells Dorin holders at ~$48 each, and the aluminum specific inserts are $6.90/ea for a box of 10 (3244A316 or 3244A318). I forget the brand of the inserts, might be Mitsubishi.
Shars also sells the "CCMT" style aluminum specific inserts, they're listed as CCGX on their site. Never tried them, but in case you wanted to pick up the boring bar/holder cheaper from them.
