Project: Aluminum Nose Bushing,
Material 3/8 6160 T6 rod,
Operation drill through, .094, turn to .171 by .700, cut off .740.
Machine, Ames turret lathe. Time 1 min 50 sec.
Tap Magic for aluminum. Drills and turns easily, three to four pecks to drill .750 deep. rough turn from 3/8 to .180 in one pass, good chip control, clean cut. Finish at .171, feed both ways.
Tap Magic for all metals (recent case purchase) four to five pecks to drill .750 deep. rough turn takes a little more pressure (hand feed) a bit less chip control (strings ball up a bit. Finish pass about same as T M Aluminum.
Both Tap Magic cans are four ounce, easy to hold in left hand and drip as needed on tooling.
Relton A-9 (this specifies its for aluminum on the can) Drills .750 deep in 4 to 6 pecks, doesn't seem to affect ease of cut or chips at all, smokes considerably more than either Tap Magic. The can is a 16 oz can with a 3 inch spout, Its much less easy to control the can/spout and put a drop as needed on the tool. If it were in a Tap Magic can this would be eliminated. It leaves the work considerably more oily. Ditto operators hands.
Conclusion, For aluminum the Tap Magic (Aluminum) is best, followed by Tap Magic for all metals. I only wish half the cans of Tap Magic I bought last week were for aluminum, The one can purchased a year ago is almost empty.
