A job came into the shop that needed a bunch of holes tapped. They were 8-32's...all 244 of them. Unfortunately, my '87 Fadal did not come with the rigid tapping optional. So, I initially resorted to my tapping head for the drill press. Since it was aluminum, I used a diesel fuel as the tapping lubricant. I usually have great success with it. The problem was that the tapping head was taking way too long. I was also having to fight with it.
So, I figured I would take a chance and try tapping with the cordless drill. I had to change my tapping fluid to Anchor Lube. This stuff is fantastic. I originally got it for tapping stainless and titanium, but boy, did it do a wonderful job. I set the clutch on the drill at a very low setting. This prevented me from breaking a tap as well as helped make sure I was tapping straight. 240 holes in about 10 minutes, not too bad...with a very nice finish I might add...
