GOOD angle aluminum?

[BrianG]

I was using the drill that came with the tap so the hole should have been the right size. Like I said, the drill seemed dull by comparison to the other drill bits I use. I think I will use oil next time like aqwut suggested.

Until the plastic bar stock arrives, I think I'll try another tap/drill set from my LHS and give it another go. I'll make sure to use the tips MM suggested along with oil. I think I have an odd quart of 10W30 laying around somewhere in the basement...

Procharged: Thanks! That's good info to have.
