Another Advantage of New Sharp Taps
This should be obvious, but along with cutting threads more easily a new sharp tap has another advantage when you are using a drill press to tap threads. I use a drill press rather than a T-handle because you get nice 90 degree threads that way. Sharper tap means it takes less clamping force in the chuck to hold the tap in place, because there is less force coming back from the tap being so sharp.
