The spring-loaded tip keeps constant pressure on the tap, which is a game-changer for starting holes in tight spots. I used it on a rounded engine block today and the threads came out perfectly straight.

I was tired of taps wobbling on curved surfaces, but the reversible point with the center hole for small taps finally gave me the control I needed. Works perfectly for starting those tricky holes straight.

I’ve been using this to start 1/4-20 threads in aluminum, and the reversible spring-loaded point keeps the tap aligned much better than my old method. The center hole for small taps is a nice touch, though I wish the overall body were a bit longer for deeper holes. Solid tool for the price.
