مثقاب وناقل مركزي، صغير

The spring-loaded cone slides so smoothly in the outer cup that it stays perfectly square against the template, even on uneven surfaces. Pressing down on uneven metal didn't shift the mark a bit, which is exactly what I needed for a quick transfer job.

I've been using this to transfer hole centers from templates with different hole sizes, and the spring-loaded cone makes alignment dead simple. It presses flat and stays square against the workpiece, taking the guesswork out of positioning.

Took a bit of practice to get the spring-loaded cone to seat cleanly each time, but once I got the hang of it, hole transfers are spot-on now.
