螺旋推進鑽

As a model maker, I'm constantly drilling tiny holes in awkward spots, and this spiral action is a lifesaver where my pin vise just can't reach. The fact that it handles bits from #53 to #80 means I haven't had to switch tools once since I got it.

I've been using this push drill for jewelry work, and the spiral mechanism makes quick work of drilling into tight corners. It grabs even the smallest #80 bits firmly without slipping.

That tiny spiral action is a lifesaver for reaching awkward spots in my model work, and it handles those #53 bits much more smoothly than my old pin vise. I drilled a dozen holes in a tight corner without any hand cramping, which is a huge plus for fine detail jobs.
