تغذية مثقاب حساسة

The knurled ring gives a really nice grip, makes it easy to control the feed for tiny holes. Works perfectly on my bench, the spring retraction is smooth and reliable every time.

The spring return is what sold me, it snaps back smoothly after each hole so I can keep a steady rhythm without fighting the tool. Drilled a bunch of tiny pilot holes in brass without any wobble or broken bits.

The knurled ring gives a solid grip even with slightly oily fingers, and the spring retraction is smooth enough that I don't have to fight it on tiny holes. Works exactly as needed for precise, delicate drilling without any wobble.
