Bộ Khoan Tay Cầm Kẹp Chốt

The collets swap out in seconds and hold bits firmly without any wobble, which makes drilling tiny holes in jewelry a lot less stressful. I’ve used it on a few delicate pieces already and the grip feels solid even when my hands get a little sweaty.

My model-making bench is tiny, so the compact size of this set is perfect for tight spaces. The secure grip on the handle makes precision drilling in small brass parts feel much more controlled than my old tool.

Finally a pin vise that doesn't slip mid-turn — the knurled grip keeps control even with my sweaty hands. Used it for a jewelry repair and the collet held a 0.8mm bit firmly without any wobble.
