GTIWUNG 10 Pcs Mini Pin Vise Hand Drill Bits, Micro Twist Drill Bits Set with Precision Hand Pin Vise Rotary Tools for Jewelry Carving Woodworking Plastic (0.8-3.0mm)

Only negative is the pin vise won't clamp down on bits smaller than 3mm.

The pen vise will not fit half the bits included. The smaller half of the bits will not fit in the pen vise, the pen vise cant clamp down that small. what's the point of even including the pen vise?

El tamaño de las brocas no se ajustan al taladro, y quedan bailando.

Drills dull and essentially 0 degree point angle. May be able to grind through plastic on a good day. Pin vise is marginally useful, but the reversible collet covers two discontinuous ranges of sizes and the threads are roughly cut.

Useless. Biggest bit doesn't fit and smallest bits don't tighten at all. Used for the first time and return window is closed. Complete waist of money.

Poor quality, broke after a couple of uses. Unable to put the bit into the base and broke.

Pin vise won't work with the smallest four out of the ten bit set. For me the set is of no use because of that. In the products description they claim that the pin vise will clamp on to all sizes in the set, .8 mm thru 3.0 mm.

I did not receive the pin vise shown in the picture.
