This is a Godhand Quick Power Pin Vise

The GodHand Quick Power Pin Vise / Vice has a hexagonal shaped connection and fits tightly, so it won't spin freely. It's also magnetic, making attaching and detaching the drill blade super easy.

With a 4mm-diameter hexagonal shaft, installation is completed just by plugging! Thanks to the magnetic fit, there are no complicated adjustments making it ideal for faster processing.

The rotating washer features a slim, smooth design that fits comfortably in the palm of your hand. This also minimises obstruction and feels ergonomic, making it is easy to hold with a stable feel, whilst ensuring smooth operation with less blurring.
