GodHand GH-PBQ Quick Power Pin Vise

The hexagonal connection fits securely together, so it won't spin freely!
The magnetic system makes it super easy to attach and detach the drill bit!

If you have a 4mm hexagonal shaft, you can simply insert it into the pin vise and it will be installed! It
fits perfectly with the magnet, so there is no need for any troublesome adjustments.
Also, because it is a hexagonal shaft, it fits securely with the connection part of the pin vise, so there is no need to worry about it spinning freely.
It is ideal for those who want to process things faster.
It goes great with quick drill bits!
