RATTMMOTOR High-Precision DIY Engraving Machine Mold Mini Right Angle Vise Clamp Working Range 50mm for DIY Mini CNC Router Milling Engraving Machine

This thing is made really well. I use it to hold small parts I tap.

This vise has many problems, first of all the grooves or rail like section has factory defect so when tightening it there seems to be an obstacle which does not let the vise close by just turning the screw alone. You need to unscrew it few times before you can tighten it. This item can be used just as a weak holder but definitely not precision vise. It becomes loose easily even if the work is properly fastened. When fastened with any size item in the vise , then the edges do not align .

Broke instantly. Don’t buy.
