Loosening or tightening screwsSometimes, it can be hard to start removing a screw using a cordless drill driver if its very tight. The tool can slip out of the screw head or may not have enough power to start |

With spindle lock you can use the cordless drill driver like a manual screwdriver, controlling the pressure on the screw and the speed at which you loosen it.
Spindle lock can also be used to finish off the tightening of a screw, so that you don’t drive it too far into the surface of the material. |
