You can easily connect your angle grinder to the holder by attaching the spanner. To do this, simply attach the spanner to the holder and you're ready to go. If needed, you can also remove the spanner from the holder for added convenience or make a hole in the holder for the grinder spindle, allowing you to use the spanner without ever having to take it out of place again.
