Broken tools
Tools Break. This is not a problem - it's expected. Appropriate communication can help get replacement or repairs done promptly.
This generally applies to power tools.

What to do if a tool breaks
Add an orange 'Broken Tool' tag and place with the tool in the 'Broken Tools' box. If the tool is fixed or nor practical to place in the box add the tag in such a way that it's obvious that the tool is broken and no attempt should be made to plug it in or use it.
Send an email to tools@nottinghack.org.uk reporting the breakage. This will accelerate getting a replacement or organising repairs.
