If you have a broken die grinder, there may be times when you need to make repairs. One way of doing this is to take it to a tool repair shop, or to your home improvement store, and see if they can fix the problem for you. This is probably the best way of ensuring you get the die grinder working to its best again, but if you do not have enough money to have the grinder sent away, or if you want to get on with some work, and need the grinder working again quickly, then there are some simple things you can do to ensure the grinder is fixed.

Step 1 - Check the Power Supply

If you have a problem with the die grinder not powering up, then one of the reasons may be that the power supply has become damaged, or won't work. It is also a good idea to remove the power source before you begin poking around in the rest of the grinder, so firstly unscrew and remove your power source. Look at all of the wires which connect the battery to your device and look for signs of shorting.

You may need to replace the fuse if you see signs of damage. Remove the wires from the battery and add a new power source. Check the grinder to see if this has solved the problem, and if it has not, remove the power source and place it aside.

Step 2 - Clean the Die

The next step may be to clean out your die grinder. Regular grinding can cause the tool to become dusty, and this dust can also get into the way of the grinder's operation. Firstly, remove all of the parts you can and wipe using a cloth and some electrical cleaning powder, which is a safe way of cleaning without using water. Scrub all of the parts, and ensure there is no dust or debris on any part. You may then be ready to restart the grinder, but if this has not worked, then you may need to try another solution.

Step 3 - Remove Dirt

With a die grinder, parts can become lodged beneath the die of the tool, and this can prevent it from turning. Using a pair of needle-nose pliers, run them around the outside edge of the die. If necessary, you can remove the sanding pad, which is on the surface of the die, and search underneath this pad for signs of damage. You may find there are chips of wood caught along the moving parts of the die grinder, which is preventing it from turning properly. Remove these chips, add a new sanding pad, and you should find that the grinder works again.
