This is how I repaired the motor brushes for my Lidl Parkside Cordless X20V Grinder, PWSA 20-li B2, after they disintegrated without warning.
Manufactured in 2018 means I had about 5 years good hobby workshop use out of the grinder before something went wrong. Having been a useful tool and the batteries still in good condition I decided to try and mend it rather than bin it and buy a new one.
This appears to be a reasonably common failure on a common motor body so parts are available both locally and from China depending on how long you want to wait for them to be delivered.
I ordered a brush assembly from Aliexpress using the following search terms as putting a link up to this sort of item is worthless as listings in ALiexpress and Ebay are so volatile and subject to price change or just vanishing.
