Try Solent Power Tools (Southampton)(Google them) They make/modify brushes for just about anything, If the list on the website does not include your model, give them a ring. I have a Performance Rotary Hammer Drill which is obselete, the model was not listed, They modified a standard stock brush. I needed to modify it further (easy). The pair of brushes and postage was less that £10. Delivery inside 24hrs.
