You can call Hilti @ 800-879-8000 to see if they still carry parts for that model. It is actually a TM7S VSR.
Before buying brushes I would check the commutator segments to see if they are burned. Most times on that model if the brushes were bad then the armature was also bad.
If Hilti no longer carries parts check with Metabo. They manufactured that model for Hilti.
