The Einhell TE-AG 18/115 Li BL AXXIO angle grinder is a cordless machine which is suitable for use with 115mm cutting and grinding discs. Part of the Power X-Change family, it runs on a Power X-Change battery and shares battery compatibility with all other Power X-Change tools for the home and garden. One of the more advanced angle grinders that Einhell offer, the TE-AG 18/115 Li BL AXXIO has a brushless motor which means it can run for longer on a single battery charge (it is recommended to use a battery of at least 2.5ah capacity). Overload protection helps to prolong the lifetime of the motor, which also has a soft start for improved comfort and control. To protect the user, the grinder is restart protected - this means the switch automatically resets itself if it is left in the "on" position in between battery changes, and therefore won't start up unexpectedly.
