Makita XAG09Z — 18V LXT® Lithium-Ion Brushless Cordless 4-1/2” / 5" Cut-Off/Angle Grinder, with Electric Brake, Tool Only

Makita delivers corded grinding performance without the cord with the 18V LXT® Lithium-Ion Brushless 4-1/2” Cut-Off/Angle Grinder with Electric Brake (XAG09Z, tool only, batteries and charger sold separately). It's powered by a Makita brushless motor for longer run time, increased power and speed, and longer tool life. For the most demanding applications, Makita’s exclusive Automatic Speed Change™ Technology automatically adjusts speed and torque during operation for optimal performance. For added convenience, the XAG09Z has an electric brake that stops the wheel in 2 seconds or less upon release of the switch. The XAG10Z is ideal for grinding, cutting and sanding a wide range of materials including tile, concrete, pipe, conduit, and more.
