Einhell TE-AG 18/115 Li Review: Lightweight Cordless Angle Grinder
Cutting a rusted bolt on a ladder or grinding a weld in a tight corner is where cable-free grinders earn their keep. The Einhell TE-AG 18/115 Li is one of the lightest 115 mm cordless angle grinders in its class, built for exactly these short, awkward jobs where dragging out an extension lead makes no sense.

What Stands Out
Weight is the selling point: combined with a compact battery it stays comfortable for overhead and one-handed positioning work where heavier corded grinders tire your wrist quickly. The tool-free guard adjustment and left/right handle positions make it adaptable for both right- and left-handed users.
Where It Falls Short
Battery-powered grinding is energy-hungry. Long continuous cuts in thick steel will drain even a large battery quickly, so this is a tool for many short cuts rather than fabrication-shop duty. There is also no dust extraction port for masonry work.
Who Should Buy It?
DIYers and tradespeople already in the Power X-Change ecosystem who need a grab-and-go grinder for bolts, rebar, tiles, and cleanup work — especially on ladders, roofs and other spots far from a socket.
FAQ
How long does a battery charge last?
It depends heavily on the disc and material. As a rule of thumb, expect minutes of continuous grinding per amp-hour — enough for many short cuts, not for hours of fabrication.
Can it use standard 115 mm discs?
Yes, any standard 115 mm cutting or grinding disc with a 22.2 mm bore fits.
