Einhell TE-AG 18 Li Cordless Angle Grinder Review: Power & Portability 2026

Another power tool cuts the cord, reaching those awkward spots without the hassle of extension cables. It’s not every day you see a battery-powered angle grinder, but it’s all too common to watch someone drag meters of extension cord just to work on a fence, gate, or iron railing.

Lithium battery power and capacity have grown so much that these motors can now drive an ever-wider range of tools at very accessible prices. That’s exactly the case with the Einhell TE-AG 18 Li cordless angle grinder, a tool belonging to the Power X-Change family that shares the same 18 V battery with over 20 compatible tools—all of which can be purchased without the battery.

Thanks to the Soft Saft feature and safety protection against accidental start-up, the angle grinder runs quietly and is extremely versatile. The disc diameter is 115 mm, the no-load speed is 8500 rpm, and the gear housing is made of aluminum.

Key Features

Adjustable Guard & Quick Lock

The protective guard fits onto the head collar, just like on all these machines. Here, the collar is secured by a lever clamp that makes adjustments super quick—perfect for orienting the grinder exactly as needed for each task.

Three-Position Auxiliary Handle

The additional handle is highly versatile, with three mounting positions: left, right, and top of the machine body. This gives you total control no matter the angle of attack.

Integrated Wrench Storage

The flange nut wrench, needed for changing the disc, is always within reach because it’s stored right inside the auxiliary handle. No more hunting for tools mid-job.

Easy Disc Changes

Tightening and loosening the flange nut requires just one tool—simple and efficient.

Why Go Cordless?

If you’ve ever wrestled with extension cords while working on outdoor projects, you’ll appreciate the freedom of a cordless grinder. Pair it with a quality garden supply setup or use it to prep outdoor patio furniture for refinishing. The 18 V battery platform means you can also power drills, saws, and more—all from the same battery.
