The TE-AG 18/115 Q Li angle grinder offers cordless freedom, whether for grinding, cutting or polishing. It is equipped with a robust aluminum gearbox housing. The separation of the motor and gearbox ensures very quiet running. Thanks to the soft start and restart protection, the angle grinder starts smoothly and ensures greater user safety. The cutting disc can be attached to the cordless angle grinder without an additional socket wrench thanks to the so-called Quick Fix Nut. Changing the disc is completely tool-free and can be done in less than 10 seconds. The spindle lock is also recessed to protect against unintentional operation. The slim design with ergonomic soft grip and an additional handle that can be flexibly adjusted in two positions allows for comfortable handling of the device. The modified air flow ensures optimal cooling of the device and gentle work on the gearbox. Thanks to the quick adjustment, the windscreen protection can be adapted to any task in no time. Overload protection ensures greater safety and a long service life. The TE-AG 18/115 Q Li Solo angle grinder requires an 18-volt battery from the Power X-Change series, which is also used in other Einhell tools and garden tools.

Specifications

Same summary

The Einhell TE-AG 18/115 Q Li-Solo cordless angle grinder is a convenient choice, especially for users who already have an Einhell battery system or are looking for a tool for occasional, varied tasks in the home, workshop or outdoors. Due to the smaller disc diameter, the tool is particularly useful for more precise grinding and cutting in confined or difficult-to-reach places, but it is not the most suitable solution for larger cutting projects of thicker materials or long continuous use without a spare battery. An important compromise of this model is that the battery and charger are not included, which should be taken into account if you do not already have the appropriate components.

User view

Such cordless angle grinders often attract DIYers and hobbyists who need more freedom without annoying cables – for example when renovating, doing minor repairs or making furniture. The mobility of the tool is particularly evident when working in the garden, in the garage or when working in the field, where an electrical connection is not always available, and at the same time, due to its lighter design, it is also welcome when grinding at height or in difficult-to-reach areas.

Users often choose the Einhell brand because of its widely available battery system and the ability for all tools in the same ecosystem to be easily combined and adapted to the needs of an individual project.

Answers to frequently asked questions

Can I use any Einhell battery with the TE-AG 18/115 Q Li-Solo model?

This model is part of the Power X-Change platform, which means it is compatible with all Einhell 18 V batteries from this family.

What tasks is this cordless angle grinder best suited for?

It is suitable for cutting, grinding and shaping metal, tiles or concrete on a small scale, as well as for precision work and repairs at home or in the field where an electrical outlet is not available.

Is using a cordless sander safe even for beginners?

Due to its compact design and relatively easy use, it is also suitable for less experienced users, but it is recommended that you study the safety instructions and wear protective equipment before first use.

What should I do if I don't have a battery and charger yet?

If you don't have the appropriate 18V Einhell batteries, they will need to be purchased separately - this model allows for easy combination with other tools from the same series if you already use them.

Is a 115 mm disc diameter enough for most household tasks?

For most basic cutting and grinding tasks around the home, a 115 mm diameter disc is perfectly adequate, but for very extensive or deeper cuts, consider a larger model.
