Rank #7 in Best Angle Grinder 2026: 10 Ranked, and the Wattage Claims That Fail
Einhell TC-AG 18/115 Li Cordless Angle Grinder, 115mm
Price and rating as shown on Amazon when we collected them. Both change.
The Einhell TC-AG 18/115 Li is a cordless 115 mm (4 inch) angle grinder, seventh in this guide at £74.99, with 4.6 out of 5 from 68 ratings. The headline sells it as a set 'with Battery and Charger', and the Style field agrees: '+ Battery & Charger'. Its own first bullet does not — it calls the tool 'TC-AG 18 Li – Solo', which in Einhell's Power X-Change range means body only, no battery and no charger. Both statements sit in the same listing, so a buyer cannot tell from the page which one turns up in the box.
The ratings do not reconcile either. The header says 68 ratings; the star breakdown lists 78 five-star, 13 four-star, 7 three-star and 2 one-star, which is 100 in total. And where the cordless grinders above it in this guide quote wattage figures no 18V battery could deliver, this one quotes no wattage at all — the only performance number in the listing is an idle speed of 8,500 rpm. Everything on this page is read from the Amazon listing, not from our own testing.
How those 68 ratings break down
An average hides its own shape. This is the spread behind the 4.6 stars.
