Einhell 115mm vs 125mm vs 230mm angle grinder

Updated: October 2026

With 50 mm paving flags or rusted M10 bolts in the garden, an Einhell 115mm vs 125mm vs 230mm angle grinder is a depth question. The disc decides whether the wheel clears the cut in one pass. On our 19 October 2026 [Einhell angle grinder comparison](/hub/tools/einhell-angle-grinder), Peter F., DIY & tools editor, read eleven amazon.co.uk listings and Einhell UK sheets, without a laboratory cut. A larger disc adds reach, and it also decides whether you can stay on an 18 V body or must lift a 230 V machine. This page matches the depths Einhell prints to the shelf weights.

What 115, 125 and 230 mm means here

Seven tools are 115 mm: two corded bodies near £33, two bare 18 V solos at £39.98 and £43.83, the 4.0 Ah kit at £69.50, a title-only set at £81.28, and the brushless AXXIO 18/115 at £84.95. Cordless 115 mm machines run at 8,500 rpm. The corded pair spin at 12,000 rpm and 11,000 rpm. 125 mm here is bare 18 V only: TP-AG 18/125 CE Q at £104.00 (3,000–10,500 rpm) and flat-head TP-AG 18/125 F at £104.99. At 230 mm, TE-AG 230/2000 (£68.99) and TE-AG 230 (£82.59) are corded tools at 6,500 rpm. The nominal diameter is not the cutting depth.

Depth Einhell prints, and the class figures

Screwfix and ITS Hub quote about 30 mm, 38–40 mm and 70 mm for 115, 125 and 230 mm discs. Those are exposed-radius rules of thumb. The gearbox and flange stop the disc earlier. Einhell prints 28 mm for the 115 mm class, in the highlights for B00SWDG056 and B0CNTRXZSY and on the Einhell UK page for the corded TC-AG 115. Both 125 mm listings state 33 mm, not the 38 mm class estimate. Amazon leaves depth blank on the 230 mm tools. Einhell UK pages for 4430840 and 4430870 state 62 mm, not 70 mm.

What the tools weigh

Stated weights on the smaller tools run from 1.54 kg on the corded TC-AG 115 to 2.25 kg on the 4.0 Ah kit. One listing prints no weight. At 230 mm, amazon.co.uk lists 5.63 kg for the 2,000 W tool (5.4 kg on Einhell UK) and 6.4 kg for the 2,350 W tool (5.5 kg on Einhell UK). That weight needs two hands.

Which diameter matches the cut

Bolts and mortar to 28 mm start on a 115 mm tool unless you need variable speed. UK reviewers use the 500 W TC-AG 115 (£32.95) on mortar. It has no soft start. Bare bodies against the £69.50 kit are in our Einhell corded or cordless angle grinder guide and the Einhell angle grinder buying guide. 125 mm is the step when 33 mm clears the stock. The CE Q drops to 3,000 rpm. The flat head reaches welds down to 43°. Both are bare. 230 mm is for masonry up to 62 mm on the Einhell UK sheet, and UK reviews on those two corded tools also report first-use failures.

Common questions

Is a 115 mm Einhell angle grinder enough for paving slabs?
A 115 mm Einhell cuts to a printed 28 mm, enough to score a slab or cut thin porcelain. It will not sever a 35 mm to 50 mm concrete flag in one pass. For a printed depth up to 62 mm, Einhell UK points to the corded 230 mm TE-AG 230/2000 or TE-AG 230, at 5.63 kg to 6.4 kg, and that is a two-handed machine.
What cutting depth does Einhell print for its 115 mm grinders?
Where cutting depth is stated on the 115 mm listings, Einhell prints 28 mm. That appears in the amazon.co.uk highlights for the cordless TE-AG 18/115 Li Solo (B00SWDG056) and AXXIO 18/115 (B0CNTRXZSY), and on the Einhell UK shop page for the corded TC-AG 115. That is 2 mm shallower than the 30 mm rule-of-thumb figure cited in generic UK hardware buying guides.
How heavy are the Einhell 230 mm angle grinders on amazon.co.uk?
On amazon.co.uk, the 2,000 W Einhell TE-AG 230/2000 (B00IGQZFTQ) lists an item weight of 5.63 kg, and the 2,350 W Einhell TE-AG 230 (B00BLZXTP6) lists 6.4 kg. Both figures are higher than the 5.4 kg and 5.5 kg tool weights on Einhell UK’s shop pages. Both require two-handed operation, and neither is a one-hand 115 mm job.
Why is Einhell’s 62 mm cutting depth different from the 70 mm class figure?
Retailer buying guides from Screwfix and ITS Hub use 70 mm as an approximate class figure for 230 mm discs across brands. Einhell’s UK product pages for the TE-AG 230/2000 (4430840) and TE-AG 230 (4430870) specify a maximum cutting depth of 62 mm once the gear housing and clamping flange are taken into account. The amazon.co.uk tables for those two listings leave depth blank.
When does the 125 mm flat-head grinder matter?
The Einhell TP-AG 18/125 F (B0DPG9L5XF, £104.99) matters when you grind weld seams, slag or rust inside tight steel corners where a standard gearbox would foul the workpiece. Its low-profile head works at acute angles down to 43°, with a 33 mm cutting depth and a 1.57 kg bare-tool weight. You supply your own 18 V battery and charger.
