Metabo 18 V angle grinder buying guide

Updated: 22 October 2026

You already know you want a Metabo cordless angle grinder, and the name still reads like a parts code. A 7, a 9, the letters BL and a 125 change the tool, while the pound figure on amazon.co.uk often leaves the battery out. This Metabo 18 V angle grinder buying guide puts those tokens in one order, then points each of them at a listing in the [Metabo cordless angle grinder comparison](/hub/tools/metabo-cordless-angle-grinder). Shelf prices are the figures from 19 October 2026. We did not lab-test these tools. A qualifying purchase can earn a commission at no extra cost to you.

What the model name is telling you

On Metabo’s 2023 range sheet, 7 is about 700 W, 9 is about 900 W, and the flat-head’s 15 is the 1,500 W class. BL means brushless. Quick means a quick-locking nut. The trailing 125 is the disc in millimetres. The W 18 7-125, order 602371850, is £68.99 and does not say brushless. Order 602374850 is the cardboard brushless body at £74.95, with one review and no text. Order 602374840 is the metaBOX body at £125.45, with no star line. On the flat-head, “as powerful as a 1,500 watt mains-powered tool” is a class label, not a measured battery input. Models outside this seven-row set get no price here.

125 mm, 76 mm, or a flat head

Maker sheets give the 125 mm tools an M14 spindle. A disc marked slower than the tool is the wrong disc. The CC MetaLoc, order 600349840, is £42.97, and review text says 76 mm, with M5 on the maker sheet. A 125 mm disc does not belong on it. Order 600349850 at £142.27 does not state a diameter. The WVBF reaches 43° on a 125 mm disc. Corner welds are on the flat-head page. Guard and nut are on the how to use a cordless angle grinder page.

The price is usually the bare tool

Six of these seven titles exclude the battery. The £142.27 CC is not stated, so read that listing on the day. A metaBOX is a case, and the £125.45 brushless body is still bare. Metabo’s LiHD page gives no minutes: 4.0 Ah at 72 Wh and 580 g, 5.5 Ah at 99 Wh, 8.0 Ah at 144 Wh, and 10.0 Ah at 180 Wh. Reviewers of the 7-125 say about 2 Ah runs out very quickly. Read the body-only page before you treat £68.99 as ready to cut.

Where the seven listings sit

If you own the packs and want light 125 mm work, open the W 18 7-125 at £68.99. If the listing must say brushless, the cardboard 9-125 at £74.95 has one review, and the metaBOX at £125.45 has a display score of 0. A tight gap is the £42.97 CC. A corner the standard head misses is the flat-head at £245.77, still without a pack. A 5.0 from one review is weaker than 4.6 from 158. A score of 0 means the star line was missing.

Common questions

What does the 7, 9 or 15 in the name mean?
On Metabo’s 2023 range sheet those numbers are watt classes of about 700 W, 900 W and 1,500 W. On the flat-head, “as powerful as a 1,500 watt mains-powered tool” is the maker’s comparison. It is not a measured battery input.
Does BL mean brushless, and is the W 18 7-125 brushless?
BL on the W 18 L BL 9-125 means the listing says brushless. The W 18 7-125 bullets do not say it, and reviewers of that £68.99 listing report brushes. Compare order 602374850 at £74.95 with order 602374840 at £125.45 if the motor has to be brushless.
Is 125 the disc size in millimetres?
On these names, 125 is a 125 mm disc. Review text on the £42.97 MetaLoc says 76 mm, with an M5 spindle on the maker sheet. The 125 mm sheets give M14. The £142.27 CC does not state a diameter, so do not borrow 76 mm for it.
Do I need a battery as well as the tool?
You do, unless you already own an 18 V CAS pack and a matching charger. Six listings are marked battery No. The £142.27 CC is not stated, so read that page on the day. A metaBOX does not replace the pack. Metabo points at 4.0 Ah as a compact pack and 5.5 Ah for the hardest jobs, with no minutes published.
What is the difference between the two W 18 L BL 9-125 order numbers?
Order 602374850 is £74.95 in cardboard, with 5.0 from one review and no text. Order 602374840 is £125.45 in a metaBOX, with no star line. Both are 125 mm at 10,000 rpm and exclude the pack. Only the cardboard row prints the safety-shutdown sentence.
When is the 76 mm CC the wrong tool?
It is the wrong tool when the cut needs a 125 mm disc. The £42.97 MetaLoc is a 640 g compact at 20,000 rpm for narrow gaps, and one reviewer says it is not a full-size grinder. Open bar stays on the 125 mm rows.
Which pack size do people actually name for grinding?
Reviewers of the W 18 7-125 say a pack around 2 Ah runs out very quickly, and they name about 4 Ah to 5.5 Ah. Metabo’s LiHD roles sit in that range, then 8.0 Ah and 10.0 Ah for longer runs. No source here publishes grinding minutes. Do not paste that complaint onto a listing that has no reviews.
