The best Metabo circular saws, compared.
Top pick: KS 18 LTX 57 BL bare Best value: KS 55 FS + FS 160 – The FS 160 rail and the case are named in the title at about £274.69, so you are not buying the rail as a second order. Updated October 2026.
A Metabo circular saw is one of five amazon.co.uk listings kept after seven non-Metabo captures were removed. The KS 18 file is 5.0 from only four reviews. The KS 85 kit has no star line in the capture. Depth, box contents and pack cost are in the [Metabo circular saw buying guide](/hub/power-saws/metabo-circular-saw/sub/metabo-circular-saw-buying-guide). The set is two corded FS hand saws in the KS 55 class, one corded KS 85 FS kit, one 18 V hand saw and one 18 V plunge saw. Mitre saws and table saws are different tools and are not scored here.

Question 1 of 2
How will you power the saw?
The Metabo KS 18 LTX 57 BL at about £159.95 is the CAS hand saw with 57 mm at 90° on Metabo’s UK sheet, a brushless motor, a brake and a rail-ready shoe, sold body-only with a metaBOX 340. On-rail depth on that sheet is 52 mm, on a 165 × 20 mm blade, with bevel 0–50° and a detent at 45°. Amazon shows 5.0 stars from only four reviews, so the file is thin against the corded KS 55 listings. The scope lists a blade, a parallel guide, a hex wrench and the metaBOX, not a battery, a charger or a rail. Price a Metabo or other CAS 18 V pack before you compare this sticker with the corded body at about £147.99. The listing weight is 3.7 kg. The Metabo sheet states 2.7 kg without a pack. Listing bullets say the aluminium base fits Metabo and several third-party guide rails. KFS cross-cut rails are optional extras.
Pros
Cons
Best for: You already run Metabo or other CAS 18 V packs and you want a cordless hand saw on site.
Less suitable: This is your first cordless saw and you have not priced batteries, or you need a large UK review sample.
Specifications
Common questions
Does the KS 18 LTX 57 BL include a battery?
No. The scope lists a blade, a parallel guide, a hex wrench and a metaBOX 340 only. The shelf price is the bare body.
What depth does the name 57 refer to?
Metabo’s UK page states 57 mm maximum cutting depth at 90°. On a rail the same sheet states 52 mm.
Can it use Festool or Makita rails?
Listing bullets say the aluminium base plate fits Metabo rails and several third-party guide rails. A rail is not in the box.
The Metabo KS 55 FS at about £147.99 is the corded FS hand saw in this set with the largest review sample on amazon.co.uk, 4.7 from 227 ratings. Much of that text is EU, on a Spanish-titled listing. Metabo’s sheet gives 55 mm at 90°, 39 mm at 45° and 50 mm on a guide rail, on a 160 × 20 mm blade, with an FS groove for Metabo or third-party rails. The scope lists a blade, a parallel guide and an extraction piece, not a rail and not a case. Buyers praise the build and the rail fit against Festool and Makita tracks, and they also note chip clogging. It is a mains saw. A stray battery row on the listing is not the product. Bevel on the Metabo sheet is 0–47°, the listing speed is 5,500 rpm, and the weight row is 4 kg.
Pros
Cons
Best for: You want a corded FS saw and you already own a guide rail, or you will buy one.
Less suitable: You want a one-box track kit, or you need the reviews to be UK-written only.
Specifications
Common questions
Does the KS 55 FS include a guide rail?
No. FS marks the groove in the shoe. Metabo’s scope lists a blade, a parallel guide and an extraction piece only.
How deep does it cut at 90°?
Metabo’s KS 55 FS page states 55 mm at 90° and 50 mm when the saw is used on a guide rail.
Is a battery included?
No. This is a corded mains saw. Ignore the stray battery row on the amazon.co.uk listing.
The Metabo KS 55 FS set at about £274.69 is the only capture here that pairs the KS 55 FS with an FS 160 rail and a case in the title, at 4.6 from 158 reviews. It suits straight breaks on site when you want the Metabo rail and the saw together. Reviews warn that the long rail is awkward in tight rooms, that the first cut can trim the rail lip, and that one buyer shimmed the blade height to protect the rail edge. Clamps are often bought separately. The title describes a mains saw. The battery-powered row on amazon.co.uk is listing noise. Depth stays in the KS 55 FS class: 55 mm at 90° and 50 mm on a rail on the Metabo sheet. The listing speed is 5,600 rpm and the saw-unit weight is 4 kg.
Pros
Cons
Best for: You want a Metabo rail and a KS 55 FS in one purchase for straight sheet or carcass cuts.
Less suitable: You work in a tight room with no space for a 1.6 m rail, or you already own a rail.
Specifications
Common questions
Is this listing cordless?
No. The title describes a KS 55 FS mains saw with a case and an FS 160 rail. The battery-powered row on amazon.co.uk is listing noise.
What rail length ships?
The title names FS 160, Metabo’s 1,600 mm FS guide rail family.
Do you need extra clamps?
Reviews often buy clamping wedges separately. They are not listed in the included-components field.
The Metabo KT 18 LTX 66 BL at about £359.00 is the cordless plunge saw in this set. Bullets claim 66 mm depth, variable speed, undercut and a 42-tooth wood blade, in a metaBOX 340, body-only. A dust bag is in the scope. A guide rail is not. Reviews praise cut power on Festool rails with larger packs, including 5.5 Ah, and call a 2 Ah pack too weak. Several buyers report a metal shoe that does not sit flat until the saw is returned. The amazon.co.uk line is 3.9 from 33 reviews. Check the shoe on delivery before you keep it for rail-critical work. It is not a KS hand saw: the guard and the plunge entry are different. The listing speed is 2,250 rpm and the weight is 4.3 kg.
Pros
Cons
Best for: You own CAS packs, you want plunge cuts, and you will inspect the base on arrival.
Less suitable: This is your first saw, or the job is only freehand ripping with a KS hand saw.
Specifications
Common questions
Is this the same as a KS hand saw?
No. KT is a plunge-cut saw. The guard and the entry technique differ from the KS FS hand models.
Why do reviews mention a warped base?
Several buyers writing in German and French report that the metal shoe did not sit flat on a table or a rail until the saw was returned.
Which battery do reviewers use?
Captured reviews mention 5.5 Ah Metabo packs working well and 2 Ah packs as too weak. No battery is in the box.
The Metabo KS 85 FS set at about £613.79 pairs a 2,000 W KS 85 FS saw with a KFS 44 timing rail, a 24-tooth carbide blade and a parallel stop in the scope. It is the heavier corded kit in this set, listed at 8.4 kg. The capture prints no amazon.co.uk star line, so there is no review score to rank it on. It also does not state a depth at 90°, so this page leaves that cell empty rather than filling a figure the capture does not give. Compare it on kit contents: the timing rail is in the box, which the bare KS 55 FS does not include. It is a weak match if you need a review file before you buy, or if the budget is the KS 55 class.
Pros
Cons
Best for: You want heavy corded cuts with a Metabo KFS cross-cut rail in the same box.
Less suitable: You are buying on a DIY budget, or you need amazon.co.uk review evidence on the listing.
Specifications
Common questions
What is KFS 44?
It is Metabo’s cross-cut timing rail, named in the scope line for this KS 85 FS set. It is not the FS 160 rail from the KS 55 set.
Does this listing show reviews?
The captured amazon.co.uk file has no customer-reviews line, so this page does not show a star rating or a review count for it.
Is it lighter than the KS 55 FS?
No. The capture lists 8.4 kg item weight, heavier than the 4 kg rows on the KS 55 FS listings.
Shelf prices, stars and review counts are the amazon.co.uk listings for these five Metabo saws on 20 October 2026. These saws were not lab-tested. Seven non-Metabo listings were removed before scoring. The top pick is the KS 55 FS, once. Best value is the KS 55 FS set with FS 160, once, because the rail is named in the title. Weights sum to 100.
Amazon evidence
30%Stars and review count on the amazon.co.uk capture. A file under 25 reviews is penalised heavily. The KS 55 FS is 4.7 from 227 reviews. The FS 160 set is 4.6 from 158. The KT 18 is 3.9 from 33. The KS 18 is 5.0 from only four reviews. The KS 85 kit has no star line in the capture, so it cannot be scored as if it had a review file.
Listing fit
35%Depth has to be sourced, an FS or KFS rail has to be true to the title or the scope line, and a bare CAS body has to be labelled as body-only. A battery row on a corded listing is noise and is not scored as a feature. The KS 85 capture does not state depth at 90°, so that cell stays empty.
Review outcome
20%Review themes that change the cut: rail-lip trimming and shimming on the KS sets, and a base that does not sit flat on the KT 18. Those notes stay with the product. A high star line with four reviews is not treated as the same outcome evidence as 227 reviews.
Value
15%The price is judged against what ships. The FS 160 set is best value because the rail and the case are in the title, against buying a rail separately for the bare KS 55 FS. A CAS sticker is not a finished price until you add packs. The KS 85 kit is the dearest row because the KFS 44 rail is in the box.
Choose depth, then whether a rail ships, then mains or CAS, before the lowest sticker. These five amazon.co.uk listings were captured on 20 October 2026. The KS 55 FS body is about £147.99. The KS 18 LTX 57 BL bare is about £159.95. The KS 55 FS set with FS 160 is about £274.69. The KT 18 LTX 66 BL bare is about £359.00. The KS 85 FS with KFS 44 is about £613.79. The top pick is the bare KS 55 FS. Best value is the FS 160 set when the rail should be in the box.
A Metabo circular saw, in this comparison, is one of five amazon.co.uk listings that stayed after seven non-Metabo captures were removed. The set is two corded FS hand saws in the KS 55 class, one corded KS 85 FS kit, one 18 V CAS hand saw and one 18 V CAS plunge saw. Mitre saws and table saws are different tools and are not scored here. Prices on 20 October 2026 run from about £147.99 to about £613.79. Depth and blade size come first. The KS 55 FS takes 160 × 20 mm blades.
The KS 18 LTX 57 BL at about £159.95 and the KT 18 LTX 66 BL at about £359.00 exclude the battery and the charger. CAS means a pack you already own, or a pack you still have to buy. Compare those stickers with a corded price only after the pack is in the sum.
FS on a KS model is the groove in the shoe. The bare KS 55 FS does not ship a rail. The set that names FS 160 does. The KS 85 set names KFS 44, which is a cross-cut timing rail, not FS 160. Clamping wedges are often a separate buy.
A KS hand saw is not a plunge saw. The plunge model here is the KT 18 LTX 66 BL. Reviews on that listing include bases that did not sit flat. Check the shoe on arrival, and do not dry-sweep MDF dust.
Depth at 90° is the cut you can make in one pass, and a bevel reduces it. Metabo’s KS 55 FS page states 55 mm at 90°, 39 mm at 45° and 50 mm on a guide rail, on a 160 × 20 mm blade, at the 1,200 W class. The KS 18 LTX 57 BL is 57 mm at 90° and 52 mm on a rail on the Metabo UK sheet, on a 165 × 20 mm blade. The KT 18 bullets state up to 66 mm on a 165 mm blade. The KS 85 FS is the 2,000 W kit. Its capture names a 24-tooth carbide blade and does not state depth at 90°, so that figure stays unset.
What ships decides whether the sticker is the saw or the saw plus a rail. The KS 55 FS body includes a blade, a parallel guide and an extraction connector, not a rail. The set at about £274.69 names a case and FS 160, Metabo’s 1,600 mm guide rail. The KS 85 set names KFS 44, a cross-cut timing rail, plus a parallel stop. The KS 18 ships in a metaBOX 340 with a blade and a parallel guide, and the listing claims the shoe fits Metabo and several other rails.
Three typical situations, each with a recommendation from this comparison.
You already think in Festool or Makita rails and you want a corded Metabo shoe with the same groove, at a lower kit cost than a track saw. The KS 55 FS at about £147.99 is that body: 55 mm at 90° on the Metabo sheet, 4.7 from 227 reviews, and no rail in the box. Budget the rail if you do not own one.
You already run 18 V CAS packs and you want a cordless break on site. The KS 18 LTX 57 BL at about £159.95 is the hand saw for that: 57 mm at 90° on the Metabo UK sheet, brushless, rail-ready, body-only in a metaBOX 340. The amazon.co.uk file is 5.0 from only four reviews.
You want plunge entry and the 66 mm depth stated in the KT 18 bullets, and you already own CAS packs or you will price them. The KT 18 LTX 66 BL at about £359.00 is that plunge saw, body-only, with a dust bag and no rail. Reviews include warped-shoe reports, so check the base on arrival.
The top pick is the Metabo KS 55 FS, a corded body at about £147.99 with 4.7 from 227 amazon.co.uk reviews. Metabo states 55 mm at 90° on a 160 × 20 mm blade, and the box does not include a guide rail. Best value is the KS 55 FS set at about £274.69 if you want the FS 160 rail and the case in the same purchase, at 4.6 from 158 reviews. The KS 18 LTX 57 BL is the CAS hand saw at about £159.95 before batteries, with only four reviews. The KT 18 plunge saw is about £359.00 body-only, with warped-shoe reports. The KS 85 FS kit is about £613.79 with KFS 44 in the box and no star line in the capture.
KS 55 FS + FS 160
The FS 160 rail and the case are named in the title at about £274.69, so you are not buying the rail as a second order.
