The best Worx circular saws, compared.
Top pick: WORX WX530.9 ExacTrack – Highest score: 4.7 from 321 reviews, ExacTrack guidance in the bullets, and a brake named in special features. Best value: WORX WX531 120 mm kit – Only complete kit in the set: £99.00 with a 2.0 Ah battery, charger, case and three blades, at 4.5 from 350 reviews. Updated October 2026.
Choosing a Worx circular saw on amazon.co.uk means separating five listings that share a brand and not much else. One is a bare compact saw priced 35p higher. One is a bare body whose title says a blade. Two WX520.9 pages both carry that code and do not match. This comparison uses those amazon.co.uk listings, the star lines and the public Worx UK pages. Compact 120 mm saws suit stock inside that 41 mm. The order of checks, and the listing traps, is set out in the [Worx circular saw buying guide](/hub/power-saws/worx-circular-saw/sub/worx-circular-saw-buying-guide). A Worx circular saw is a cordless hand-held saw for straight cuts, sold on amazon.co.uk as a cordless saw. The compact pair is the WX531 kit and the bare WX531.9. Battery in the box is the first check.

Question 1 of 2
Do you already own a Worx PowerShare pack?
The WORX WX530.9 listing at £101.99 is the ExacTrack body, and it holds the highest star line in this set: 4.7 from 321 reviews, with the first 50 saved bodies marked United Kingdom. The item type says EXACTRACK Cordless Circular Saw and the best-sellers line places it in Circular Saws, while the title says a TCT/HSS saw blade, so the page is a saw and not a spare blade. The highlight says tool only, and the included line is the WX530.9, with no battery and no rail. Special features name a brake, and UK reviews describe the blade stopping when the trigger is released. Reviewers who have learned the rack like the straight cut, and a minority call the saw underpowered in thicker sheet and say you still have to watch the blade. Amazon states no depth. uk.worx.com states 55 mm for this body, and that figure is not an Amazon field. The blade-length field says 165 mm, the bevel bullets say 50 degrees, and the speed field says 6000 RPM. Dimensions of 14.1 × 8 × 8.5 cm sit oddly against a weight of 3.06 kg, and both lines stay on the listing as written. It is the top pick when you already have a pack and you will clamp your own straight edge. It is the wrong first tool if you needed a charger in the box.
Pros
Cons
Best for: You already own a PowerShare pack and want a straight rip against an edge you clamp yourself.
Less suitable: A first saw with no battery, or anyone who read the title as a spare blade.
Specifications
Common questions
Is this listing a spare blade?
The title says a TCT/HSS saw blade. The item type says EXACTRACK Cordless Circular Saw, and the best-sellers line places it in Circular Saws. The page is the saw, not a blade guide.
Is a battery included?
No. The highlight says tool only, and the included line is the WX530.9. A rail is not in that line either.
Does the listing name a brake?
Yes. Special features say Brake, and the bullets say a brake function. Amazon states no cutting depth on this page.
This WX520.9 page is £127.49 and shows 4.6 from 69 reviews on amazon.co.uk, but the 14 review bodies saved with the raw file are marked Italy, Germany and Spain, so that star line is not British opinion. The included line is one circular saw, and a battery is not stated. The blade-length field says 185 mm and the shape field says Rectangular, the speed field says 5200 RPM, and the wattage field says 900 watts. The country of origin is Turkey and the manufacturer field says Positec. The hero image URL matches the other WX520.9 listing, while the fields do not: that other page states 6100 RPM, an included 190 mm blade, a parallel guide and China as the origin. The cutting-angle field here says 90 degrees and there is no bevel figure. Weight is 2.9 kg, and the warranty line mentions EU spare-part availability of five years rather than the three-year registration line on the other Worx pages. Treat this ASIN as a thin, conflicting listing, not as a cheaper twin of the Nitro body.
Pros
Cons
Best for: You have already opened both WX520.9 pages and you are checking this ASIN's own fields before you buy.
Less suitable: Anyone who would treat 4.6 from 69, or the non-UK review text, as a reason to prefer it over the Nitro listing.
Specifications
Common questions
Are the saved reviews from the United Kingdom?
No. The 14 review bodies in the raw are marked Italy, Germany and Spain. The star line on amazon.co.uk is still 4.6 from 69.
What does the included line name?
1 x circular saw. A battery is not stated. Bullets do not say a battery is included.
Is this the same page as the £160.75 WX520.9?
No. The model number matches and the hero image URL matches B08BCKXP7K, but the fields differ, including 5200 RPM, blade shape Rectangular, origin Turkey and manufacturer Positec.
The WORX WX531 kit is the only listing in this set whose included line names a battery, a charger, a case and three blades, at £99.00 on amazon.co.uk on 16 October 2026. A bullet says the pack is 2.0 Ah, and the same bullets state 41 mm at 90 degrees and 29.5 mm at 45 degrees, with a bevel field of 46 degrees. Across 350 reviews the star line is 4.5. Reviewers treat it as a light DIY saw, and they also say the blade has to come off before the case will shut, with a missing blade or hex key turning up often enough to matter under the 30-day right to reject. The speed field says 6900 RPM while a bullet says 6,100 RPM, and the wattage field of 531 watts copies the model number, so neither figure is a motor rating you should quote. Amazon's special-features line does not name a brake. At this price, with a pack in the box, it is the best value when 41 mm will go through the sheet. It is the wrong saw if the timber is closer to 47 mm, which a UK review on the bare sibling already found too thick.
Pros
Cons
Best for: You have no Worx pack yet and the stock is inside the stated 41 mm at 90 degrees.
Less suitable: Timber a UK review put near 47 mm, or a straight rip that needs the ExacTrack rack.
Specifications
Common questions
Does this listing include a battery?
Yes. The included line names a battery, a charger, a case and three blades. A bullet says the battery is 2.0 Ah.
What depth do the bullets state?
41 mm at 90 degrees and 29.5 mm at 45 degrees. The blade-length field says 46 mm, while the title says 120 mm.
Does the special-features line name a brake?
No. It names brushless and depth adjustment. The speed field says 6900 RPM and a bullet says 6,100 RPM.
The WORX WX531.9 is the compact body sold bare at £99.35, which is 35p more than the kit whose included line names a battery. This included line is a 24-tooth TCT blade, a ceramic tile blade, an HCS metal blade, a hex key and a vacuum adaptor, and it does not name a battery, a charger or a case. amazon.co.uk shows 4.4 from 159 reviews. Of the 42 review bodies saved with this listing, the countries stated are the United Kingdom except one from Ireland. Some of those UK reviews report sheet, MDF and 18 mm ply with a 4 Ah pack, while others report cut-outs on 9 mm to 12 mm ply, and one put stock near 47 mm past what the saw would do. The item type states 41 mm, the title says 120 mm, and the blade-length field says 41 mm, so the blade diameter and the depth are easy to swap. A bullet says 1.71 kg without a battery against a weight field of 1.85 kg, and the wattage field of 200 watts is not a figure to quote as motor power. Next to the £99.00 kit, this bare listing is the worse of the two prices unless you already own PowerShare packs and you specifically want the named tile and metal blades.
Pros
Cons
Best for: You already own a PowerShare pack and want the compact body plus the tile and metal blades named on this page.
Less suitable: A first Worx tool with no battery, or timber thicker than the stated 41 mm.
Specifications
Common questions
Is a battery in the box?
No. The included line names three blades, a hex key, a vacuum adaptor and the WX531.9. It does not name a battery, charger or case.
How does this price sit next to the kit listing?
This bare saw is £99.35. The WX531 kit listing is £99.00 and its included line names a battery.
What do the saved reviews say about ply?
Some report sheet, MDF and 18 mm ply with a 4 Ah pack. Others report cut-outs on 9 mm to 12 mm ply. That is a pattern in the saved bodies, not a counted failure rate.
The WORX WX520.9 Nitro body is £160.75 on amazon.co.uk, tool only, with 4.4 from 56 reviews. The highlight says the battery and charger are sold separately. The included line names a 190 mm TCT blade, a hex key, a parallel guide, a vacuum adaptor and the saw. The item type states 65 mm at 90 degrees and a bevel of 0 to 57 degrees, while the cutting-angle field says 90 degrees and the blade-length field says 185 mm. The wattage field of 520.9 watts copies the model number, and the power-source field says both battery powered and corded electric, which this bare cordless listing does not reconcile. Of 14 saved review bodies, all but one are marked United Kingdom. Those reviewers report stalls when the cut is pushed, and some say it is not a trade saw. That is a pattern in a small sample, not a failure rate. Weight is listed at 3.8 kg. Buy it when the stock is thicker than the compact saw's 41 mm and you have already budgeted a PowerShare pack. Skip it as a first Worx tool, and do not quote the manufacturer kit page's 64 mm line or 67.5 mm table as if they were this Amazon field.
Pros
Cons
Best for: You already own a PowerShare pack and the timber is thicker than the compact saw's stated 41 mm.
Less suitable: A first tool with no battery, or anyone who needs a trade saw on the strength of these reviews.
Specifications
Common questions
Is a battery included?
No. The highlight says the battery and charger are sold separately. The included line names a 190 mm TCT blade, a hex key, a parallel guide, a vacuum adaptor and the saw.
What depth does the item type state?
65 mm at 90 degrees. The blade-length field says 185 mm, while the title and the included blade say 190 mm. The cutting-angle field says 90 degrees and the item type also says bevel 0 to 57 degrees.
What do the saved UK reviews say about stalling?
Reviewers report stalls when the cut is pushed, and some say it is not a trade saw. That is a pattern in 14 bodies, not a failure rate.
Five amazon.co.uk listings are on this page. The 0–100 score is an editorial reading of those listings and the public Worx UK pages, not a laboratory cut. Amazon stars and review counts stay visible beside the score. The highest final score is the top pick. The strongest equipment-for-price package is the best value, and it does not have to be the highest-scoring saw.
Amazon rating and evidence depth
35%The star rating contributes up to 25 points. Review count and the amount of usable UK review evidence contribute up to 10. A very small sample, or no usable United Kingdom review bodies, is marked down.
Practical review sentiment
25%Repeated UK reports on cut quality, control, runtime and reliability. Isolated comments carry less weight than a pattern that turns up across the saved bodies.
Equipment and capability
25%Stated cutting depth, bevel adjustment, blade and guide provision, a brake or spindle lock, and useful dust-control accessories. A missing depth or battery line is marked down.
Value
15%The recorded GBP price is set against the included battery, charger, blades, case and guides. A bare-tool price that sits poorly beside a similarly priced kit is marked down. No current-price claim is made beyond the saved listing.
Separate these five amazon.co.uk listings by the battery in the box, the depth you can cite, and whether the title matches the item type. Prices below are the Amazon figures of 16 October 2026, from £99.00 to £160.75. uk.worx.com was higher the same day, and those shop prices do not replace the Amazon figures. This page is not a lab test.
A Worx circular saw in this comparison is a cordless hand-held saw for straight cuts, sold on amazon.co.uk as a PowerShare tool. It is not a bench saw. The WX530.9 page is not a spare blade, even though the title says one. Five listings stay in the set. The compact pair is the WX531 kit and the WX531.9 bare saw. The ExacTrack body is the WX530.9. Two further pages both say WX520.9 and must not be merged. Battery in the box is the first check.
The title says a TCT/HSS saw blade. The item type says an ExacTrack cordless circular saw, and the rank sits in Circular Saws. The included line is the WX530.9 only. There is no rail in the box.
The WX531 kit is £99.00 and names a 2.0 Ah battery, a charger, a case and three blades. The bare WX531.9 is 35p more and names none of those. On these two prices the bare saw is the worse deal.
Fields of 531, 200 and 520.9 watts copy the model number. The thin WX520.9 page prints 900 watts, which should not be set beside that 520.9 figure as a measured motor. Quote the clash, not a ranking.
Only one listing in this set names a battery. That is the WX531 kit at £99.00 on amazon.co.uk. The included line names a battery, a charger, a case and three blades, and a bullet says the pack is 2.0 Ah. The star line is 4.5 from 350 reviews. The bare WX531.9 is £99.35, which is 35p more, and its included line does not name a battery, a charger or a case. It does name a 24-tooth TCT blade, a ceramic tile blade, an HCS metal blade, a hex key and a vacuum adaptor.
Quote a depth only when the listing states it. Kit bullets say 41 mm at 90 degrees and 29.5 mm at 45 degrees. The bare item type says 41 mm. The Nitro item type says 65 mm at 90 degrees and a bevel of 0 to 57 degrees, while its cutting-angle field says 90 degrees and its blade-length field says 185 mm against a 190 mm blade in the included line. The WX530.9 Amazon page states no depth. uk.worx.com states 55 mm for that body.
Three typical situations, each with a recommendation from this comparison.
You have no PowerShare battery and the stock sits inside 41 mm. The WX531 kit is £99.00, rated 4.5 from 350 reviews. The included line names a 2.0 Ah battery, a charger, a case and three blades. The bullets state 41 mm at 90 degrees and 29.5 mm at 45 degrees. A UK review put stock near 47 mm already past this family.
You already own PowerShare packs and you want a straight edge you clamp yourself. The WX530.9 ExacTrack body is £101.99, rated 4.7 from 321 reviews. Special features name a brake. The included line is the saw only, with no battery and no rail. Amazon states no cutting depth.
The compact bullets stop at 41 mm. The Nitro WX520.9 body, at £160.75, is the listing whose item type states 65 mm at 90 degrees. It is rated 4.4 from 56 reviews, and the battery and charger are sold separately. UK reviews in a small sample report stalls when the cut is pushed, and some say it is not a trade saw.
For a straight rip when you already own a PowerShare pack, the top pick is the WORX WX530.9 ExacTrack at £101.99, rated 4.7 from 321 reviews, with a brake named and no battery in the box. For a first Worx saw when 41 mm will go through the sheet, the best value is the WX531 kit at £99.00, rated 4.5 from 350 reviews, because it is the only listing here that names a 2.0 Ah battery, a charger, a case and three blades. The bare WX531.9 at £99.35 does not include that pack. The Nitro body is the one to open when the timber is thicker than 41 mm and a separate pack is already in the budget.
WORX WX530.9 ExacTrack
Highest score: 4.7 from 321 reviews, ExacTrack guidance in the bullets, and a brake named in special features.
WORX WX531 120 mm kit
Only complete kit in the set: £99.00 with a 2.0 Ah battery, charger, case and three blades, at 4.5 from 350 reviews.
