Cordless circular saw buying guide

Updated: 21 October 2026

You are looking at an amazon.co.uk price and it reads as if the saw is ready to cut. Often it is only the body. A cordless circular saw buying guide has to split blade size from battery platform before the star rating gets a vote. On the nine listings compared here on 19 October 2026, the shelf runs from £47.99 to £179.99, and two of the names people recognise are bare tools. The [cordless circular saw comparison](/hub/power-saws/cordless-circular-saw) holds the table, the scores and the review counts. A rail plunge saw is a different tool on the [circular saw vs plunge saw](/hub/power-saws/cordless-circular-saw/sub/cordless-circular-saw-vs-plunge-saw) page. Peter F. compared the listings and public UK guidance. There was no lab test. A qualifying purchase can earn a commission at no extra cost to you.

Body only or a kit

The figure on the card is often the saw alone. The Ryobi R18CSP-0 is listed at £76.95 with an 18-tooth TCT blade, a hex key and a side fence, and the title excludes the battery and the charger. The Bosch Professional 06016A2101 is listed at £171 in an L-BOXX with a parallel guide and a wood blade, and the listing says two lithium-ion batteries are required. Neither price cuts timber on the day it arrives unless the matching packs are already on your shelf. The Dong Cheng DCMY165S at £82.99 includes a 4.0 Ah pack, a charger, a bag, a dust adaptor and two blades, on Dong Cheng's own 20 V system. The TEENO 165 mm listing at £59.99 and the Galax Pro at £56.09 also arrive as kits, though the TEENO title, bullets and components line do not agree on one battery or two. BuildWiz's rule of thumb, from other retailers, puts a cordless body at about £90–£160 before batteries. Those bands are not these ASINs.

Blade diameter before brand

Diameter decides the class of cut before the logo does. This set runs from a 76 mm TEENO mini, through a 115 mm Galax and a 125 mm Keleef, to a 150 mm Ryobi, several 165 mm saws, and a 190 mm Worx that states no depth at all. The Ryobi's 150 mm blade is quoted at 45 mm at 90° and 32 mm at 45°. It does not clear a 47 mm face in one pass. TEENO states 54 mm at 90° and 38 mm at 45°. Dong Cheng states 59 mm at 0°, 43 mm at 45° and 39 mm at 50°. Bosch's bullets say cuts up to 57 mm and do not split a 45° depth on the amazon.co.uk row. If you already know the thickness, take it to the depth of cut page. Ryobi and Galax state a 10 mm bore. Bosch's included blade is 165 mm with a 20 mm hole. A 20 mm blade will not sit on a 10 mm spindle.

One battery family

A second charger is the expensive mistake. Ryobi is 18 V ONE+. If those packs are already in the house, the £76.95 body is the listing that uses them, and a Dong Cheng 20 V pack will not click on. Bosch is 18 V Professional, and the listing says two batteries are required. The rail is not in the box. The TEENO mini highlight claims Makita compatibility. The battery row on the same listing says two AAAA batteries. Do not plan a Makita slide-pack around that line. If you own no platform and you want 165 mm with a 4.0 Ah pack under £90, Dong Cheng is the kit in this set that states that combination. Who each listing is for is on the best cordless circular saw page.

What the listing rows get wrong

Several rows in this set disagree with the line above them. Bosch's speed cell prints 3.4 RPM, which is not a usable no-load speed for a circular saw. Worx's highlight lists a 4.0 Ah PowerShare battery and a charger, and the components line says battery only. TEENO's title says one battery, the bullets say two 4.0 Ah packs, and the components line only says Battery. Keleef's title says 21 V cordless and also ends in the word Corded. Dong Cheng prints 840 W and Worx prints 520 W. Those cells are not a measured comparison of cutting power. Keleef is 5.0 from four amazon.co.uk reviews. Ryobi is 4.6 from 981. Read the scope line before the highlight. If they disagree, the Consumer Rights Act 2015 covers a saw that is not as described when it arrives.

Common questions

Should you buy body only or a kit with a battery?
Buy body only when you already own the matching packs. The Ryobi at £76.95 and the Bosch at £171 are both bare on amazon.co.uk, so the first cut waits on a battery you supply. Buy a kit when you own nothing in that voltage. The Dong Cheng at £82.99 includes a 4.0 Ah pack and a charger. A cheaper kit can still disagree with itself about how many batteries are in the box, so read the components line, not only the title.
Is 150 mm enough, or do you need 165 mm?
The Ryobi's 150 mm blade is stated at 45 mm at 90° and 32 mm at 45°, which covers sheet and board under that figure. It does not clear a 47 mm face in one pass. A 165 mm listing in this set is the class that quotes 54 mm to 59 mm at 90°, and each figure is the seller's bullet, not a cut we measured. If your thickest piece is over 45 mm, start with 165 mm and then check the depth at the bevel you will use.
Can a Galax or Keleef 115–125 mm saw do studwork?
No, not as a one-pass stud saw. The Galax is 115 mm and states 42.8 mm at 90°, and UK reviews describe it cutting out every few inches on 20 mm wood, laminate and chipboard. The Keleef is 125 mm with a title claim of 50 mm, from four reviews. Use either for thin sheet and offcuts. Move up a diameter when the timber is thicker than the stated depth, or when the piece is structural and a joiner should take the cut.
Does the Bosch £171 price include batteries and a rail?
No. The £171 listing is the body in an L-BOXX, with a parallel guide, and it says two batteries are required. The bullets say the saw is guide-rail compatible, and the scope line does not include a rail. You need packs you already own, and a rail you buy separately, before that price is a working setup. It is still a circular saw that starts at an edge, not a plunge saw.
Will a Ryobi ONE+ battery fit the Dong Cheng?
No. The Ryobi is 18 V ONE+. The Dong Cheng kit uses Dong Cheng's own 20 V pack. They do not swap. Buying the Dong Cheng because it sits close to the Ryobi's price starts a second charger and a second battery shape. Stay on ONE+ if those packs are already charged on the shelf.
What does a 10 mm bore change when you buy spare blades?
Ryobi and Galax state a 10 mm bore, so a spare blade has to match that hole as well as the diameter. Bosch's included blade is 165 mm with a 20 mm hole, which will not fit a 10 mm arbor. Check both numbers on the packet. A blade that is the right width and the wrong hole is not a saving, and it should not be forced on with a bush the listing never names.
