Intro
The cordless circular saw has come a long way from the underpowered, short-runtime tools of a decade ago. Today's best cordless saws rival their corded counterparts in power, and they add something a cord can never offer: the freedom to cut anywhere. Framing a roof on scaffolding, breaking down sheet material in a timber yard with no accessible socket, or cross-cutting joists on a muddy building site — a quality cordless circular saw lets you work where the job is, not where the extension lead reaches. The key to this transformation is the brushless motor paired with modern lithium-ion battery technology. A brushless motor converts more of the battery's energy into blade rotation rather than wasting it as heat and friction, giving you more cuts per charge and a motor that does not wear out its brushes. Add an electric brake for safety, an LED cut-line light for accuracy, and a blower to keep sawdust off your mark, and you have a tool that genuinely earns its place as a primary saw rather than a backup for when you cannot run a cable.
Generalities
When choosing a cordless circular saw, blade diameter is the first decision. A 165 mm blade is the most common professional size — it gives about 66 mm of depth at 90 degrees, which is enough to cut through a 50 mm thick joist or a double layer of 18 mm plywood in a single pass. Motor type is critical: a brushless motor is strongly preferred for cordless tools because it delivers more runtime per amp-hour, runs cooler, and does not require brush replacement over the tool's lifetime. The battery platform determines your future tool options — Makita's 18 V LXT system is one of the broadest in the industry, with over 200 compatible tools. Cutting depth at 90 degrees and at 45 degrees tells you the thickest material the saw can handle, and the difference between those two numbers reflects how much depth you lose on bevel cuts. An electric brake that stops the blade within seconds of releasing the trigger is a genuine safety feature — it means you can set the saw down immediately rather than waiting for the blade to coast to a stop. A blower function that clears sawdust off the cut line is not a gimmick — it keeps your pencil mark visible as you cut, which improves accuracy and reduces the urge to lean over the spinning blade to see where you are going. Weight matters: a saw lighter than 4 kg is comfortable for all-day use and for one-handed operation when needed. Finally, check what is included — a bare tool costs less but requires existing batteries and charger; a kit with batteries included costs more upfront but gets you into the ecosystem.
This review examines a premium 18 V brushless 165 mm circular saw with electric brake, LED cut-line light, and integrated dust blower. We assess cutting power and runtime on a single battery charge, accuracy of the cut-line features, handling and ergonomics during extended framing work, and how it compares to a corded saw for professional daily use.
Description
The Makita DHS630Z is a cordless 165 mm circular saw powered by Makita's 18 V LXT lithium-ion battery platform. It features a brushless motor that delivers the equivalent of approximately 730 W of peak power output, spinning the blade at 3,100 RPM no-load speed. The 165 mm blade — a 24-tooth high-speed steel wood blade is included — has a 20 mm arbor bore. Maximum cutting depth is 66 mm at 90 degrees and 45 mm at a 45-degree bevel, giving single-pass capacity through standard 50 mm construction timber and 18 mm sheet material with room to spare. The bevel adjustment ranges from 0 to 45 degrees with positive stops at common angles. This is a bare-tool purchase: it ships without battery or charger and is intended for users already invested in Makita's 18 V LXT battery ecosystem.
Three features set the DHS630Z apart from entry-level cordless circular saws. First, the electric motor brake stops the blade within approximately two seconds of releasing the trigger — a significant safety improvement that lets you set the saw down immediately after completing a cut rather than holding it in the air while the blade spins down. Second, the integrated LED work light projects a bright beam onto the cut line ahead of the blade, illuminating the pencil mark even in poor light conditions like the inside of a roof space or under a deck. Third, the blower function directs a stream of air across the front of the base plate, clearing sawdust and chips off the cut line so you can see exactly where the blade will enter the material. These are features you notice most when you go back to using a saw without them.
In daily use, the DHS630Z feels balanced and responsive. At 3.4 kg without a battery (approximately 4 kg with a 5 Ah pack fitted), it is light enough for prolonged one-handed operation when needed — cutting rafters in situ, trimming the bottom of a hung door, or making vertical cuts on wall-mounted sheet material. The base plate is a rigid pressed design with a fine-adjustment mechanism for the parallel guide, and the blade sits on the left side of the motor — a preference shared by many right-handed users because it keeps the cut line visible without leaning over the saw. The rear dust extraction port connects to a vacuum hose for cleaner indoor cutting, and the blower can be directed or partially blocked depending on the work environment. Runtime on a 5 Ah battery is approximately 40–60 cross-cuts through 50 mm pine, depending on feed rate and wood density — easily enough for a morning of framing between charges.
As a bare tool, the box contains the saw body, a 165 mm 24-tooth wood blade, a parallel guide for repeat-width rip cuts, and a hex key for blade changes. No battery, charger, or carry case is included. The saw is compatible with all Makita 18 V LXT batteries from compact 1.5 Ah packs for light work to 6 Ah high-capacity packs for all-day use, and performance scales noticeably with battery capacity — a 5 Ah or 6 Ah pack provides noticeably more torque and sustained RPM under load than a 3 Ah compact. The blade arbor has a spindle lock for one-wrench blade changes. Makita offers a 2-year manufacturer warranty, and the saw is manufactured in France — a mark of Makita's commitment to local production for the European market.
The DHS630Z measures compactly for a 165 mm saw and weighs 3.4 kg bare. Customer satisfaction is exceptional: 4.7 out of 5 stars from 252 reviews, ranking #134 in Circular Saws on Amazon.fr. At around €240 for the bare tool, it sits in the premium tier of 165 mm cordless saws — above the entry-level offerings but justified by the brushless motor, electric brake, LED, blower, and the quality of the Makita LXT ecosystem. For professional carpenters, framers, kitchen fitters, and serious renovators who already run Makita 18 V batteries, this saw is a natural addition that will quickly become the most-reached-for cutting tool in the van.
Pros and cons
Pros
- Brushless motor delivers efficient, fade-free power — equivalent to a 730 W corded saw, with longer runtime and no brush wear to manage over the tool's life.
- Electric motor brake stops the blade in approximately 2 seconds — a genuine safety upgrade that lets you set the saw down immediately after every cut.
- Integrated LED cut-line light and dust blower work together — the light illuminates the pencil mark, and the blower clears chips away so you see exactly where the blade will enter.
- 66 mm depth of cut at 90° handles standard construction timber in one pass — 50 mm joists, 18 mm sheet material, and even 63 mm CLS framing stock.
- At 3.4 kg bare, it is light enough for comfortable one-handed use — trimming door bottoms, cutting installed boards vertically, and working in awkward positions.
- Compatible with the entire Makita 18 V LXT ecosystem — 200+ tools sharing the same batteries, so a single battery investment fuels your whole cordless kit.
- 4.7 out of 5 stars from 252 reviews — near-universal praise for power, build quality, and the usefulness of the brake/LED/blower combination.
Cons
- Bare tool only — no battery, charger, or carry case. The effective price jumps to over €400 for a first-time Makita user who also needs to buy batteries and a charger.
- Blade sits on the left side of the motor — preferred by right-handed users who sight down the right side of the saw, but can feel awkward for left-handed operators accustomed to blade-right designs.
- No brushless motor speed compensation under extreme load — very heavy feed pressure in dense hardwood can cause a noticeable RPM drop, though this is common across cordless saws in this class.
- Rear dust extraction port is effective but the blower and extraction somewhat work against each other — for best dust collection, connect a vacuum and accept slightly less effective cut-line clearing.
- At €240 for the bare tool, it is priced at a premium — entry-level corded 165 mm saws cost a fraction of this, though they lack the brushless motor, brake, cordless freedom, and refinement.
Use cases
This premium cordless 165 mm circular saw is ideal for professional carpenters, framers, kitchen fitters, and serious renovators on the Makita 18 V LXT battery platform who want a primary-use cordless saw with all the refinement features of a top-tier corded model.
Timber Framing and First-Fix Carpentry
Cross-cutting 50 × 100 mm and 50 × 150 mm joists, studs, and rafters to length on site is the bread-and-butter application. The 66 mm depth of cut handles standard framing stock in one pass, the blower keeps the cut line visible in bright sunlight, and a 5 Ah battery lasts through dozens of cuts between charges.
Sheet Material Breakdown and Kitchen Fitting
Cutting full 18 mm plywood and MDF sheets to size for cabinetry, shelving, and built-in furniture. The fine-adjustment parallel guide gives repeatable rip widths, the LED light keeps the cut accurate in workshop conditions, and the rear dust port connected to a vacuum dramatically reduces airborne MDF dust.
Roof Work and Scaffold Cutting
Cutting rafter tails, trimming fascia boards, and modifying roof timbers from a scaffold or ladder platform — where cordless freedom is not a convenience but a safety necessity. No extension lead to trip over, no cable snagging on roof tiles or scaffolding, and the electric brake lets you set the saw down safely after each cut while balanced at height.
Decking and Landscaping Timber Work
Building decks and outdoor structures involves cutting treated timber in all weathers, often far from mains power. The saw handles wet, heavy treated pine without complaint, and the blower is especially useful in outdoor conditions where wind-blown sawdust can quickly obscure a pencil line.
Renovation and Second-Fix Carpentry
Trimming door bottoms to clear new flooring, cutting skirting and architrave to length, and modifying built-in furniture during renovation work. The light weight and one-handed controllability make the saw nimble enough for precise trim work, and cordless operation means no cable damage in finished rooms.
