On a renovation site, when switching from cutting pine paneling to an oak beam without being able to change machines, the Makita DHS680Z shows what sets it apart from competing cordless circular saws: a torque controller that adjusts the speed to the material in real-time.
This 18 V LXT brushless motor circular saw runs at 5,000 RPM when unloaded, weighs between 3.0 and 3.3 kg including the battery, and offers a cutting depth of 57 mm at 90°. Sold in a solo version (without battery or charger), it targets both professionals and demanding DIYers who already own Makita LXT batteries.
Brushless motor and ADT technology: what it changes on the job site
The brushless motor of the DHS680Z eliminates the mechanical wear of brushes, extending the machine’s lifespan. In practice, it mainly improves cutting consistency: no drop in power during the cut, even in hardwood.
The ADT (Automatic Torque Drive) technology automatically adjusts the torque based on the resistance encountered. When the blade hits a knot in oak or beech, the controller increases the torque without the rotational speed collapsing. On soft conifers, the machine automatically reduces the power consumption, which preserves battery life over a full workday.
This adaptive behavior makes a significant difference compared to cordless saws with conventional motors, where the user must modulate pressure to avoid stalling. There is a guide on the Makita DHS680Z that details these mechanisms for those who want to delve deeper into the technical aspects.
Cutting capacity and 165 mm blade: the real limits
The advertised cutting depth is 57 mm at 90°, 41 mm at 45°, and 37 mm at 50°. On paper, this is sufficient for most common secondary work: baseboards, battens, plywood panels, decking boards.
However, for beams of 60 mm or more, you hit the physical limit of the 165 mm blade. You then need to flip the piece to finish the cut, which affects precision. For sections over 55 mm, a corded circular saw or a 190 mm model is preferable.
The bevel range goes from 0 to 50° to the left. The adjustment is progressive, with pre-positioned notches at 22.5° and 45°. On repetitive angled cuts (like installing corner baseboards), the lock holds well and does not slip under vibration.
Choosing the blade based on materials
The original blade is suitable for soft solid wood and panels. For more demanding materials, you adapt the equipment:
- Hardwoods (oak, beech, ash): a carbide blade with alternating teeth and a high tooth count reduces splintering and requires less effort from the motor
- Melamine or laminate panels: a trapezoidal tooth blade limits chipping on the visible face, provided you cut with the decorative side down
- Softwoods and standard plywood: the original blade is sufficient, but regular replacement maintains cutting quality and prevents overloading the motor
Compatibility with LXT 18 V batteries and Makita ecosystem
The DHS680Z works with all Makita LXT 18 V batteries, from 1.5 Ah to 6.0 Ah. This point is crucial for those who already own Makita equipment: the LXT ecosystem includes over 300 compatible tools, allowing for shared batteries and chargers between drills, screwdrivers, job site vacuums, and circular saws.
However, the batteries from the 40 V max XGT range are not compatible. The separation between the two platforms is strict, with no official adapter. If you plan to switch to 40 V Makita in the future, the DHS680Z will not follow in this transition.
With a 5.0 Ah battery, you get enough runtime for several dozen cuts in softwood before needing to recharge. Feedback varies on this point depending on the material density and cutting depth, but in real job site conditions, working with two batteries in rotation avoids downtime.
Safety and ergonomics in the work situation
The soft start prevents torque kickback when starting up. On plunge cuts or starting cuts near an edge, this behavior reduces the risk of blade deviation.
The electric brake stops the blade in less than two seconds after releasing the trigger. Combined with the safety button that prevents accidental activation, this creates a coherent system for use on scaffolding or at height.
- The built-in LED lights up the cutting line, compensating for low light in attics or under slopes
- The rubber-coated handle absorbs some vibrations and maintains grip even with work gloves
- The compact dimensions (350 x 170 x 238 mm) allow for work in tight spaces, between joists or in a technical closet
Pricing position of the Makita DHS680Z and relevance of the solo purchase
The DHS680Z is in the high-end segment of cordless circular saws at 18 V. In the machine-only version, observed prices range from €190 to €230. Complete packs with two batteries and a charger are around €400.
The solo purchase is only justified if you already own at least one LXT 18 V battery and a charger. Buying the machine alone and then batteries and charger separately is more expensive than a pack. For a first Makita setup, the pack remains the best economic option.
Against competing models in the same price range, the DHS680Z stands out for its brushless motor and ADT technology, two features absent on most entry-level cordless circular saws. The extra cost is justified if you regularly cut hardwoods or if you are making multiple cuts in a full day, where battery life and torque management make a real difference.
