Intro
For years, the oscillating multi-tool was one of the last holdouts of corded power — the thinking being that the constant, high-speed oscillation demanded more power than a battery could sustain for useful periods. That has changed. Modern brushless motors and high-capacity lithium-ion batteries have made cordless oscillating tools not just viable but genuinely compelling, especially for the kind of quick, varied tasks this tool type excels at. Think about how you actually use an oscillating multi-tool: you cut a door frame here, sand a corner there, scrape some adhesive in a third spot, all in different parts of the house or job site. With a corded tool, every move means managing the cable — unplugging, re-routing around furniture, and sometimes running an extension lead just for a 30-second cut. A cordless oscillating multi-tool eliminates all of that friction. You pick it up, walk to wherever the work is, and get the job done. For professionals moving between rooms on a renovation, and for DIYers tackling jobs around the home and garden, the freedom of battery power combined with the versatility of the oscillating form factor is a combination that genuinely changes how you work.
Generalities
When choosing a cordless oscillating multi-tool, the battery platform is the single most important consideration. The tool itself will last for years, but your investment in batteries and chargers — and the range of other tools that share them — determines the long-term value of your purchase. HIKOKI (formerly Hitachi Power Tools) offers a comprehensive 18-volt platform spanning professional-grade drills, saws, grinders, and garden equipment. A brushless motor is particularly valuable in an oscillating tool because it runs cooler, lasts longer, and extracts more runtime from each battery charge compared to brushed alternatives. The oscillation angle — typically between 1.6 and 3.6 degrees — directly affects how aggressively the tool cuts, with wider angles producing faster material removal.
In this review we examine HIKOKI's 18-volt brushless cordless oscillating multi-tool, sold as a bare unit for users already on the HIKOKI battery platform. We cover the brushless motor performance, the tool-free accessory change system, the notably wide oscillation angle, and how the tool handles cutting, sanding, and scraping across common materials and applications. We also address the cordless-specific considerations — battery life, compatible battery sizes, and whether a cordless oscillating tool makes sense for your type of work.
Description
The HIKOKI CV18DAW2Z is an 18-volt cordless oscillating multi-tool powered by a brushless motor that delivers variable-speed oscillation through an unusually wide 3.6-degree arc. To put that angle in perspective: most mid-range oscillating tools swing through 2.8 to 3.2 degrees, and many premium tools use narrower angles of 1.6 to 2.0 degrees. The 3.6-degree arc on the HIKOKI means each oscillation stroke covers more distance, resulting in faster cutting, more aggressive scraping, and noticeably quicker material removal — especially in softwood, plasterboard, PVC, and adhesives. The brushless motor is the latest generation design, offering higher efficiency, less internal wear, and longer service life than traditional brushed motors. It is sold as a bare tool — body only, no battery or charger — which makes it an attractive addition if you already own HIKOKI 18-volt batteries and a charger from other tools in the range.
The tool-free accessory change system on the CV18DAW2Z uses an improved locking lever mechanism. You simply flip the lever open, position the accessory, and snap the lever closed — the blade is secure and ready to use in under five seconds. The lever itself has a soft-close design, meaning it does not snap shut uncontrollably, which is a nice safety touch that also protects the mechanism from long-term wear. The tool body is compact and well balanced, measuring 32.7 by 8.7 by 12.2 centimetres and weighing just 1.2 kilograms as a bare unit — with a mid-sized battery attached, the total weight stays under 1.7 kilograms. This is noticeably lighter than most corded oscillating tools, and combined with the absence of a power cord dragging at your wrist, the CV18DAW2Z feels nimble and effortless to manoeuvre into tight corners, under cabinets, and overhead.
In everyday use, the wide oscillation angle is immediately apparent. Plunge cuts into plasterboard for electrical back boxes go faster than with narrower-angle tools, and scraping dried construction adhesive off sub-floors feels more aggressive and productive. The variable speed dial lets you match the oscillation rate to the task — lower speeds for controlled sanding and delicate scraping, maximum speed for fast cutting in softwood and plastics. HIKOKI has engineered the tool to minimise vibration and noise, and while it still vibrates — all oscillating tools do — the damping is effective and the tool remains comfortable for extended sessions. Battery life varies with the amp-hour rating of your pack: a 2.5 Ah battery gives roughly 25 to 30 minutes of mixed cutting and sanding, while a 5.0 Ah pack will see you through most of a working day of intermittent use.
As a bare-tool purchase, the CV18DAW2Z does not include batteries, a charger, or a comprehensive accessory kit — it ships with the tool body and the locking lever mechanism ready to accept standard oscillating tool accessories. HIKOKI offers a wide range of compatible blades, sanding pads, and scraping attachments, and the tool also accepts accessories from many other brands via the standard oscillating tool interface. This is a practical advantage: you are not locked into a single brand's accessory ecosystem and can shop around for the best value blades and attachments. The bare-tool format is ideal if you are already on the HIKOKI 18V platform — simply take a battery from your drill or circular saw and you are ready to work.
The HIKOKI CV18DAW2Z measures 32.7 by 8.7 by 12.2 centimetres and weighs 1.2 kilograms as a bare tool. It is a relatively new model with limited customer reviews so far, but HIKOKI's reputation as a professional-grade Japanese tool manufacturer — formerly Hitachi Power Tools — provides confidence in the engineering quality. The tool ranks at #72 in rotary tools on Amazon. At approximately €135 as a bare tool, it is priced competitively for a brushless cordless oscillating multi-tool from a respected professional brand. HIKOKI provides their standard manufacturer warranty, and the brushless motor's inherent durability means lower long-term maintenance compared to brushed alternatives.
Pros and cons
Pros
- 3.6-degree oscillation angle is among the widest available on any oscillating multi-tool — translates to noticeably faster cutting and more aggressive scraping than most competitors.
- Brushless motor delivers higher efficiency, longer runtime per battery charge, and extended service life compared to traditional brushed motors.
- Tool-free locking lever with soft-close mechanism allows accessory changes in under five seconds — fast, secure, and safer than levers that snap shut.
- Cordless freedom eliminates the hassle of managing power cables — pick up the tool and walk to wherever the work is, ideal for multi-room renovation projects.
- At 1.2 kilograms bare (under 1.7 kilograms with battery), it is one of the lightest oscillating tools available — effortless one-handed use and minimal fatigue overhead.
- Standard accessory interface accepts blades from HIKOKI and most other major brands — no proprietary lock-in to expensive consumables.
- Bare-tool format is cost-effective for existing HIKOKI 18V battery owners — no need to pay for batteries and charger you already own.
Cons
- Bare-tool only — no battery, charger, case, or accessories included, so first-time HIKOKI buyers face a significantly higher total cost to get started.
- Limited runtime on smaller batteries — a 2.5 Ah pack gives only 25 to 30 minutes of continuous mixed use, which may require multiple battery swaps on a full renovation day.
- No accessory kit included — you will need to purchase blades, sanding pads, and scraping attachments separately before using the tool for anything.
- The very wide 3.6-degree oscillation angle, while great for speed, can feel less controlled for ultra-precise delicate work compared to tools with narrower, smoother arcs.
- HIKOKI's 18V platform has a smaller market share than DeWalt, Makita, or Milwaukee — fewer retailers stock batteries and accessories, and the second-hand market is thinner.
Use cases
The HIKOKI CV18DAW2Z is ideal for existing HIKOKI 18V battery owners — professional tradespeople and serious DIYers — who want a lightweight cordless oscillating multi-tool with class-leading cutting speed for renovation, fitting, and maintenance tasks where cable-free convenience matters.
Multi-Room Renovation
When you are renovating several rooms, moving between cutting architraves in the hallway, scraping adhesive in the bathroom, and sanding filler in the bedroom, a corded tool means constant plugging and unplugging — or tripping over extension leads. The CV18DAW2Z lets you walk freely between rooms with the tool in hand, completing each task in seconds before moving on. With a 5.0 Ah battery, it runs long enough for a full morning of mixed tasks.
Kitchen and Bathroom Fitting
Fitting kitchens and bathrooms involves working inside cabinets, under worktops, and around pipework — exactly the tight spaces where a power cord snagging on every corner becomes infuriating. The CV18DAW2Z's compact dimensions and cordless design slip into these spaces effortlessly. The wide oscillation angle powers through worktop cutouts and plinth trimming fast, while the tool-free blade change keeps you productive when switching between tasks.
Outdoor and Garden Projects
Cutting a fence post flush, trimming decking boards, or sanding a garden bench far from the house is exactly where cordless freedom shines. The CV18DAW2Z handles these outdoor tasks without the need to run an extension lead across wet grass or through a doorway. The brushless motor's efficiency means the battery holds up well even when working away from the mains for an extended afternoon.
Quick Maintenance and Repairs
The real value of a cordless oscillating tool becomes apparent in those 30-second jobs: trimming a sticking door, cutting a notch in a shelf for a cable, or sanding a rough patch before touching up paint. With no cord to unwind and route, you grab the tool, do the job, and put it away — the total time is often less than it would take just to plug in a corded alternative. This grab-and-go convenience means small repairs actually get done instead of being postponed.
Professional Trade Work
For carpenters, joiners, and fitters who already use HIKOKI 18V drills and saws, adding this bare-tool oscillating multi-tool to the kit makes financial sense. The wide oscillation angle gives faster cutting than most competing models, and the light weight reduces fatigue during long days of fitting. The brushless motor's durability means the tool will withstand daily professional use without the brush-wear maintenance that brushed tools eventually require.
