IRONFIST Oscillating Tools Review

Building a collection of cordless power tools is one of the smartest investments a DIYer or tradesperson can make, but it comes with a hidden cost: once you commit to a battery platform, every new tool you add carries the brand's price tag. An 18-volt oscillating multi-tool from one of the major manufacturers can easily cost over €150 as a bare unit, and for someone who only needs this type of tool occasionally, that is a steep threshold. A growing category of third-party tools has emerged to fill exactly this gap — tools engineered to work with the batteries you already own, from brands like Milwaukee, DeWalt, Makita, and Bosch, but sold at a fraction of the price of the original manufacturer's equivalent. These tools make it possible to add capability to your kit without breaking the bank, turning that drawer full of batteries into a power source for an expanding range of useful tools. For the occasional user who only reaches for an oscillating multi-tool a few times a year — to trim a door frame, scrape some paint, or sand a corner before redecorating — a compatible third-party tool can be the difference between getting the job done comfortably and putting it off because the branded tool is too expensive to justify.

Third-party battery-compatible tools occupy an interesting position in the market. They are not competing directly with the premium brands on build quality or longevity — those are battles they would lose. Instead, they compete on value: can they deliver adequate performance for occasional use at a price low enough to make them an impulse purchase for existing battery owners? The key considerations are whether the battery connection is secure and reliable, whether the motor provides enough power for typical tasks, and whether the tool comes with enough accessories to be useful straight out of the box. IRONFIST is a brand that has built a range of tools specifically designed for cross-compatibility with major battery platforms, focusing on the types of tools that DIYers need occasionally rather than daily.

In this review we look at a cordless brushless oscillating multi-tool from IRONFIST that is compatible with Milwaukee M18 18-volt batteries. We cover the 6-speed motor performance, the build quality and ergonomics, the 23-piece accessory kit included in the box, and how it handles typical DIY cutting, sanding, and scraping tasks. We also honestly address where the compromises of a budget third-party tool show up, so Milwaukee battery owners can decide whether this represents genuine value or a false economy.

The IRONFIST oscillating multi-tool is powered by a brushless motor that delivers six selectable speed settings ranging from 8,000 to 20,500 oscillations per minute. It is designed to accept Milwaukee M18 18-volt lithium-ion batteries, covering the full range of M18 packs from compact 1.5 Ah units through to high-capacity 5.0 Ah and above. The brushless motor is a pleasant surprise at this price point — brushless motors are more efficient, run cooler, and last longer than brushed alternatives, which matters for a tool that vibrates constantly during use. The battery interface is a physical slide-on connection moulded into the tool body, mimicking the Milwaukee M18 mounting geometry. It is not a licensed or official Milwaukee product, but in practice the battery clicks in securely and makes solid electrical contact.

The design is functional and straightforward. The tool body is compact and relatively light, with a rubberised grip section that provides decent hold during use. The six-speed dial is positioned on the top of the body within easy thumb reach, letting you adjust the oscillation rate without taking your hand off the grip. The on-off switch is a simple slide mechanism rather than a variable-speed trigger — you set the speed on the dial, slide the switch on, and the tool runs at that constant rate. The blade change system uses a standard bolt-and-hex-key mechanism with the hex key stored in a slot on the tool body, which is more convenient than budget tools that require you to find your own key. The tool accepts standard oscillating tool accessories from most brands via the universal mounting interface.

In use, the IRONFIST handles typical DIY oscillating tool tasks competently. The six speed settings give adequate control — lower speeds for sanding painted surfaces without burning through, mid-range for scraping adhesive, and maximum speed for cutting softwood and plasterboard. The motor has enough power for these common tasks, though it will not match the sustained cutting speed of a premium-branded tool when you are working through dense hardwood or thick metal. Vibration and noise levels are on the higher side compared to professional tools — this is one area where the price difference is most apparent — and extended continuous use beyond 15 to 20 minutes becomes tiring. For the kind of short, task-focused work this tool is aimed at, however, the performance is perfectly adequate.

The 23-piece accessory kit included in the box is genuinely generous for a tool at this price. You get three blades for cutting wood, metal, and plastic; two flexible stainless steel scrapers for removing adhesive, paint, and sealant; one semi-circular saw blade for plunge cuts and curved work; a sanding plate; and 15 sanding papers. A side handle is also included for two-handed control during heavier cutting. This is enough to start most common DIY renovation tasks immediately — flush-cutting, scraping, and sanding — without needing to buy additional accessories. The blades are basic quality and will wear faster than premium alternatives, but standard replacements are widely available and affordable.

The IRONFIST oscillating tool does not yet have customer reviews, being a relatively new product. At approximately €55, it is one of the most affordable ways to add a cordless oscillating multi-tool to your kit if you already own Milwaukee M18 batteries. There is no battery or charger included, and no storage case — the tool and accessories ship in standard packaging. The manufacturer provides a user manual, though the French translation is not guaranteed. For Milwaukee battery owners who use an oscillating tool a handful of times a year, this represents a pragmatic way to access the capability without the €150-plus investment a branded Milwaukee tool would require. For daily professional use, the premium original is still the right choice.

The IRONFIST oscillating multi-tool is best suited for existing Milwaukee M18 battery owners who need an affordable cordless oscillating tool for occasional DIY renovation tasks — trimming, sanding, and scraping a few times a year — and want to avoid the premium price of a branded Milwaukee equivalent.
