Safety Information

Oscillating multi tools are generally amongst the safest power tools to operate due to their controlled oscillating action rather than continuous rotation. However, appropriate safety precautions remain essential. Always wear suitable eye protection to guard against flying debris, particularly when cutting metal, masonry, or materials that may shatter. When sanding, scraping paint, or working with materials that generate fine dust, respiratory protection conforming to HSE guidelines is vital—particularly important when dealing with older paints that may contain hazardous substances.

Ensure materials are properly secured before cutting or sanding, and maintain a firm grip on the tool with both hands where possible. The oscillating action generates relatively modest kickback compared to rotary tools, but maintaining control remains important. When performing plunge cuts, ensure you know what lies beneath the surface—pipes, cables, and structural elements can be hidden within walls and floors. Always disconnect corded tools from the mains supply (or remove batteries from cordless models) before changing accessories, even those with tool-free systems.

Hearing protection should be considered during extended use, and appropriate work gloves can protect against sharp edges on materials being cut. Never bypass or remove any safety guards, and ensure adequate ventilation when working indoors, particularly when cutting or sanding materials that produce dust or fumes.

Frequently Asked Questions

What's the difference between OIS and Starlock blade systems?
OIS (One-Fit System) is a universal mounting standard using a simple clamping mechanism, found on many mid-range tools and offering wide accessory compatibility. Starlock is a more advanced system featuring a 12-point star interface that provides superior blade retention and power transfer, particularly beneficial for demanding professional applications. Starlock Plus and Starlock Max variants offer increased torque capacity for industrial use. Blades are not interchangeable between systems without adapters.

Can oscillating multi tools cut through nails and screws?
Yes, when fitted with appropriate bi-metal or carbide-grit blades designed for metal cutting. This makes them invaluable for flush-cutting nails and screws during renovation work, such as when removing old skirting boards or architrave. However, cutting through ferrous metals generates significant heat and dulls blades relatively quickly, so having spare blades available is advisable for projects involving substantial metal cutting.

Are cordless oscillating multi tools powerful enough for professional use?
Modern 18v cordless oscillating multi tools from professional ranges—such as DeWalt XR, Milwaukee M18, Makita LXT, and Bosch Professional—deliver performance comparable to corded models for most applications. Brushless motor technology and high-capacity lithium-ion batteries provide extended runtime and consistent power delivery. For site work and situations requiring portability, 18v cordless models are the preferred choice amongst professional tradespeople.

How long do oscillating multi tool blades last?
Blade longevity depends heavily on the materials being cut and the quality of the blade itself. Wood-cutting blades may last through several projects when used on softwoods but wear more quickly on hardwoods or abrasive materials like MDF. Bi-metal blades cutting ferrous metals or nails may only last for a limited number of cuts. Premium blades from manufacturers like Bosch, Fein, and Festool generally outlast budget alternatives, making them more economical for professional users despite higher initial cost.

What's the advantage of variable speed control?
Variable speed allows users to optimise the oscillation rate for different materials and applications. Slower speeds provide greater control for delicate work, reduce heat generation when cutting plastics (preventing melting), and minimise material damage on visible surfaces. Higher speeds enable faster material removal when sanding, more aggressive cutting through dense hardwoods, and improved efficiency on robust materials. This versatility makes variable speed models significantly more capable across diverse applications.
