To understand how to use an oscillating multi tool or multi-cutter we need to look at how it works. So how does a multi tool work?
The larger, more powerful multi-tools use a vibrating, oscillating plate, or mounting platform where the various blades and attachments are attached. These plates vary in oscillating speed and can easily reach speeds of 20,000 times per minute. Some tools will have a fixed speed platform whilst others will be variable speed.
When using a multi tool make sure that you wear the correct protective gear such as ear defenders, goggles, and gloves. The tools can emit noise levels greater than 90 dB.
Because of the ergonomically sophisticated designs of the grips and the small displacement but fast blade movements, you can use them in tight, difficult-to-reach places and for cutting unusual items such as sawing plunge cuts in plasterboard or sawing openings for locks and fittings. Once the chosen blade or tool is attached it can be offered up to the item that you want to work on. Applying gentle pressure to the workpiece will cause the fast, efficient oscillating tool to do all the hard work for you.
