Cutting floorboards prior to lifting - precise neat cuts can be plunged into a board directly above a joist with no risk to pipes or cables under the floor.This makes it ideal for a number of jobs: Unlike for example plunge cutting with a chisel, the cut has a very fine kerf. Equipped with the appropriate blade it can simply plunge into the surface of the material that is being cut, without touching or damaging anything adjacent to the thing being cut. One of the unique abilities of this type of tool is the way in which it can cut. An abrasive will similarly work back and forth over a surface. With its fine teeth, this is enough to cut any rigidly held material it comes into contact with. The end of a saw blade for example will swing back and fourth by a couple of millimetres. Its this oscillation that does the actual work. When running, the tool post rotates a very small amount in alternate directions, at a very high frequency (typically 20,000 oscillations per minute). The various tools are then firmly bolted or clipped to the post. Rather than having a fixed sanding pad that orbits, they have a tool attachment post.
However that is where the similarity ends. Tools on the market are available in both mains-operated and cordless (Li-Ion powered) models, at a wide range of price points.Īn oscillating tool, looks a little reminiscent of a detail sander, and in fact they do make very good detail sanders. They make very effective tools for performing awkward cutting operations that are almost impossible with any other tool. They can be used for cutting, sanding, rasping, polishing, scraping and a number of other tasks. Its a small versatile tool designed to perform a wide range of tasks. This article serves not only as a FAQ for this particular class of tool, it also documents the level of interoperability between the blades and accessories for the various makes. In recent years, a number of similar tools based on the multimaster concept have become available. The oscillating tool or "multitool", is a concept that was originally made popular by the German manufacturer Fein with their Multimaster range of tools.
