10 Best Oscillating Spindle Sander For Sanding Curves in Wood

10 best oscillating spindle sanders

Last updated on March 10th, 2021 at 01:48 pm

There are different types of wood sanders out there. Some of them can be used interchangeably, but the oscillating spindle sander has its own peculiar function.

Its primary function is for sanding detailed or curved wood pieces. A typical oscillating spindle sander consists of a rotating circular drum covered with a sleeve of sandpaper which also oscillates or moves up and down simultaneously to prevent the rotating action of the drum from burning the wood up.

The oscillating action of the drum also ensures that the wear on the sandpaper is spread evenly, ensuring a longer lifespan for the sandpaper.

There are different models and sizes of oscillating spindle sanders. They include floor models which are used as a stand-alone unit, benchtop models which needs to be mounted on a workbench or table top, and handheld models which as the name implies can be handled with your hand, running it over a stationary work-piece, and not the other way round.

Floor models are larger and are more expensive. They’re ideal for the professional woodworker who wants to use it for handling large commercial projects. Benchtop and handheld models on the other hand are smaller and more budget friendly.

The following are out top picks from the 10 best oscillating spindle sanders we reviewed in this article.
