So, if you’re unsure which is the best sander for wood or which tool is the right fit for your project, fear not! Our comprehensive guide to this handy handheld tool will walk you through everything you need to know about sanding tools.

What is a Sander?

A sander is a handheld power tool that is used to smoothen rough or uneven surfaces. Sanders can be used on a variety of materials, but are most commonly used on wood, plastic and metal to prepare them for painting or finishing. However, sanders can also be used to remove layers of old paint and rust. There are a range of different types of sanders designed for specific tasks, and that’s what we’re going to explore in this guide.

How to Use a Sander

Using a sander to smooth out your surfaces couldn’t be simpler! It may vary slightly depending on the sander you choose, but ensure that you are always manoeuvring the sander in the direction of the grain. Going against the grain could result in splinters and damage to the surface your sanding.

Types of sanders

1. Belt sander 

If you want to remove a lot of material from a large area sharpish, an electric belt sander is probably the best tool for the job. With a sanding sheet made up of fine, abrasive grit, a belt sander is the perfect option for sanding tabletops, doors and edge sections of timber flooring. The best choice for heavy duty sanding tasks, belt sanders are highly effective at removing old paint, smoothing rough surfaces and shaping wood (sanding doors to fit, for example).

A belt sander works by using a belt of abrasive sandpaper stretched over rollers. Many of our models also feature a dust collection bag to reduce mess as you work – you can also secure some models to a workbench with clamps for stationary use. A sanding frame can be a helpful extra if using a belt sander – this useful accessory limits the depth of sanding for an even, level finish.

2. Sheet sander

A sheet sander is popular for woodwork as it has both shaping and smoothing properties. It consists of a rectangular base with an attached handle. They are not as abrasive as belt sanders, making them less effective at shaping large areas, but reducing the likelihood of leaving marks on the surface. If you’re wondering what the best sander for wood is, we recommend a sheet sander.

3. Random orbital sander 

An orbital sander (also called a finishing sander) is your best bet for getting a smooth finish on large flat areas. It can also be used for smoothing plaster, paint or varnish between coats. The base plate, available in different sizes, moves with a tight, rapid circular action that minimises scratching.

The random orbital sander combines the speed of a belt sander with the smoothness of an orbital sander. It features circular sanding discs that ‘orbit’ and rotate simultaneously. This leaves the surface virtually scratch-free and spreads wear on the sanding sheets more evenly, so they last longer. A flexible backing pad means the sander can cope with gently curved surfaces. This tool type is also known as an eccentric sander.

4. Detail sander

A detail sander is a hand-held tool, sometimes also referred to as a ‘corner’, ‘delta’ or ‘mouse’ sander. It uses a vibrating head with a sandpaper attachment that is usually triangular in shape. They’re great for sanding in tight spaces and into corners that can’t be reached by larger orbital or belt sanders.

5. Multi-sander 

Multi-sanders are fantastically versatile! Combining features from detail and orbital models, the multi-sander is good for treating both flat and contoured surfaces. You can also use special attachments for working on ‘profile’ sections such as skirting boards and architraves.
