The Right Grinding Tools for Your DIY Tasks
Grinding tools are the star of the game when a surface needs to be smoothed or partially removed.
Grinding is indeed not the favorite occupation of most craftsmen. However, you will not be able to avoid the use of a grinding tool, especially when it comes to furniture construction or restoration.
After all, a good result not only takes time but also raises a lot of dust. It makes the selection of the right grinding tool all the more critical. Random orbital sanders, angle sanders and the like - we tell you which sanding tool you need to use and what you need to look out for when you buy it.
In principle, all grinding machines have the same task: smoothing or removing surfaces. But not every abrasive tool is suitable for every job. We'll tell you which tool will meet your requirements:
Random Orbit Sander
If you are thinking about buying a sander, an orbital sander is usually the best choice because of its versatility. Due to its regular, eccentric grinding movements, it ensures an even and fine grinding pattern while provides relatively rapid work progress. An eccentric sander is also suitable for all surfaces. You can use it to sand all types of wood, metal or plastic.
The angle grinder is the grinding tool for coarse sanding. It allows thick layers of paint to be sanded effectively and quickly with the angle grinder. However, the high rotation speed also means that the sanding result is usually not even. For example, after working with the angle grinder, fine grinding is often carried out with another machine.
Due to their large sanding surface, these sanders are mainly used for sanding large surfaces. Tabletops, cabinet sides and the like are sanded with a belt grinder in the twinkling of an eye.
However, the sanding is also rather coarse here, so you must use a further sanding tool. Care must also be taken with all the round surfaces, as these can be ground through correspondingly and quickly.
Disc sanders are usually larger floor-standing machines. As such, it is limited to smaller workpieces. Often, the processing pieces of wood in model making use these sanders to execute the work.
Caution: Always place the workpiece on the side to which the plate turns. Otherwise, it may be torn from your hand.
The grinding tool is the selection of the right abrasive paper and the corresponding grit size.
The following applies: the larger the number, the finer the grit and the coarser the sand, the rougher the final result.
For a simple wood sanding you can remember: a grain size between 40 and 60 is used for coarse removal of paint and varnish; a grain size between 80 and 120 for coarse rough sanding and a grain size between 150 and 240 for fine sanding.
The choice of sanding paper is always dependent on the material and your sanding technique. So, do not hang yourself too much on the numbers, but choose the abrasive paper that works best for your specific situation.
