Die Grinders
Die Grinders are some of those most useful tools in any collection. Even if you think you might not have a use for one, once you own one you suddenly can't live without it. When shopping for a die grinder, the tool's RPM rating should be the first thing to consider. Die grinders that spin at lower than 10000 RPM are best suited for finishing work and fine grinding. In contrast, grinders that rotate between 10000 and 20000 RPM are better for rougher grinding and minor buffing projects. If the unit is rated for over 20000 RPM then it is well-matched for removing burrs and cutting metal.
