A bench grinder is a tool which spins grindstones, and these grindstones gently shape metal.They can quickly sharpen blunt tools.Most bench grinders run at about 3,450 rpm, although there are more and more variable speed grinders on the market these days.
Air grinders are typically used in confined areas for high-speed polishing and grinding.They provide additional reach when trying to shape material or smooth metal joints, remove paint or primer, and debur materials.Air pencil grinders provide precision for detailed and intricate work in grinding, deburring, finishing, and cleaning.
Air-powered grinders come in several main designs, including straight, 90-degree, and 45-degree.This refers to the angle of the tool head versus the grip.Straight grinders typically offer more control for detail work using grinders and burr bits, while angle-head tools work really well for tight spaces and sanding/surface prep work.
Angle grinder discs have a maximum safe RPM that they should be operated at, which prevents them from breaking apart while in use and potentially causing an injury.Make sure that your right angle grinder does not exceed the recommended RPM for the product you are using, bearing in mind that most right angle grinders run at a fixed speed of .
Angle grinder speed is defined in revolutions per minute (RPM).Speeds typically range between 5,000 and 10,000 RPM, though some very robust grinders reach up to 12,000 RPM.
