Side by Side: Angle grinders

Agriculture.com Staff 01/24/2006 @ 2:35pm

If you weld or fabricate metal, you know how important an angle grinder is from start to finish. Grinders are available in a variety of sizes. So it’s important to choose a size that is appropriate for the task at hand. Larger grinders can cover more area with their larger wheels but are heavier and can cause fatigue. A smaller size may be more appropriate and manageable for smaller jobs.

Each wheel has an rpm (revolutions per minute) rating. Be sure that the wheel has a rating equivalent or greater than the grinder’s maximum no-load rpm. This recommended level is usually on a tool’s nameplate.

The variety of wheels you can equip grinders with (wire, wire cup, stone, sanding, flapper, and diamond masonry joint blades) makes them highly versatile. Selecting the proper wheel is not only a safety measure but also lends to better control and efficiency. Some manufacturers, such as Bosch, label wheels with symbols to designate the right applications.

In addition, operators should wear the appropriate protection gear, such as wide-vision goggles, earplugs or earmuffs, and flame-resistant gloves that fit well for a firm, two-handed grip. Because a firm grip on the tool is imperative, consider whether the handles are adjustable for right- and left-hand use.

Grinder manufacturers are continually making modifications for improved safety, comfort, and better performance. For example, some new angle grinder models have cut vibration by 60%. The vibration-reduction handle system was first offered in small angle grinders and is now available in larger models.

Read about some of the angle grinders available and the features they offer on the following page.
