18V Cordless Angle Grinder is suitable for workshop, construction & home DIY use.
Before you use an angle grinder, you’ll want to grab some personal protection gear. The reality of the angle grinder is that it’s a loud tool that kicks a whole lot of debris around. Plus, you’re not always grinding or polishing. Oftentimes, the job entails cutting. If you get sloppy with a cutting wheel or simply have bad luck, that wheel could turn into high-speed shrapnel.
For these reasons, grab some hearing protection, long sleeves, gloves, and something to shield your entire face.
Before applying the grinder to the work surface, allow the tool to reach full speed. You’ll do a better job of keeping your cuts and grinds consistent.
For grinding and sanding applications, keep the tool moving so as to avoid gouges just like you do with a sander. You’ll end up with much smoother and more professional results.
Some grinders have lock-on switches. These have the potential to come on whenever they receive power. That means that if you swap out a battery, attach an extension cord, or reset a breaker, you want to make a habit of turning the grinder off first. Some grinders have a built-in “zero voltage” safety to avoid kicking on automatically, but not all do. This is a great safety feature.
Make sure everything stops spinning before setting the angle grinder down. Even a lightly spinning blade can damage work surfaces and grab loose clothing. A braking grinder (grinder with an electric or mechanical braking system) really helps avoid these problems.
Occasionally, you’ll want to remove the guard when it gets in the way. Many Professionals have at least one story about a cutting wheel shattering. Most shrouds rotate to make life a little easier. Most of these tools spin at over 10,000 RPM. In general, you want to keep that guard on no matter what!
