Tips for using an angle grinder
Here’s what you should keep in mind when it comes to buying/using a angle grinder:
- Angle grinders are popular for DIY projects, so using 4 ½ or 5” grinders for those jobs are common.
- If plugged in, you should turn off the grinder while changing wheels, so that your hands don’t get cut off.
- Run the wheels for a minute, to make sure it’s not defective. The worst thing is having defective wheels and that could affect performance/safety.
- Because grinders have higher RPM’s, you’ll want to make sure you’re not near any flammable materials. You will definitely have sparks when you’re grinding so this is something to remember.
- For safety reasons, make sure you use both hands on the grip. It can be a bit dangerous if trying to do it one handed.
- You would have to watch out for HAV (Hands, Arms, Vibration Syndrome) which is a condition that’s caused by constant vibration and can cause symptoms such as pain, numbness and loss of grip. You should always make sure that’s you can hold on to the grip comfortably, so you don’t develop HAV.
- This is a no brainer, but you should always wear some PPE. Safety glasses, hearing protection and a mask. You’ll prevent unnecessary health issues and it’s for your safety.
- To ensure the disc and guard are correctly attached and tightened, check the grinder before use. Disks and guards may get loose among uses. Tighten them until the power is added to the grinder angle. The last thing you want is an accident because no safety precautions were taken.
- You’ll want to make sure that the angle grinder is always in a clamped/secure place, preferably in your workshop, away from children and pets, so they can’t reach it.
- Buy angle grinders from well-known brands. Why? Because they have a warranty that they usually honor in case the grinder is faulty or doesn’t work anymore. Buying from a brand that has no warranty just leaves you with a tool that’s on it’s way to the trash can.

What is an angle grinder?
Angle grinders are usually battery-powered or have an electrical cable, although pneumatic (air-powered) models are also available. There exists a threaded spindle which is placed at the 90° angle of the body of the instrument with a single nozzle that locks the spindle with different attachments.
The fastener locked to the spinning spindle would spin to 12,000 rpm with a decent amount of torque when the angle grinder is triggered. This makes them very impressive in cutting, grinding and polishing. The measurements vary from 4 to 9 inches with mostly inch intervals in between, which are determined by the largest disc that can match the grinder.
