How Can Angle Grinder Be Helpful to You? – Angle Grinder Benefits

Cleaning the Weld

Cleaning the weld is where you’ll find this angle grinder most useful. Spinning at speed on steel helps remove any impurities in the weld like excess metal, loose flakes of burnt material, or simply the blueing that happens when steel turns white-hot in welding.

You’ll find the grinder also does a better job than sandpaper as it gets into those hard-to-reach areas and straightens out the weld, so it’s smooth and even with the surrounding steel.

Removing Paint From Metal

The same goes for removing paint from metal; now that it’s okay and without a wire cup brush, you may find you have to scrape at the surface with a blade until your arm drops off before all the paint is gone.

Not with an angle grinder, a quick spin over the surface of the paint, and it’s gone before you know it, so your blade can have a go at simply grinding down to the surface of the metal.

Cleaning the Metal before Welding

What about when you’re starting to weld, and there’s grease, oil, or dirt on the surface; don’t let it get in the way of a good welding job. A quick spin with the angle grinder and any dirt or grease is gone, leaving a clean surface for your machine to work on.

Removing Rust

No matter whether it’s in a hurry to clean rust from something before welding or have your angle grinder in hand for when you need to remove rust, simply speed up the grinder and grind all over it with ease.

Cutting Metal

If you’re cutting through steel or some other metal, the angle grinder is pretty much the only way to go. It’s not like a wire brush that just chops it away in large chunks, and the fine wire removes metal slowly and smoothly without sticking to the blade or stopping you from cutting through it.

Restore Cutting Edges

Restoring a cutting edge is another thing you’ll find the angle grinder helpful with. This is because, unlike blades for sanders, the grinding disc isn’t made of any delicate material.

It’s designed to simply grind down metal through friction and heat rather than shaving it off at the microscopic level like a sander’s blade.

Precaution

You’ll need to wear goggles when using an angle grinder for safety and to avoid getting dust or other material in your eyes.

How Do I Choose an Angle Grinder? – Buying Guide

Angle Grinder Disc Sizes

The first consideration is the size of the disc you need. The most common are 4-inch, 5’s, and 6-inch grinders, though the larger the disc, the more it weighs, so you may need to settle for a compromise between weight and size.

A common mistake is to assume bigger is better and buy a grinder with the largest disc you can find and struggle under its weight.

Choose between

  • 4-inch angle grinders have the best all-purpose applications, being light enough to carry around and powerful enough for most jobs.
  • 5-inch angle grinders are the most popular because of their good power-to-weight ratio, being powerful enough for most jobs without being too heavy.
  • 6-inch angle grinders are the best for large grinding jobs, as smaller angle grinder can’t match their power-to-weight ratio. However, they will weigh considerably more.

Ergonomics

Choosing an angle grinder is mainly about finding the right balance between weight and power. Get one that’s too weak or heavy, and you’ll have to put up with uncomfortable or clumsy handling.

Not all brands produce angle grinders of the same weight, so it’s a matter of finding which ones you’re most comfortable with.

Safety

Grinders have a rotating disc, so be sure to wear goggles and gloves to avoid injury.

Also, look for a tool with a lock-off switch to prevent accidental starting.

Speed

The speed of the rotating disc is measured in revolutions per minute (RPM). The higher the RPM, the faster it spins.

For most jobs, a speed of between 5,000 to 10,000 RPM should be plenty.

For cutting and rust removal, a grinder with 12,000 RPM or more will be better.

Corded Angle Grinder or Cordless

Angle grinders are available in both corded and cordless versions.

Corded angle grinders have the power to get any job done but will be heavier. Cordless grinders are lighter and have good freedom of motion, but the battery only lasts around 10-15 minutes before it needs recharging.

Tool Warranty

Make sure you check the warranty of any tool before buying it to make sure you’re covered in case there are any problems.

Some come with a one-year warranty, while others offer two years.

Slow Start

Some grinders allow the speed to ramp slowly when you first turn them on, which reduces the stress on their internal components. Look for this feature if you can.

Variable-Speed or Fixed Speed

Some models allow you to adjust the speed of the spinning disc, which is suitable for fine-tuning.

Also, it’s easier to control a grinder with a variable-speed control.

Dust Sealed

A grinder that’s sealed against dust will stand up better to prolonged use. Hence, you can use it for longer before it needs servicing or replacing.

Hand Guard

To avoid injury, look for a grinder with a hand shield. Some also come with guards on the front and side of the disc to protect you even more.

Side Handle

A side handle is suitable for jobs like removing rust and paint as it lets you move your arm freely.

A trigger grip is good for small jobs as it lets you control the speed with your thumb and fingers, though they can’t be as precise as side-handled or 3-finger disc grinders.

Angle Grinder Motor

It’s also important to consider the motor power. The more powerful it is, the faster you can do your job.

High-power angle grinders are for heavy-duty jobs, while low-power models are less powerful but lighter and easier to control.

Disc Guard

Some tools come with a metal disc guard that goes around the outside of the wheels to shield you from sparks and flying debris. If not, it is a good idea to buy a separate one as a safety measure.

Some more advanced models have dust extraction facilities, allowing you to hook a vacuum cleaner up to them and suck away all the dust as you grind.

The standard disk guard provides enough protection if you wear gloves, a full-face shield, earplugs, and a dust mask.

Loud Noise

Loud noise may damage your hearing. You’ll need to wear earplugs or other protection while using the angle grinder.

Durability

High-end low-speed electric angle grinders are long-lasting thanks to their high-quality craftsmanship.

Price

Upper mid-range angle grinders are the most expensive, with high-end models being cheaper.

You should pay more for higher-power angle grinders, as they are more robust and faster.
