Angle Grinder Buying Guide
What is an Angle Grinder?
As you well know, every metal worker eventually needs to do some cutting, grinding, or polishing, and that’s where an angle grinder comes in handy. An Angle Grinder or disk grinder is a handheld tool and is either powered by an electrical motor (battery or AC), or compressed air.
With an angle grinder, you’ll usually find a geared head, an abrasive disc, an adjustable guard, and a side handle. The geared head is usually mounted at a right angle and holds the disc or wheel that will cut, sand, polish, or grind a wide range of materials.
You’ll often find angle grinders in auto shops, metal shops or construction sites. Most of the time, they’re used to smooth or remove excess material, and to make cuts or notches. You will find multiple different angle grinder discs such as: abrasive grinding discs, grinding stones, cut-off discs, sanding discs, polishing pads, and wire brush wheels.
If this is a lot of information for you, and you simply don’t know where to begin, this buyer’s guide will help you to pinpoint what kind of angle grinder you need to get the job done.
What are the Common Uses for an Angle Grinder?
When you hear the name, you might think that an angle grinder only serves one purpose, but in fact it can serve a number of tasks.
Grinding: The most common use is grinding or sanding away any protruding or unwanted stone, mortar, or metal. You’ll often find metal workers use these tools when they need to remove dross (slag), or when they’re working with metal and shaping stone.
Blade Sharpening: Aside from polishing and cutting, angle grinders can sharpen tools and blades with ease. That means that you’ll be able to sharpen common tools such as axes, mower blades, and even shovels. Just make sure that the item you are grinding is securely attached to your work table before attempting to sharpen.
Mortar Removal: An angle grinder is useful for tuck-pointing. You can remove old, loose mortar without damaging the brick. This avoids any strenuous labor and is way faster than using a chisel and hammer.
How Do I Operate an Angle Grinder?
An angle grinder is a handheld power tool that works via a power source to rapidly spin a disc. To operate the tool, you must press a switch (trigger). I have even seen a few where you flip a safety shield and then you can pull the trigger. Now, when you let go of the switch, the grinder turns itself off. This is what’s known as the “dead man switch” and is there to protect you from injury.
Some grinders have a side handle grip. This stabilizes the grinder so that you can perform the task at hand. Most angle grinders can adjust for left handed use.
Always make sure to wear the proper safety glasses/shield, gloves, steel toe boots and depending on what types of material you are grinding, proper respirators/face masks.
What are the Wheel Types and Uses?
1. Aluminum Oxide: Used for woodworking, buffing/polishing, and cutting bolts, rods and bars.
2. Diamond: Ideal for cutting concrete, stone, and tile and other hard materials.
3. Fiber: Appropriate for rust and burrs.
4. Flapper: Suited for sharpening tools, grinding, restoring edges, sanding, and surface prepping.
5. Silicon Carbide: Meant for sharpening, and cleaning metal, as well as tuck pointing and removing mortar.
6. Wire or Brush: Suitable for cleaning metal by removing paint and rust.
What are the Considerations When Buying an Angle Grinder?
There are a few things you should take into account when trying to find the best angle grinder for your situation. There is a wide selection available and a number of sturdy makes and models to choose.
Many may want to buy an inexpensive model, but you should only do this if you plan to use the tool infrequently or for smaller projects. If you are going to use your angle grinder more frequently then, you want performance, power and safety. To get such, you should be willing to spend a bit more.
Keep in mind that the greater the size of the angle grinder’s disc, the more powerful its motor. There is a variety of disc sizes to choose. The most popular are 4.5 inches (115 mm) and 9 inches (230 mm). In some cases, a pneumatic grinder might be ideal with its smaller disc sizes. These tools allow for more precision on small jobs.
You’ll find different voltage, wattage, and amp ratings for each angle grinder. Generally, your choice will be between 500 and 2500 watts, and amp ratings that range from 4 to 15amps. Obviously, these numbers will correlate with the power of the motor. A lower rating should be adequate for most household tasks.
These are powerful tools, and the unit’s disc can make anywhere from 4,000 to 15,000 revolutions per minute (rpm). Know that the higher the speed rating, the higher risk of injury if the angle grinder is not handled correctly.
There are two components that relate to comfort of use, and these are size and weight. Unless you intend to use the tool for large industrial jobs, you may want a smaller unit that is more comfortable to hold. Compact units are easier to use for long periods. Be sure to look for a model that features anti-vibration handles—trust me on this.
Wheels and Accessories
These are incredibly versatile tools, and the discs can be interchanged. You can also install different wheels and accessories for the ultimate in versatility. Make sure to read the instructions to make sure that you are buying the right tool for your job.
NOTE: Make sure you select the proper disk size or attachment for the motor and speed rating. An incorrect match will result in damage to the grinder and can cause injury when the wheel breaks.
An angle grinder is a versatile and while we may make fun of it from time to time, they do serve a purpose. Any of the units above can serve multiple needs and provide a long lasting powerful tool in your arsenal.
