Buying Guide: Things To Consider When Select Angle Grinder

Angle Grinder

a) Size of the Disc

Angle grinders with a 4 12 inch diameter disc are the most common. For their portability, light weight and ability to fit into tight locations, these machines are a popular choice for welders. If you’re working on a large-scale industrial project, you won’t require a grinder with discs up to 7-9 inches in diameter.

b) Disc Swapping

Replace your angle grinder disc in a matter of minutes. If it’s a corded grinder, check sure the power is unplugged and the battery is disconnected. With a spanner given with the grinder, you should be able to remove the bolt that secures your disc in position.

The process of changing the dics on different grinders will be different, but it will be easy and there will be instructions included with the grinder. With the push of a button, some of our most popular models allow you to swap out discs. Maybe it’s just me being lazy, but I genuinely enjoy having a variety of grinding discs and settings available.

c) Type of Switch

One of the most common features on grinders is an on/off switch. You may turn it on with your finger by using paddle switches or flaps beneath. Some versions require you to start it with your thumb, which I don’t like, and an on/off switch can be more hazardous.

There is nothing more frustrating than trying to switch off an angle grinder only to have it fly out of your hands and start spinning around. When using gloves, slide-up switches might be a little uncomfortable.

d) Size

It is simpler to wield a small diameter grinder in one hand, which might be advantageous. Smaller size may also allow you to weld in more compact areas.

e) Safety

If you’re using an angle grinder, make sure you use goggles or other eye or facial protection, as well as gloves to protect your hands. Keep your eyes open and don’t take the danger of being blinded by a flying object, even if the disc’s guard will provide some protection.

Wear a leather apron and keep flammables away from your work area in order to prevent sparks from igniting them. In order to avoid injury, it is best to avoid purchasing low-quality discs. Once the angle grinder has been set up, be sure to follow all of the safety recommendations included in the user handbook before using it.

f) Price

Consider the cost of your angle grinder when making a purchase. With regular usage, cheap grinders won’t last long or be able to stand up to heavy use. Make sure you don’t treat it like a disposable item if you acquire a low-cost model.

It is possible to obtain a high-quality angle grinder if your budget is over $100, and there are many of mid-range options for under $75. Another factor to consider is the guarantee duration, which is often offered by the best-known manufacturers.

Frequently Asked Questions

Even if you have a thorough understanding of the finest angle grinders, you may still have questions. We’ve compiled a list of frequently asked questions regarding angle grinders so you can get the answers you want.

i. What kind of tasks can I use an angle grinder for?

Steel for welding and metal pipes are two of the most prevalent uses of angle grinders. In addition, these tools may be used for wood carving, refinishing, and other crafts. They’re even used by certain farriers to trim horses’ hooves.

ii. How are the discs on an angle grinder changed?

The first step is to unplug or remove the battery from the grinder. Remove the nut that secures the disc to the angle grinder using the factory spanner that came with the machine. Using the factory spanner, tighten the nut bolt on the new disc.

iii. How does an angle grinder operate?

For safety and security, hold the angle grinder with two hands after connecting the appropriate disc for the work. The disc will begin spinning as soon as you press the trigger or press the power button. The grinding disc should come into touch with the material you are cutting or grinding.

You should wait for it to stop spinning entirely, and then place it in a safe area, taking into consideration that the disc is still hot owing to friction created during operation before doing so. Allow the tool to cool down by unplugging the cable or removing the battery.
