Buying Guide – What To Look In The Best Angle Grinder:

Here is a detailed buying guide that you should go through before deciding an angle grinder for yourself.

Power Source:

Angle grinders, like many other power tools, are divided into two types: corded and cordless. Although pneumatic angle grinders are available, most people who do their own home improvement use them at professional auto shops.

Corded angle grinders require you to keep close to an electrical outlet in exchange for increased power and the assurance that your battery will not run out before you finish your operation. Cordless angle grinders are quite adaptable, especially when working in small spaces, but the power may run out before you are through. But, having two batteries allows you to use one while charging the other, which solves the problem.

Size of Disc:

Angle grinders that accommodate 4 1/2-inch or, on rare occasions, 5-inch discs are the most popular among DIY enthusiasts. These angle grinders are lightweight, small enough to fit in tight spaces (most are only around 12 inches long), yet strong enough to do the majority of routine grinding, sanding, or sharpening activities around the house, yard, or garage. Angle grinders in this size range come in both corded and cordless models.

Angle grinders with 7-inch or 9-inch discs produce greater power, but they are also heavier and more difficult to use in tight quarters. Almost all of these tools have power cords. While some DIYers may require these large angle grinders, particularly if they frequently perform auto repairs or undertake major remodeling projects, these tools are more commonly used by professionals who require the maximum in size and power to cut through concrete, steel, or other similarly difficult materials.

Speed of Angle Grinder:

The spinning disc of an angle grinder is measured in rotations per minute (rpm). Take in mind that the speeds given by manufacturers are frequently the maximum speeds the tool can attain when not “loaded,” that is, while not being used for sanding or grinding. Also, keep in mind that as the speed increases, the disc heats up. Never run a disc faster than its maximum speed because the disc may shatter and cause catastrophic injury.

Most smaller angle grinders offer variable speed settings, allowing you to tailor the speed to your specific needs. Its maximum rotating speed normally ranges between 5,000 and 11,000 rpm. The maximum speeds of bigger angle grinders are generally lower, ranging from 5,000 to 8,000 rpm.

Voltage or Amperage:

Angle grinders measure potential power output in volts (V) and amperes (A) (amps). Cordless angle grinders use volts to gauge the amount of power in their batteries. The bulk of cordless models run on 18- or 20-volt batteries, with outliers ranging from 7.5 to 24 volts. The “magic number” for the majority of cordless power tools is 18 to 20 volts because it delivers the best blend of price and functionality.

The voltage readings on corded angle grinders only show compatibility with 120-volt or 220-volt power outlets. Buyers can evaluate the potential power output of corded devices by checking at the amperage, which ranges from 5 amps to 15 amps. The theoretical power output of a 7- or 9-inch grinder should be higher because larger discs demand more power.

Hand Guard:

The guard of an angle grinder, which covers half of the disc, is a critical safety element. When using the grinder in limited locations, it protects the surfaces and protects the user’s hands from sparks and flying debris.

Angle grinders come with both moveable and fixed guards. The mobile model is more prevalent because it may be used by either left- or right-handed people and can be modified to provide better protection from flying items. A movable guard, on the other hand, runs the risk of falling off the gadget if the bolts are not tightened. Fixed guards are more durable and are less likely to dislodge from a grinder.

Soft Start: 

Angle grinders, being fast and powerful tools, may recoil slightly after being turned on. This is especially true when using a large and heavy grinding wheel. The angle grinder may leap into the user’s hands as a result of the motor’s rebound, seriously harming them.

Soft-start technology decreases the power output to the motor at first before gradually boosting it until the angle grinder is fully operational, reducing recoil. An angle grinder will not bounce during startup because of the throttled power output regulation, improving safety and decreasing stress on the user’s arms and wrists.

Types of Angle Grinders:

Angle grinders are classified into four types, each with its own set of benefits, limitations, and power sources. Angle grinders are frequently available with corded, cordless, pneumatic or gas power.

Corded or Powered Angle Grinders:

Corded angle grinders are among the most popular kinds because of their strength and endless power endurance. A corded angle grinder is limited by its cord, but it can be used for larger work without batteries or the expensive maintenance required by an angle grinder driven by a pneumatic or gas source.

Cordless Angle Grinder

Cordless power tools, which do not have the length limits of a power cable, allow users to use them wherever they choose, including outside. Because of developments in battery technology, certain cordless gadgets can equal the power of electric models. The only disadvantage of battery-powered grinders is that they typically have a runtime of just over 45 minutes if consumers do not have a backup battery.

Pneumatic Angle Grinders:

Pneumatic grinders use the air pressure from an air compressor to work. These would be only slightly less powerful than gas-powered angle grinders, and they may be highly expensive to purchase and operate, considering that air compressors need to be changed regularly because the refills are very little and don’t transport as much air. The pneumatic versions are more powerful and last longer than the corded versions.

Gas Angle Grinders

Gas angle grinders, like other gas-powered tools, are the most powerful types on the market. They are more expensive and heavy than other types of grinders. Also, gas-powered versions require a lot of maintenance and are not the greatest choice for modest jobs.

Tips of Using an Angle Grinder:

Keep the following points in mind when you are using an angle grinder. 

  • The most frequent angle grinder DIY activities, such as cutting tile or pipe, metalworking, or removing cement and mortar, rarely require more than a 4.5-inch angle grinder.
  • Hand-Arm Vibration Syndrome (HAVS) can be caused by the continuous vibration of an angle grinder, and symptoms include pain and a chilly sensation in the user’s fingers, loss of grip strength, and loss of sensation in the fingers and hands. The use of an angle grinder with a cushioned or vibration-absorbing grip protects your hands from constant vibration.
  • Personal protective equipment (PPE) such as safety glasses or goggles, hearing protection, and breathing protection should always be worn when grinding.
  • Before operating the grinder, ensure that the disc and guard are securely fastened. Discs and guards may become loose between usage. Tighten them before turning on the angle grinder’s power.

Frequently Asked Questions:

What exactly is the function of an angle grinder?

Angle grinders are versatile instruments that can be used for both amateur and professional tasks. They are especially useful if you routinely work with metal or masonry, such as concrete, brick, or stone. You only need the right blade or accessories.

As the name says, this is an excellent tool for removing burrs, defects, and rough edges from metal. You can also use your angle grinder to cut straight or curved lines, remove paint and rust, and buff or polish metal.

How do you cut pavers using an angle grinder?

With the right blade for the job—in this case, a diamond blade—your angle grinder can easily cut brick, stone, or concrete pavers. Almost any diamond blade for an angle grinder can be used to cut brick, concrete, and tile. If you intend to work with marble or granite, make sure the blade is properly designated for cutting stone.

How do you cut metal with an angle grinder?

Whether it’s rebar, a frozen bolt, sheet metal, or even steel, your angle grinder can simply cut through it. Never cut metal using a grinding wheel; instead, use the appropriate metal-cutting blade.

What is the most popular angle grinder size?

The most popular sizes are 4″ and 4 1/2″. These grinders typically accommodate wheels up to 7″ in diameter, with very compact ones accommodating discs as small as 3″.

How should an old angle grinder be properly recycled?

Rather than throwing away your old angle grinder, take it to a nearby electronics recycling site. While some home improvement businesses provide tool recycling programs, most municipalities and towns have programs for recycling computer equipment and other gadgets.

Final Words:

Finally, we hope you found our guide to the best angle grinders useful. Just remember to carefully examine the ratings of the grinders and, if you’re just starting out, then make sure to do your proper research before spending money.
