Angle Grinder Reviews
Our Top Pick is the Dewalt DWE4012
Angle grinders are very versatile power tools that are used to grind, sand, and cut a wide range of materials. This is done by adding different attachments or wheels for the jobs that need to be done. Want to clean dirt and clay off shovels and hoes use a wire wheel. A cutoff wheel is used to cut hard metals like rebar, rods or bolts. Diamond head wheels allow you to cut tile and the grinding wheel will take care of all your sharpening needs from lawnmower blades to axes and shovels. An angle grinder has the ability to clean off rust or other tough dirt or debris that have become embedded in different tools. This includes removing mortar from brick without damaging the brick or the area around. An angle grinder would also be an excellent tool for cutting angled tile pieces or sanding down woodworking projects. They can be used on a variety of materials such as brick, wood, steel, stucco, and many others, along with being able to cut and trim down materials.
What makes an angle grinder so versatile are the attachments you can use. These each perform a different job and come in a wide range of sizes, and textures each designed for a specific task. Some of the most common attachments include a sanding disc, grinding stone disc, cutting disc, stainless steel wire wheel, carbon steel wire wheel, and a sanding flap disc. The attachments are each designed for a different job and are built from various materials to tackle all different forms and thickness of metal, brick, wood, and stone. The most common of these attachments is the grinding stone disc which is specially designed for grinding metal.

What Makes a Good Angle Grinder?
Most homeowners and small shop owners do not need to invest in a high end model to get the performance you need for everyday projects. Less expensive grinders generally do not have the power needed to perform more than basic work and have weaker motors that will burn out faster. Higher end models have more power than most homeowners will ever use.
Angle grinders come in electric (both corded and battery powered), gas, or pneumatic. For most users an electric grinder will offer the power and convenience needed to complete the job. Corded units are more cost effective and more powerful at the same price point. Battery operated units are higher priced but more portable and you don’t have to ensure the cord is away from the wheel during use adding to its convenience.
When considering angler grinders there are several features that you will want to consider that easily separate the good angle grinders from the best angle grinders the first quality being the motor. The best angle grinders are going to have higher no load RPMs such as 10,000 rpms or higher, to provide a faster and more effective sanding and material removal abilities, and will also provide higher overload protection. Another factor to look for is filters or technology that protects the motor from intake debris that can wear a motor out prematurely.
Next you will want to look for an adjustable guard. These guards are placed partially around your attachment in a “C” shape to protect you from debris and loose materials being thrown back at you while working. On the best angle grinders these guards will be adjustable so you can maneuver them into the position that best protects you, as well as allowing you to reach your material comfortably and safely.
Another quality found on many grinders is a side handle. These side handles can be attached on either the right or left side of your toll to accommodate both left and right handed users. A handle will provide control and comfortwhile using the grinder. The handle can be compared to bike handles and are equipped with grips and a comfortable padding to ensure a no-slip grip and easy glide.
Up next is the weight. Angle grinders are tools that are going to be constantly up and in motion so finding a lightweight angle grinder will reduce user fatigue and aiding in control. The best angle grinders, and even the most expensive, high quality angle grinders should be under ten pounds and fairly compact for maximum efficiency. Tool Vibration will also play a factor in your comfort.
