We owe the ancient Egyptians a truckload of gratitude for creating the ‘lathe’ – the first recognized power tool. Because of them, we now have more than 100 power tools that are used in the industries, construction sites and even in homes and gardens. From power sanders and fast cutting chainsaws to washing machines and powerful leaf blowers, the importance of power tools to this generation cannot be overemphasized. Now we've covered the gratitude, let’s focus on one of the most important power tools ever invented – the angle grinder.
An angle grinder is a power tool that can be used for grinding, polishing and cutting. It’s found applications on construction sites, and in service garages, workshops and even shops where auto body repairs are carried out. In the home, it can be used to remove unwanted material from something, sanding and even blade sharpening. Unlike a hand plane that can be described as a hand tool, the angle grinder can be powered by either electricity, gas or compressed air. This is a huge advantage over hand knives, pliers and cutters.
There are numerous brands and models of angle grinders and to avoid complicating issues for yourself, you should know the project the unit would be used on before purchasing one. DIY and home projects require small and portable angle grinders while professional projects require larger angle grinders capable of executing the job at hand. There are several factors that may affect the power generated by the grinder and they include the disc size, amp and speed rating. These factors must be carefully considered before making a purchase to avoid buying the wrong angle grinder.
Now you know a bit about angle grinders, you can also visit our review of the best power grinders available. There's not much difference – only that a power grinder encompasses more tasks. No matter the choice you make, you can rest assured that all your grinding, cutting and polishing needs will be taken care of.
As with most power tools, the higher the power, the higher the cost. That’s not to say an angle is expensive, but there are different factors that may affect the cost. The type of angle grinder being considered plays a huge role in how much it will cost. A gas powered or compressed air-powered angle grinder costs more than the angle grinder that can be powered by battery or AC wall outlets. Also, depending on the brand and model, an angle grinder with a larger disc size and motor power will cost more than one with a smaller size and power.
With considerations to the above factors and their effect on the cost of an angle grinder, the temptation to settle for a cheap angle grinder is increased. That would be a dangerous risk not worth undertaking because such angle grinders are not powerful and durable enough.
There are efficient, powerful and low profile designed angle grinders that cost between $50 and $300.
One huge mistake people tend to make while purchasing an angle grinder is thinking that all angle grinders are the same. It is a very wrong notion and if care is not taken, the tendency to buy the wrong angle grinder is increased. To avoid such mistakes, it’s important to determine your needs before making a purchase. These needs will in turn determine what features the angle grinder should have. However, here are the most important features to consider before purchasing an angle grinder:
Usually, angle grinders are classified according to their power source. Based on this classification, angle grinders can be described as either electric (AC or DC), gas or compressed air-powered (pneumatic). Amongst these 3 types, the electric powered angle grinders are the most common. The power in this case can either be derived from a battery or wall outlet. It’s not suitable for heavy duty application and has been mostly used by do-it-yourselfers for basic applications. Angle grinders that are gas powered are more powerful than electric ones and have found great use on construction sites. It is, however, more expensive and difficult to use. Lastly, the pneumatic angle grinder, which is also as expensive as those powered by gas, can be found in auto and metal fabrication shops. It is powered by compressed air and cannot be used for DIY use.
As a rule, an increase in the size of an angle grinder’s disc automatically leads to an increase in power. A DIY angle grinder user may not require as much power as a pro on a construction site. The sizes of the disc vary greatly, with the most common being 230mm (9 inches) and 115mm (4.5 inches). However, it’s important to note that pneumatic grinders usually have smaller discs but they are more powerful and precise than other conventional angle grinders. Since the disc size affects the power generated, you should also know that the speed at which it rotates is important. This refers to the speed rating. When powered, an angle grinder’s disc can create from 5000-10000 rpm (revolutions per minute). While this speed is sufficient for any cutting, polishing and grinding task, it can also pose an injury threat if not handled carefully.
When it comes to the power generated by angle grinders, we are referring to the amp, wattage and voltage ratings. For the power rating, there are grinders with ranges from 500 to 2500 watts. As for voltage rating, you can choose between 110V and 230V AC, while for current rating, you could for a unit with amp rating from 4-15 amps. When considering the amp ratings, please note that they are directly proportionate to the power yield. What this means is that an angle grinder with a 4-amp rating will yield less power than one with a 15-amp rating. However, grinders for household use don’t require as much amp rating as an angle grinder for construction sites or professional projects.
The size and weight of an angle grinder impacts the level of operational comfort. Because of the many brands and models of angle grinders, it would take more than a day to list all the dimensions and weights! However, if your intention is DIY use, a smaller unit weighing less than 10 pounds will be sufficient. To increase the level of comfort, it’s also advisable to get an angle grinder with an anti-vibration handle. This allows the user to hold it for a longer time, without feeling the kickbacks as much. For industrial and commercial purposes, however, a larger unit will work better. Also, an angle grinder with a dust management feature in place is helpful. Such a feature increases the ease of working and prevents you from having a dust problem.
An angle grinder, like all power tools, can pose a serious injury threat if handled carelessly. Hence, it’s imperative for users to be fully acquainted with the safety precautions and capabilities of the angle grinder before using it. When not in use, unplugging the angle grinder is the ideal thing to do, to avoid any mishap. When in use, ensure the safety guard is always used. Lastly, a face mask, eye shield, sleeves that are long enough and thick work gloves should be worn before performing any operation involving the angle grinder. After successful completion of the task at hand, unplug the power tool, and store in a safe place.
