Things to Consider Before Buying an Angle Grinder

Whether you are buying an angle grinder for home jobs or commercial purposes, it is important to find that right product that will suit your requirements.

There are several important factors to consider before buying a tool and these are motor power, disc size, rpm, arbor size, and power source to name a few. Here are a few factors to consider:

Things to Consider Before Buying an Angle Grinder

Size of the grinder

Size is an important factor to consider when buying an angle grinder. The big-sized grinders are good for handling the heavy-duty jobs. The grinder’s size is usually determined by disc and not the length of the machine. The big-sized grinders come with large wheels so they are good for professional-grade jobs.

The small-sized grinders are capable of spinning at a much faster rate hence they are efficient in cutting and polishing metal. You can choose your grinder, big or small, depending upon the type of job you prefer.

Disc size

The discs also come in a variety of sizes so it is important to choose the right one for your job. The large-sized disc gives more power to the machine and they are suitable for heavy-duty jobs. The grinders with smaller discs are used for jobs that require a lot of precision such as tile cutting.

Motor power and performance

The motor power is determined by the wattage, voltage and amp rating, and these factors widely vary between the grinders. The grinders with high power motor are mostly used for the heavy-duty construction site jobs.

Motor power and speed

The voltage, wattage and amp rating vary between grinders. Many of the people will prefer buying a machine with a power ranging from 110 to 230 volts AC, and the wattage range from 500 to 2500 watts.

The speed with which the disc rotates is also of utmost importance and a typical handheld grinder will give you approximately 5,000 to 10,000 revolutions per minute.

Final Verdict

Whether you are looking for an angle grinder to take care of those small house jobs that get neglected due to the lack of a proper tool or you need it for your business use, finding the right angle grinder is important.

We would recommend that you opt for brands that you can trust because companies that have been manufacturing power tools for years are the ones who are above the learning curve.

The high-quality grinders from reputed manufacturers come with added advantages that you would not find in a locally made product.

When buying an angle grinder or any power tool, there are three important things that you must consider and these are ease of use, performance and safety features.

Apart from ease of use and good performance, you must also ensure that the product includes safety features for the operator’s well-being.

When using an angle grinder at home or commercial site, always make sure that you wear protective gear such as helmets, gloves, and eyeglasses to keep yourself safe from any accidental damage caused by flying dust or debris.
