Out of the various power tools available on the market, few come in as many types as grinders.
Grinders are machines used for, you guessed it, grinding. They can cut and shape any metals and also polish their surface. All of the grinder types use wheels with an abrasive finish to do the job. There are over 10 different types of grinders but the most common ones are as follows:
An angle grinder is a hand-held device that is commonly used by both professionals and amateurs. Its build makes it a handy tool for any construction work, you can use it to easily cut through pipes or shape tiles. An angle grinder usually has detachable wheels that can be switched out for many other different attachments. This makes it so versatile. This multi-purpose tool is the most common type of grinder.
If you need one for professional reasons you will need to get one that has been certified safe to use at heavy-duty jobs. But if you are just looking for something to help you with home renovations than any quality brand will do. You can buy one at most home improvement retails stores.
A bench grinder is a stand-alone tool that is often attached or bolted down in some way to a table or a workbench. It has two abrasive wheels that have different grains. Bench grinders are mainly used for polishing and finishing off the surface of various metals. They can also sharpen other tools or even shape some simple wood projects. You might need to purchase additional wheels depending on the type of job you want to do.
Bench grinders are more often used by professionals although some people with a large workshop at their home also choose to purchase them. There are many models available but one of the most often recommended ones are the models from Porter Cable. A Porter Cable Bench Grinder is a reliable machine that will complete the job efficiently in any kind of setting.
A floor grinder is a machine resembling a large and round vacuum cleaner and its primary use is grinding floor surfaces. The abrasive wheel has a large diameter so it can go through large areas fairly quickly. This type of grinder is used to wear down most floor surfaces including wood, concrete, or tiles. Any unevenness can be taken down using a floor grinder which makes them the perfect tool for maintaining commercial lots.
They are most often used by professionals and it is relatively rare to see somebody buy one for personal reasons. If you need to have the floor at your home grinded, many companies offer rental services. In most cases, it will be easier to just rent one out every few years than buying another big power tool just for your floors.
