What is a Bench Grinder?

A bench grinder is one in a line of power tools, such as angle grinders and rotary tools, that are used to grind metals, woods, plastics, and other materials. Since metal is a strong and durable material, it takes a special tool to grind away rough edges or sharpen an edge on a tool. This is what a grinder is for. These are designed to sit on a bench or table as you grind, and it features grinding wheels with abrasive edges on either side.

These tools are frequently found in metalworking shops to grind, polish, and sharpen different types of metal including aluminum, steel, brass, and copper.

What are the Advantages of Owning This Tool?

Anyone that works with metal will find that owning a bench grinder is a necessity for smoothing rough edges or imperfect welds. While tools like a chop saw can be used, a grinder is more efficient and more precise for correcting imperfections in metal.

Even those who don’t frequently work with metal can benefit from adding one of these tools to their garage or workshop, as these can be used for sharpening metal and renewing old, dull metal tools and keeping knives sharp, saving money in replacement costs.

What are the Different Types?

Before investing in an expensive power tool like a grinder, you need to know what to look for to ensure you get the right product that will fit your needs. You don’t want to blow your money on something that you won’t ever use, so the first step to making a smart and informed purchase is to know about the types of grinders available and the differences between them.


These tools are used along with a bench to grind down metals safely and easily. These are portable, so they can be moved from place to place as needed.


These are very similar to traditional models. However, the main difference is that these are mounted to a pedestal, which is then bolted to a floor. These are not portable, but they are very sturdy and stable.


These are most often what is found in metalworking shops and other industrial areas. These grind just like other grinders, but they are designed to be larger, sturdier, and more heavy-duty than other types.

Features to Consider

Whether you’re replacing an old, dated grinder that just doesn’t get the job done or you’d like to add one to your garage or workshop, you have to know what you’re looking for before you make your purchase. A failure to plan and know what to look for in a new tool results in purchasing something that doesn’t fit your needs or exceeds your budget. Since you want to get the most use out of your new tool, make sure you pick the right one the first time by keeping an eye out for these four features.


Grinders made for household and general use may cost around $100, while industrial machines can easily run up to $1,000 or more. Price should be considered for two reasons. You want to set a budget and stick to it, but you don’t want to make a purchase solely based on price. If you need an industrial grinder, you’re not going to be able to buy the cheapest one on the market. Balance your budget with your needs and other important features before you make your purchase.


Any type of power tool is bound to have issues after years of heavy use. However, it isn’t unreasonable to expect your grinder to work right out of the box, and you also shouldn’t have to worry about parts failing after just a few uses. If your product has a defect that renders it useless after you’ve used it just a few times, a warranty gets the repair, replacement, or refund you deserve.

Stone Size

Larger grindstones can handle more heavy-duty jobs, while smaller stones are fine for household knife and tool sharpening. Make sure that you purchase a grinder with a stone that is the right size for the jobs you want to perform.
