Buyer Guide to Choose Bench Grinder

Power

The bench grinder can be placed in workshops or professional laboratories, but at the same time, it is also suitable for hobbyists with a little space available.

Depending on the needs, the wattage of the model must be assessed, and given that based on this, it will be possible to work with more or less efficacy on some types of metal.

If you are looking for a grinding wheel for polishing bolts or sharpening blades, it may be excessive to buy one that is too powerful because you could risk not making the most of it and considerably raising the costs on your end-of-month bill.

For hobby work, a 150 w grinding wheel is fine, more than enough for sporadic or non-intensive use. Otherwise, you will have to opt for a product that reaches 350 w to be able to use it continuously without fear of melting the engine.

Materials

Since these are objects designed to work metal, the bench wheels must necessarily be built with solid and long-lasting materials.

For this reason, we strongly recommend choosing a very resistant one, especially if you want to make professional use of it.

Good materials will also give stability to the tool, a significant factor since otherwise, it could vibrate to the point of making sharpening and grinding operations difficult.

For this reason, a decent bench grinder must have a certain weight, because if too light, the rubber feet may struggle to keep it firmly on the surface.

For your safety, we recommend checking that the grinding wheel to be purchased has PVC flaps for protection against sparks. If you do not have them, you will have to buy glasses or a protective mask to avoid injuries.

Assembly and Equipment

It is assumed that hobbyists or professionals looking for a grinding wheel is equipped with a particular skill and are not afraid of “do it yourself” assembly. Still, otherwise, they will be able to breathe a sigh of relief as the models in the ranking will be delivered in part already mounted.

This saves a lot of headaches and wasted time, also because let’s face it: often, the assembly instructions of the tools are not the best of life.

You will only have to install the discs and maybe the PVC flaps for protection. Speaking of disks, we suggest checking if these are included.

Usually, in the package, you will find a GR60 disk and a GR12 to be able to mill, grind or finish the materials.

Hoping to have clarified, we leave readers to review the products selected by us based on the positive opinions of users and their quality-price.

Compact and Powerful

The grinder has a compact design that offers a minimum size, of only 39.5 x 26.5 x 33.3 cm, and is powered by a 550 Watt electric motor, capable of generating a maximum speed of 2850 rpm per minute.

It is designed to work with standard discs with a diameter of 205 mm and is equipped with double splinter guards, one of which has a handy magnifying glass, and two bulbs to illuminate the work area.

It is sold with standard equipment consisting of two original Makita discs, a GR60 for roughing and a GR120 for finishing. At the same time, the multilingual user manual, including Italian, is available online on the Makita website, in format PDF, downloadable for free from the product page.

Beware of Replacement Discs

The only thing to pay attention to is the diameter of the engagement hole, which is 15.88 millimetres. In comparison, the non-original replacement discs that are on the market have standard drilling of 16 millimetres.

So there are two solutions, or only original Makita discs are used, which are a bit more expensive than the non-original ones but offer far better yield, or you need to apply a reduction of about 0.12 millimetres to standard discs, to adapt them to Makita grafts.

How to use a bench grinder

The bench grinding wheel is a powerful tool that allows you to smooth, eliminate the imperfections that a piece can present and many other things.

We will talk about the bench grinder, but the reader must know that the axial and angular grinding wheels are also available. But to return to the object of our guide, let’s see what the main features are. For this purpose, we refer you to the next paragraph.

The Characteristics of The Bench Grinding Wheel

This machine is equipped with an electric motor and is fixed on a bench. At the ends of the grinding wheel, there are two discs which, depending on the needs, can be made with abrasive material, an abrasive disc that works in pairs with a metal brush or a polishing cloth.

The Position of The Piece

When carrying out the quality of the piece, it is necessary to be clear about a series of points whose neglect could also have unpleasant consequences in terms of safety. First of all, make sure that the piece is well fixed, then not too much pressure must be exerted on the disc.

If you have mounted a deburring disc, do not dream of cutting and always keep a 90 ° angle between the workpiece and the disc. Remember to wear all the necessary protections, starting with those for the eyes and hands.

How to Mount the Disc?

First, you need a quick inspection of the disk to be mounted to make sure it is not damaged. Check that the protection cap of the bench grinding wheel is well installed.

When changing the disc, use the tools supplied by the manufacturer of the bench grinding wheel. Check the correspondence between the rotation speed (RPM) of the machine and that of the disc.

In any case, that of the machine must never be higher than that of the disk. Never lock the disc too tight.

What Not to Do with Discs?

The discs must be handled with due care and stored in a dry environment and at neither too rigid nor too high temperatures. Even with minimal damage, the discs must not be mounted as the disc rotation speed must never be exceeded.
