How to choose your grinder 230 mm

To give you a chance to acquire the best 230mm grinder, these few criteria should be considered before purchase.

#1 - Motor power

The motor is the heart of this power tool. It is imperative that it is powerful enough for you to work efficiently. The machine power of 230 mm angle grinders varies from 2000 W to 2600 W. Although it is up to you to choose the power that best suits your personal or professional activities, a 2200 W machine will allow you to do all the work involved in a construction or demolition site with great ease.

#2 - Power supply

You will have to choose between two types of angle grinders, namely the corded model and the cordless model. The corded angle grinder has power to spare. It is the must-have for large jobs. However, this model cannot match the cordless models in terms of portability and flexibility of movement. Besides, technological advances in recent years mean that the batteries in 230mm angle grinders offer more and more autonomy.

#3 - Ergonomics

A 230mm angle grinder should be ergonomic and convenient to use. For regular use, the comfort level should be high enough. You must therefore pay attention to the elements that ensure a good grip of the device, as it is the case of removable handles, thanks to which you will be able to work in multiple positions. Knowing that the comfort of use is of poor quality on devices subject to strong vibrations, prefer a model that perfectly absorbs the sensations of hammering.

#4 - Ease of maintenance

As working with this tool is already quite tiring, prefer a 230 mm angle grinder that is easy to maintain. This will save you from spending hours cleaning the unit, an operation that you will actually do again after the next use. Remember, regular cleaning is the only way to keep the power and performance level of the unit at its peak.

#5 - Safety options

Never compromise on the safety options offered by a 230mm grinder. Remember that this device is still dangerous, especially when in the hands of an inexperienced person. So, see if the tool has a protective cover that should cover at least half the surface of the disc. This will act as a shield against splashes, sparks and even a possible disc break. The device must also be equipped with a dead man's switch and a soft start function.

How to recognize a 230 mm grinder and what makes it special?

Weighing an average of 5 kilos and with a powerful motor of 2000 W to 2600 W, the 230 mm grinder can easily work on all types of heavy duty materials that are known to be very resistant.

This power tool is easily recognized by its rotation axis which forms a right angle with the machine. It is from this mechanical feature that it gets its name of angle grinder. Thus positioned, the 230 mm grinder is more versatile. It can be used for a variety of jobs, especially since its disc can be switched with other elements in a few seconds. Construction professionals especially appreciate its high capacity to grind and cut high carbon steel.

Equipped with a thick disc adapted to the material to be worked, this equipment can be used for deburring, surfacing, stripping relatively thick sheets. It can also be used to adjust profiles or to surface chamfers and large steel tubes. The cutting depth of a 230 mm grinder is a maximum of 70 mm, which is enormous.

Equipped with a diamond disc or a thin abrasive disc, the powerful angle grinder easily cuts rebar, U or I sections, metal rods and steel bars up to 30 mm in diameter. When it comes to dismantling or deconstructing metal assemblies and structural materials such as bricks and cinder blocks, there is no better tool than the 230 mm diameter angle grinder.

An angle grinder can be used for hours without the risk of overheating its motor. As soon as it is switched on, a turbine actively cools all its components. Openings at the rear of the housing draw in fresh air before directing it to vents at the front. Despite this ingenious cooling system, the unit should be properly cleaned after each use.

Pay attention to your safety!

There's no denying that using a 230 mm grinder is exhausting because of its weight. To avoid accidents, take short breaks every 2 hours. Another thing, the protective cover is insufficient against projections. So, wear gloves, goggles, earplugs and a helmet when you work.

The different types of grinders 230 mm

230 mm angle grinders are distinguished by the way they are powered. Also, you will have to choose between the 230 mm corded grinder and the 230 mm cordless grinder.

The 230 mm corded grinder

The 230 mm grinder is widely used in physical shops and on the internet. It is especially appreciated for its powerful motor that allows it to work on all building materials made of steel, metal, marble and concrete. The question of autonomy does not arise with this category of devices because it is permanently supplied with energy via an electrical socket.

Advantages: Once connected to the mains, you can get straight down to work. This device will allow you to be more efficient, because your attention will not be diverted by the constraints of the autonomy.

Disadvantages: The corded grinder must always be connected to an outlet, which is a major drawback. Its use is also limited by the length of the cable. For work at height, the corded model is not very practical.

Who is it for? The 230 mm corded grinder is perfect for anyone who needs a device that combines power and performance. This tool will be very useful for construction workers, experienced do-it-yourselfers, and iron artists.

The 230 mm cordless grinder

The 230mm cordless grinder is a fairly recent invention. It was designed to meet the mobility needs of construction workers. The self-contained battery offers the advantage of unconstrained use in locations away from power outlets. Rest assured, the grinders are as powerful as corded grinders.

Benefits: The 230mm cordless grinder is ideal for precision work at height. It will allow experienced users to perform a multitude of jobs in unconventional high places.

Disadvantages: In addition to its clearly limited battery life, the cordless grinder is difficult to handle, as the battery adds extra weight to the package.

Who is it for? The 230mm cordless grinder will be useful for people who need to do precision work outdoors or at height. It is also recommended for handymen and metalworkers.

230 mm grinder or 125 mm grinder?

Grinder 230 mm

The 230 mm grinder is heavy and very powerful. Its large discs can cut bricks, tiles, marble, concrete, as well as metal bars and steel sheets. This equipment is also very much in demand for making grooves in freshly built walls. It is mainly used for structural work, but also for all kinds of DIY work and iron works of art.

Grinder 125 mm

The 125 mm grinder is mainly used for grinding and cutting thin metal materials. It is also used for polishing, sanding and stripping of all kinds of building materials. In contrast to a 230 mm grinder, a 125 mm grinder is lighter, which makes it easier to handle.


For purely recreational use, a 125 mm grinder is best, as it can still cut thin steel bars. If you are an experienced DIYer, ironworker or construction worker, consider a larger, but more powerful 230 mm grinder.

Why invest in a 230 mm grinder?

It is versatile

The 230 mm grinder can be used for a multitude of jobs. Cutting, cutting off, brushing, polishing, filing... you can do it all as long as you have the right discs. On a construction site or at home, the grinder will always be very useful, especially since it is quite easy to handle despite its weight.

It is easy to handle

Whether it is powered by an electric wire or a battery, a 230 mm grinder is still a very pleasant tool to handle. Beginning handymen will not need more than a week to master the basics. For practical and safety reasons, just make sure the unit is equipped with a second handle and a protective cover.

It is effective

When equipped with the proper disc, the 230mm grinder is capable of cutting or surfacing the toughest materials used in construction, metal work and hobby work. Concrete, iron, steel, metal, marble, stone, nothing can resist the power of this tool.

It can be adapted to your activities

The use of a grinder stand will allow you to perform precise work, such as cutting a metal pipe with a chain or mitering a wooden profile for example. This ingenious stand turns your portable grinder into a stationary cutter. If you want to use the 230 mm grinder outside, simply remove it from the stand.

It is easy to maintain

You can find 230 mm grinders at all prices on the market. Nevertheless, refrain from buying excessively low-cost products, as they will need extensive maintenance after each use. This will wear you out in the long run. With a model from a reputable brand, maintenance will be a breeze.

Add the protective housing

Maintain your 230 mm grinder

Maintaining a 230 mm angle grinder is not difficult. To dislodge dust that has accumulated inside the unit, use a mechanical blower. If you don't have one, you have to do it manually. A cloth soaked in alcohol is recommended for a thorough cleaning. Don't forget to lubricate the ball bearings, drive shafts and the disc with mineral grease, preferably.


How to orientate the protection cover of a 230 mm grinder?

The protective cover can be adjusted manually. To do so, simply loosen the flange with a wrench and make the necessary adjustments.

Cleaning a 230mm grinder should be done after each use. Before storing it in your toolbox, dust it with a power blower if you have one. Otherwise, clean it with an alcohol-soaked cloth. To optimize the unit's longevity, don't forget to lubricate its metal parts with mineral grease, like the ball bearing and drive shaft.

How to use a 230 mm grinder properly?

Finding the best working angle between you and your machine is the secret to using a 230mm grinder well. This will help you work comfortably, and not get splatter.
