Are you a professional handyman residing in Ghana? Or are you one of the Do-It-Yourself (DIY) kinds of a person with an interest in doing some small or big-time constructions around your house?
One tool is sacrosanct whether you are any of these categories of persons. It is the Angle Grinder.
Professional handymen and ambitious DIYers alike consider this a must-have power tool.
The Angle Grinder is a portable, flexible power tool that is used to cut, grind, deburr, finish, and polish a variety of challenging materials, including iron, copper, brass, brick, tile, stone, mortar, paving stone, metal, and concrete, with their high-speed revolving disc.
Angle grinders, also known as side grinders or disc grinders, are becoming increasingly popular in homes and workplaces, as well as in industries such as metalworking, construction, and emergency response.
WHY YOU SHOULD OWN AN ANGLE GRINDER
Angle grinders typically have three basic functions; cutting, grinding, and polishing. In terms of cutting they run at a high speed and facilitate cutting tasks with ease as well as giving better precision in terms of grinding than stationary grinders as they are handheld.
They can then be used, providing you have the right attachments, to restore scratched metal and polish it. If you’re looking to hire an angle grinder, you may want to take a look at the multitude of ways they can help you.
As such a versatile piece of equipment angle grinders have a plethora of uses.
- Paint Removal: Auto body shops often use an angle grinder as a method of removing paint. This is because an angle grinder is able to remove old paint without damaging the metal underneath.
- Rust removal: Rust can also be removed using an angle grinder. Using a wire wheel or brush attachment can remove a layer of rust and prepare the surface for paint. They too also help to preserve the healthy metal underneath.
- Ceramic Tiles Cutting: Angle grinders are great for cutting things such as ceramic tiles. They work great as they leave a clean, crisp edge to the tile and work similar to a wet tile saw.
- Mortar Peeling: Removing mortar with an angle grinder tends to be quicker and easier than chiseling. Using an angle grinder also makes it less likely that you’ll chip the bricks whilst cleaning out mortar from between them.
- Stone Cutting: As an angle grinder is able to make nice, smooth cuts it makes a good choice for stone cutting. For extra mobility use a smaller grinder which will be able to easily make smaller, precise cuts.
- Metal Cleaning: As with clearing rust from cars, angle grinders can also be used to clear rust and clean metals. Using a wire brush, you can easily clean metals such as shovels and tools.
- Metal Cutting: As well as cleaning metal, angle grinders are also great for cutting metal. Angle grinders are compatible with all metals and generally cutting metals is classed as ‘intended use’ for an angle grinder so they perform well.
- Tools Sharpening: Angle grinders can be used as an alternative to a bench grinder when it comes to tool sharpening, however, to do this you will need to be sure you are extremely skilled in controlling the grinder, and ensure you know what you’re doing.
- Wood Carving: You can use carving discs to carve larger wooden objects effectively. Angle grinders are great for rough shaping; for example, making tables or table legs. However, they are not fine enough to do intricate woodwork.
- Wood Planning: Similar to the carving disc, you can also use a carving wheel to plane wood. An alternative to a wood plane, the carving wheel can be used for various planning tasks.
ALL YOU SHOULD KNOW ABOUT TYPES AND SHADES OF ANGLE GRINDERS
Here’s a rundown of the various types of angle grinders and their applications. Anyone looking to get the most out of an angle grinder and increase efficiency and production should familiarize themselves with the various varieties and how they work.
Angle grinders are classified into three categories: corded angle grinders, cordless angle grinders, and air-powered/pneumatic angle grinders. Others include, but are not limited to, Variable Speed Angle Grinders, and Straight Angle Grinders, as technology advances in how this power tool can best serve consumers.
Corded Angle Grinder:
These tools connect to an outlet for longer run periods than cordless tools, making them ideal for repetitive operations and applications where portability isn’t an issue. They operate at full power and do not require recharging of batteries.
A corded grinder may be ideal for a workshop, but it can be problematic in the field or on site because of supply of energy.
They are further divided into the following categories:
- Standard Head Corded Angle Grinders with Barrel Grip
- Standard Head Corded Angle Grinders with Rat-Tail Grip
- Flat Head Corded Angle Grinders with Barrel Grip
- Flat Head Corded Angle Grinders with Rat-Tail Grip
- Fillet Weld Corded Angle Grinders with Barrel Grip
Cordless Angle Grinders:
Professionals are increasingly flocking to cordless power tools because of their capacity to operate independently from a continuous power source.
Cordless grinders are a great option for short projects or specific cutting or grinding tasks. Whether you’re working with metal, stone, or ceramic, a cordless angle grinder allows you to grind and cut even the toughest materials without the use of cumbersome cords.
These versions have an obvious advantage in terms of simplicity of usage. You won’t have to deal with extension cables, and you won’t have to worry about cutting the cable while using it.
Air Powered/Pneumatic Angle Grinders:
These tool uses air power to rotate grinding wheels to remove surface material or cut-off wheels to cut through it. They are capable of removing material in a variety of ways, from sanding with a flap wheel to heavy-duty removal using grinding wheels. A proper cutting disc can be used to cut a wide range of materials (including diamond coated).
Variable Speed Angle Grinders:
Angle grinders with variable speed control are less common, but they can provide the operator a lot more control and are worth considering if you plan to use the tool for more than just cutting and grinding.
A speed control function is included, as well as a speed rating plate that displays the maximum operating speed in RPM.
Straight Angle Grinders:
Straight angle grinders are meticulously cataloged to ensure optimal efficiency. All grinders are made with the highest-quality DeWalt materials and motors, making them extremely long-lasting. When professional workers need to increase access, comfort, and control over daily duties in the field, they turn to these grinders, with different grinding stones attached; the straight angle grinder’s wheel is positioned at a 90-degree angle, making it a perfect tool for polishing outer edges and inside parts of components.
WHAT TO CONSIDER BEFORE BUYING AN ANGLE GRINDER
With your interest in the A-Grinder, the need to understand the distinctions becomes necessary.
One sterling attribute of the Angle grinders is that they can be powered by an electric motor (an electrical machine that converts electrical energy into mechanical energy), a petrol engine, or a gasoline engine (an internal combustion engine with spark-ignition designed to run on petrol and similar volatile fuels), or compressed air (an important medium for energy transfer in industrial processes, and is used for power tools such as air hammers, drills, wrenches, and others).
These tools can run on batteries or be directly linked to the engine through a power cord to provide a steady supply of electricity.
Angle grinder discs come in a variety of sizes and types, and they are interchangeable, so you can choose the right size for your grinder and the right type of disc for the material you want to cut or grind. The disc size has a direct impact on angle grinder selection. 4.5″ (115mm) and 9″ (230mm) are the most frequent disc sizes. Larger disc grinders are more suited to heavy-duty applications, whilst smaller disc grinders are better suited to lighter-duty applications.
The following factors are to be considered when buying the best angle grinder. There are many different sorts of grinders to choose from, and they come in a variety of shapes, sizes, and weights.
- Dimensions of the Disc.
- The power of the motor.
- Ratings for speed.
- The degree of comfort.
- Accessories and wheels

HOW TO OPERATE AN ANGLE GRINDER SAFELY
An angle grinder is an extremely powerful piece of equipment. They usually spin between 9000 and 11000 RPMs, inches away from your torso, face, and hands. If you operate an angle grinder incorrectly, this can cause serious injury to you or those around you.
As easily as this instrument can grind or cut through metal, it can cause more harm to the human body.
Respecting the equipment and its safety regulations is always the smartest and safest thing you can do for yourself and any bystanders you may encounter, regardless of whether you are alone or with others. If you’re going to use a grinder, keep the following safety suggestions in mind.
- Always Wear Proper PPE: Personal protective equipment, or “PPE,” is specialized clothing or equipment that is worn to protect users from health and safety hazards at work. Personal protective equipment includes items such as gloves, safety shoes, safety goggles, respirators, earplugs, and hard helmets.
- Use the Proper Wheel Size: Grinder wheel sizes are especially significant when considering the materials that will be used with them. The process of selecting the appropriate grinder wheel size is not as difficult as it may appear. Minor wheel grinders are appropriate for small applications because they have smaller discs and are lighter in weight. Bigger wheels make deeper cuts, so when deep cuts are required, a larger grinder, such as a 9-inch grinder, is required. This grinder’s blade is 4.5 inches long and extends from the center. Cuts to the skin, amputation of fingers, eye injuries, head injuries, and foot injuries can all result from using the wrong wheel angle grinder.
- Match the RPMs with your Wheel’s Allowance
- Use the Safety Guards as Designed
- Don’t Tinker with the Machine
- Inspect the Abrasives
- Warm Up & Inspect the Grinder
- Avoid Fire Hazards
- Tighten Discs Properly
- Maintain Control with Two Hands
HOW TO CHOOSE THE RIGHT ANGLE GRINDER
In any industrial application, selecting the right tool for the job is critical. The correct tool will increase operator efficiency, lowering the labor cost of producing a component. The correct tool can also improve operator ergonomics, reducing the risk of long-term injury.
The following factors must be considered while choosing the proper angle grinder for your material:
- What resources are available to run the tool, in terms of energy supply?
- How long will the operator utilize the tool on a daily basis?
- How much room is there for the tools?
- What are you using the angle grinder for, specifically?
- Buy power tools from the best store with affordable quality electric angle grinder
Small Angle Grinders
The disc size, not the tool length, determines the size of the small angle grinder. Smaller discs spin faster and leave a smooth cut on the surface. The most popular small grinder discs have a diameter of 12 cm. It’s suitable for little projects like cutting wood or metal up to 2-3 cm thick. Smaller variants can take discs up to 3 inches in diameter, while larger models can handle wheels up to 7 inches in diameter.
What to Look for in a Small Angle Grinder
The brushless motor in the small angle grinder is great since it eliminates the need to replace the brushes on a daily basis. The kickback brake is an important safety element that stops the wheel from spinning when it becomes stuck. This will prevent the instrument from becoming loose and causing significant damage. Some angle grinders have two-stage triggers that require the safety switch to be depressed before the trigger may fire. Unintentional disc alterations that result in a start are less likely as a result of this.
Medium and Large Angle Grinders
Angle grinders with 7′′ discs are considered medium-sized. When purchasing a medium-sized angle grinder, make sure it has a motor with at least 3 horsepower (3 HP). The ones with discs up to 9 inches fall into a large category, and motors with a capacity of more than 5 HP are projected.
Angle grinders in the medium-to-large size range are frequently corded. A medium-sized angle grinder should have a maximum speed of 8,000 RPM, while a bigger angle grinder should have a maximum speed of 6,000 RPM. The larger angle grinder, on the other hand, will have significantly more power.
WHAT TO KEEP IN MIND WHILE COMPARING ANGLE GRINDERS
When comparing angle grinders, there are a few things to keep in mind. Before you make your purchasing decision, read the following descriptions.
Angle Grinder Disc Size
When looking at angle grinders, you’ll need to figure out what size disc you’ll need. The two most typical sizes are 4.5″ (115mm) and 9″ (230mm). The depth of the cut is determined by the disc size, so larger jobs will necessitate larger discs. Smaller angle grinders often have a greater RPM than larger angle grinders, which implies small discs wear out faster than bigger discs. An angle grinder disc is sometimes known as a head or a wheel.
Power of the Grinder
The cutting or grinding ability of an angle grinder is determined by the machine’s power. The wattage, amp rating, and, in the case of cordless tools, voltage, all show the tool’s power. Angle grinders come in a variety of voltages, amp ratings, and wattages.
Power in does not always imply power out. When measuring the efficiency, power, and final value of a grinder, input power, or the amount of power a tool requires to function, might be deceiving. The output power, or the power utilized for tool operation after heat loss, is a more informative metric for determining a grinder’s performance level.
Speed of the Wheels and Discs
Angle grinders are a form of abrasive wheel. The maximum operating speed of abrasive tools refers to the maximum speed at which rotating abrasives can be operated when mounted to the appropriate grinders during use.
The user must closely adhere to the maximum operating speed mentioned on the abrasive for safety reasons. Angle grinders typically spin at speeds ranging from 2,000 to 13,000 revolutions per minute, with a medium-sized angle grinder producing around 8,000 RPM and a bigger angle grinder producing around 6,000 RPM.
Demand and supply (which includes product location in Ghana)
Angle grinder demand is on the rise as building and construction activities and the use of power tools expand. Because of the increased demand for consumer devices with more functionality, higher performance, and longer battery life, semiconductor manufacturers are focusing on finding faster ways to produce end-use goods. Power tools such as angle grinders are critical to achieving these objectives.
