Angle Grinder Buying Guide

Also known as side or disc grinders, angle grinders are portable power tools specifically designed for grinding and polishing. They are used across a variety of workplaces and industries including metalworking, construction, and emergency rescue.

Power to operate the angle grinder may be generated via an electric motor, petrol engine, or compressed air. The handheld angle grinder is the most commonly used and recognised model for practical applications.

The size of the disc should have a direct bearing on your choice of angle grinder. The two most common disc sizes are 4.5” (115mm) and 9” (230mm). Grinders with larger discs are particularly well suited to heavy-duty applications, whereas those with smaller discs are ideal for finer work. Additionally, it’s worth bearing in mind that smaller grinders have a relatively high RPM and smaller discs are also more prone to wearing down quite rapidly.

The following factors should be considered when buying an angle grinder:

  • Motor power

  • Power source

  • RPM

  • Arbor size

Different Types of Angle Grinders

There are three main types of angle grinders, each suitable for specific purposes. It is important to understand the differences between each type in order to make a well-informed buying decision.

Angle Grinder Types

Cordless Angle Grinders

Highly practical cordless angle grinders are used across a variety of worksites. These grinders can be transported to different areas without the need for connection to power outlets. Cordless grinders are particularly helpful when it comes to the performance of ladder and scaffold-based grinding tasks as users have no need to worry about the trip hazard posed by trailing wires. However, it is advised to choose models with high capacity batteries to avoid the concern of regular mains power connection.

  • Emergency rescue

How to Use an Angle Grinder Safely

Angle grinders typically incorporate a range of safety features for the effective prevention of injury. The slow start is one such feature, stopping the grinder from twisting immediately after being started. The anti-kickback is another valuable feature which ensures that the motor cuts out if the angle grinder gets caught up dangerously on any material. Restart protection will ensure that the angle grinder stays switched off in the event that it has overheated or cut out and been left with the power on. An additional safety feature is the paddle, or deadman’s switch, which ensures that the grinder only operates when held in two hands and prevents any spinning should the switch be released.

There are a variety of safety procedures which should be followed when using an angle grinder. To begin with, you should equip yourself with a complete set of personal protective equipment, including a dust mask, ear defenders, and safety goggles. The protective clothing should act as a safeguard against contact with any sparks that fly up when using the angle grinder. There should also be minimal risk of your clothes catching fire during operation.

It is expected that you will alert your co-workers and anybody else present on the worksite before you begin using an angle grinder. You should also take care to organise the wiring in order to prevent serious electrical incidents. The disc should be completely static before the angle grinder is positioned upon a surface to ensure that it doesn’t spin and cause significant damage.

These safety procedures should also be followed:

How to Choose the Right Angle Grinder

Most tasks requiring the use of angle grinders will be conducted over extended periods of time. It might be necessary to make repeated passes over the workpiece with a small handheld tool before application of the grinder. Durability will be one of the key factors and you must ensure that the appropriate amount of power is generated for the specific task at hand.

Small Angle Grinders

A small angle grinder typically has the capacity for a disc of seven inches or less. They can be used for a range of cutting and grinding purposes and are featured across a variety of angle grinders. The most commonly used sizes are the 4” and 4 ½”. These grinders typically have the capacity for wheel diameters of up to 7”, with particularly small versions having the capacity for 3” discs.

What to Look for in a Small Angle Grinder

Ideally, the small angle grinder will be fitted with a brushless motor, meaning that the brushes don’t have to be regularly replaced. The brushless motor will also allow for the efficient operation of the cordless model, minimising the build-up of heat and ensuring that the tool lasts for an extended period of time.

The kickback brake is an essential safety feature, ensuring that the wheel is stopped automatically in the event of binding. This will prevent the tool from coming free and causing serious damage. Some angle grinders are also fitted with two-stage triggers, meaning that the safety switch must be flicked to off before the trigger can set the tool into action. This minimises the risk of accidental starts associated with the changing of discs.

Medium and Large Angle Grinders

Angle grinders featuring 7” discs fall within the medium-size category, while those with discs between 7” and 9” are categorised as large. Large angle grinders are purpose-made for taking substantial cuts and scanning considerable surfaces in one pass. They also have particularly high levels of horsepower.

It is quite common for angle grinders in the medium-large size range to be corded. A good quality medium size angle grinder should include motors with a capacity of at least 3 horsepower (3 HP) while a large grinder would be expected to feature motors with a capacity in excess of 5 HP.

What to Look for in a Larger Angle Grinder

It is quite common for large angle grinders to feature overload protection, designed to prevent the grinder from breaking down under substantial weight. The auto shut off is another common feature which alerts you to the need for brush replacement to protect the motor. Some grinders also feature adjustable side handles which allow for a greater degree of flexibility and manoeuvrability. Additionally, there may be the option to fit a vacuum attachment for the effective collection of any dust and debris which is generated during operation of the angle grinder.

Comparing Angle Grinders

There is a selection of key factors to consider when comparing angle grinders. Read the following descriptions before proceeding to weigh up your buying choices.

Disc Size

The angle grinder disc may also be referred to as a head or wheel. There is a wide range of disc sizes available, but some of the most common sizes include 115mm (4 ½”) and 230mm (9”). The most appropriate choice of disc size will depend on the task that you want to carry out, however, you must ensure that the disc is compatible with your grinder.

Power of the Grinder

Angle grinder wattage (W) is specific to the amount of power which is generated. The required wattage level will depend on the size of the discs. The input power of a corded model will be rated in terms of amps (A), with the corresponding input for cordless models being rated in terms of volts (V). The input of pneumatic angle grinders is presented in terms of CFM (cubic feet per minute) and there is typically a corresponding pressure in pounds per square inch (PSI).

Speed of the Wheels and Discs

You should be aware that angle grinders with the capacity for small discs generate a higher RPM than larger models. It is common for the rotations per minute (RPM) to be expressed in terms of ‘no-load speed’, which is equivalent to the fastest rotation without a disc being installed. A medium-sized angle grinder is expected to go faster than 8,000 RPM, while a larger angle grinder may generate around 6,000 RPM. However, the larger angle grinder will have far more power.

Different Wheels and Disc Types

Silicon Carbide Grinding Discs

These discs are purpose made for the shaping of metals. They also allow for the efficient removal of materials and prevention of surface damage. Use of the grinding discs is expected to minimise the need for subsequent processing, allowing preparation time to be saved.

Cutoff Grinding Discs

These discs are purpose made to cut hard items and materials such as rods, bolts, rebars, and metal piping.

Sanding Pads and Discs

Sanding pads allow for the efficient removal of old paint in the process of surface preparation. They are also suitable for coarse and fine sanding.

Grinding Wheels and Discs

The grinding wheel is an expandable wheel, made from an abrasive compound. It allows for a variety of grinding and abrasion functions. Grinding wheels and other forms of bonded abrasives have two key features – the abrasive grains which allow for efficient cutting, and the bond which combines and supports the grains during the cutting process.

Grinding discs are suitable for metal and stone applications across a range of machine sizes. The main use of such discs is in the removal of materials. However, they can also be used for the finishing and preparation of stone and metal surfaces.

Wire Brush Wheels

These wheels allow for the effective removal of paint and rust. They also enable the removal of burrs from rough-cut metal surfaces.

Diamond Cutting Wheels and Discs

These wheels and discs are particularly suitable for the cutting of concrete, tile, masonry, and granite. However, it is important to make the appropriate selection and use of the cutting blade in accordance with the technique. There are diamond blades suitable for dry and wet cutting.

Aluminium Oxide Grinding Wheels

These oxide-based wheels are suitable for a wide range of applications, including woodworking and the cutting of crumbly materials like cutting boards.

Flap Discs and Wheels

The flap disc performs a similar function to the wire brush yet features flaps rather than wires. This allows for the effective combination of weld beads with the rest of the metal.
