Before getting to a point of selecting one small angle grinder as the best one for your projects, it would be beneficial to learn what an angle grinder is in more general terms. Angle grinders, also known as side or disc grinders, are portable power equipment used for grinding and polishing. They’re utilized in a wide range of sectors and vocations, including metallurgy, construction, and emergency rescue.

An electric motor, a gasoline engine, or compressed air can all be used to power the angle grinder – or in this case the small angle grinder. For practical purposes, the portable angle grinder is the most widely used and recognized type. Cutting discs having a diameter of up to 115 mm are used in small angle grinders. They’re great for cutting metal, but they rapidly run out of steam when it comes to concrete.

When purchasing a small angle grinder, or bigger kinds, keep the following aspects in mind:

Angle Grinders of Various Types

Angle grinders are divided into three main categories, each with its own set of applications. To make an informed purchasing selection, it’s critical to grasp the distinctions between each variety.

Cordless Angle Grinders

Angle grinders with cordless power are utilized in a wide range of applications. These grinders may be moved from one location to another without needing to be connected to a power source. When it comes to doing ladder and scaffold-based grinding jobs, cordless grinders are especially useful because there are no trailing wires to provide a trip hazard. To eliminate the worry of a regular mains power connection, it is recommended to pick models with large capacity batteries.

Corded Angle Grinders

In some cases, the guarantee of a dependable power outlet will be necessary, as corded angle grinders can be used as long as they are linked to the power source. Small angle grinders that are corded are generally less in weight than cordless versions. If you’re planning to use your grinder for modest cutting chores on a regular basis, get one with a tiny disc. You should also consider the ergonomics and vibration level of the grinder you’ve picked.

Pneumatic Angle Grinders

Pneumatic angle grinders are suitable for cutting and shaping metal workpieces because they combine performance and durability. This type of small angle grinders is mostly utilized for light-duty operations that need a lot of accuracy. Pneumatic grinders need the use of an air compressor, but they are well-suited to high-precision applications and are far lighter than conventional angle grinder models. Furthermore, some come equipped with throttle levers, allowing for precise control while doing specialized chores like feather edging and speed grinding.

Depending on the discs attached, here’s a summary of the most typical uses for air angle grinders:

  • Grinding: Using moderate pressure at an angle, the material will be smoothed to perfection. Surface preparation and material removal are among the activities included.
  • Cutting: For precise pipe or metal cutting, smaller wheels are utilized.
  • Angle grinders are excellent for sanding woodwork.
  • Deburring: Air grinders can quickly remove pestilent burrs or material remnants.
  • Chamfering: wheels may be used to create bevels and grooves as well.
  • Angle grinders are also used to remove welded connections and smooth them out.

Angle Grinder Sizes

The size of the angle grinder is defined by the size of the disc, not the tool’s length. Smaller discs spin more quicker and produce a clean incision in the surface.

Grinder discs with a diameter of 12 cm are the most frequent. It may be used for modest projects such as cutting wood or metal up to 2-3 cm thick. It is not advised to use a small angle grinder to cut stones or concrete.

Small pieces of wood, thin metal, and aluminum that are 4-5cm thick can be utilized with the 18cm discs. Larger chunks of any material up to 7-8cm thick can be cut with the 23 cm discs.

What to Look for in a Small Angle Grinder

small angle grinders can usually hold a disc that are seven inches in diameter or smaller. They’re found on a number of angle grinders and may be utilized for a variety of cutting and grinding tasks. The 4″ and 4 12″ sizes are the most popular. These grinders can generally handle wheels up to 7 inches in diameter, with smaller models able to handle 3 inches discs.

The small angle grinders should ideally feature a brushless motor, which eliminates the need to change brushes on a regular basis. The cordless model’s brushless motor will also allow for efficient operation, reducing heat build-up and ensuring that the tool lasts for a longer length of time.

The kick back brake is an important safety element that ensures the wheel of any small angle grinder stops immediately if it becomes stuck. This will keep the instrument from falling loose and inflicting significant harm. Some angle grinders also have two-stage triggers, which need the safety switch to be turned off before the trigger may activate the tool. This reduces the possibility of unintentional starts while changing CDs.

Use of a Small Angle Grinder

Small angle grinders -just like any other angle grinder- function by attaching a range of replaceable abrasive discs or blades to a fast-revolving headpiece. The rapid rotation makes these instruments very strong, allowing them to cut through even the toughest materials such as metal, concrete, and stone. Smaller grinders, on the other hand, can be used for more delicate tasks like cutting ceramic tiles or polishing metal.

A small angle grinder can be used to grind away burrs left after cutting metal using different power saws, in addition to cutting the materials listed above. Grinders may also be used to remove rust and grime from metal, as well as polish it. This multi-purpose tool can even remove paint and sharpen instruments.

Angle grinders can be used with a variety of attachments, including diamond-bladed cutting discs for tile cutting, abrasive discs for sanding, grinding, and polishing, and cleaning wire brushes. Angle grinders are strong and quick instruments. When using a small angle grinder, exercise extreme caution and always wear protective equipment, including safety glasses.
