Cordless Anger Grinder

Cordless  angle grinder,also know as a grinder or disc grinder,is a handheld power tool used for grinding(abrasive cutting),polishing,cutting and sanding. Although developed originally as tools for rigid abrasive discs,the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.

The common models of angle grinders are divided into 100 mm (4 inches), 125 mm (5 inches), 150 mm (6 inches), 180 mm (7 inches) and 230 mm (9 inches) according to the accessories used. The small size angle grinder used was 115 mm.If divided by power source,we have electric anger grinder and cordless anger grinder.

WORKING PRINCIPLE FOR CORDLESS ANGLE GRINDER

Cordless angler grinder usually with Brushless angle grinders, are angle grinders that do not use carbon brushes. Traditional angle grinders generally use carbon brushes and commutators to achieve motor current commutation. It is very troublesome to replace the carbon brushes according to the wear conditions of the carbon brushes, while the brushless angle grinders do not use carbon brushes, which reduces the need to replace carbon brushes. The trouble of brushing and the harm caused by carbon brush powder can also save costs and improve the service life of the machine;

THE ADVANTAGE BRUSHLESS ANGLE GRINDER COMPARE TO BRUSHED ANGLE GRINDER

✔ Automatic speed adjustment

✔ Supply a longer overall life

✔ Higher output power

✔ No need to replace carbon brushes for life

✔ Energy saving

✔ Smooth operation and low noise

✔ Brushless motor with low interference

BASIC KNOWLEDGE OF THE CORDLESS TOOLS

1. Common lithium-ion tools include but are not limited to the following products:

2. Basic knowledge of Li-ion products-Battery

Battery is the most important part of Li-ion products.The battery pack of lithium electric tools is usually composed of 18650 cells (18650 naming method: diameter 18mm, length 65mm, cylindrical)

A battery pack consists of 2-6 cells, the rated voltage of each cell is 3.6v, and the maximum voltage is 4-4.2v

Connecting multiple cells in series will increase the voltage, so there will be different expressions according to regional habits

Take the 18v battery pack (5 cells) as an example, European/Japanese customers are used to calling it 18v Central Asia/Southeast Asia

Customers are accustomed to calling it 21v MAX, and American customers have 18-20v different ways of calling, according to the customer and the expression is different and flexible switching.

10.8v = 12v 14.4v = 16v Max (may be false to 18 in Southeast Asia) 18v = 20v max = 21v max.

Generally, the battery pack capacity of 5 series cells is between 1.3AH-2.6Ah. If another 5 cells are added to form a parallel circuit.

Then the capacity is doubled between 2.6Ah-5.2Ah, and even a battery pack composed of 15 cells has a capacity of more than 6.0Ah

The mainstream capacity of batteries used in power tools is 1.3Ah/1.5Ah/2.0Ah, 2.0Ah can be converted into 2000mAh.

Common battery packs are divided into in-line and flat-push types. They are designed to consider the needs of different customers. Generally speaking, East Asian customers prefer in-line type, while European and American customers prefer flat-push type. Flat-push battery packs can be connected in parallel to increase capacity.

In-line battery pack example (7.2-24v)

Flat push battery pack example (12-24v)

3. Basic knowledge of Li-ion products-Charger

Because of its working characteristics, lithium batteries must be equipped with a control board and a corresponding charger.

Chargers are divided into two categories according to the charging plug style: 1. Wall plug type 2. Stand charging type.

4. Basic knowledge of Li-ion products-Motor/Control Board

The motors of lithium battery/DC tools are divided into 2 different kinds according to their working principles: brushed/brushless motors

Brushed motors are the most widely used, with low cost and uniform specifications, and are widely used in entry/light duty power tools

Brushless motors are mostly used for heavy-duty/high-end tools. Because they must be matched with a control board to work properly, they are bulky, and many small-sized tools cannot be used, which will also increase costs.

Control panel:

Lithium batteries must be used with a control board to provide functions such as overheat protection/overshoot protection/ over-discharge protection/short circuit protection. International brand products mostly use tools built-in over-discharge protection, chargers built-in overshoot protection, and circuit boards provide overheating protection /Short circuit protection to avoid some patent issues.

How to maintain an angle grinder ?

1.Clean the tool often.

2.Inspect the carbon brushes occasionally.

3.Check the state of the ON/OFF switch.

4.Use the correct attachment.

5.Inspect the power supply cord and auxiliary handle.

6.Inspect the gearbox occasionally.

7.Solve issues of overheating.

8.Do not apply any pressure on the tool when on load.

Can you put a blade on an angle grinder?

First, keep always use the right blade for the job... You can buy several types of blades for an angle grinder, depending on what material you are cutting. The most common materials are wood, concrete, and metal. Always use the right blade, to help avoid personal injury, and replace it when it is worn out.

Do plumbers use angle grinders?

The rapidly rotating disc on an angle grinder doesn't just smooth, polish, and grind away metal, it can also be used for cutting through metal. This is a common use for plumbers who are working with galvanized iron or lead pipes.

What safety tips should be known before using an angle grinder?

Angle Grinder Safety

Angle grinders combine two dangerous elements together, a high RPM spinning motor with a sharp cutting disc. The following safety tips should always be considered to help avoid serious injury:

Ensure the device is switched off before you plug it in. Before plugging an angle grinder into the power source, make sure that the machine itself is switched off.

Read the manual and understand how it works. Even for an experienced user when getting a new power tool it is always a good idea to read the manual to ensure that you are completely familiar with the modes of operation and the features of the tool. Power tools are inherently dangerous machines, so this is very important...
