Brushless Cordless Saw

Hello! I have been working in the field of Internet optimization for 10 years, and during this time I have seen many questions regarding power tools. And today we'll talk aboutbrushless cordless saws. Why them? Well, that's a different story - they are much more efficient, durable and convenient than their counterparts with brushed motors. But how to choose the perfect one? This will be our topic today.

Why have brushless cordless saws become popular?

If you've used older cordless saws with brushed motors before, you've probably had a frustrating experience. Quick breakage of brushes, the need to replace them, not the most stable operation...Brushless motors- This is a solution to many problems. They are quieter, run cooler, last much longer, and, as a result, provide a more powerful and stable flow of energy. This is especially important when working with hard materials.

I often come across questions: 'Should I switch to a brushless saw?' And my answer is always the same: 'Yes, it's worth it!' Yes, they are a little more expensive, but the long-term benefit is reliability and ease of maintenance. The savings on replacing brushes will pay off in full in the future.

Key Features You Should Pay Attention to

Before you start choosing a specific modelbrushless cordless saw, it is important to understand what to pay attention to. Here are a few key parameters:

Engine power

Power, measured in watts (W), is perhaps the most important indicator. The higher the power, the better the saw will cope with thick pieces of wood or other dense materials. The optimal value is considered to be from 600W to 1200W. For simple tasks, such as cutting thin boards, a power of 400-600W is sufficient. Pay attention to total power, not just peak power. Manufacturers often inflate peak power to attract attention, but it is the overall power that shows real performance.

Rotation speed (rpm)

The motor rotation speed affects the cutting speed. The higher the speed, the faster the saw will cut through the material. Typically, the rotation speed varies from 2500 rpm to 5000 rpm. For soft materials such as plywood, you can use a higher speed. For hardwoods, it is better to choose saws with a moderate speed.

Battery type and capacity

The battery is the heart of any cordless saw. There are several types of batteries, but the most popular are lithium-ion (Li-ion). They are lightweight, durable and have high energy density. Battery capacity is measured in ampere hours (Ah). The larger the capacity, the longer the saw will work without recharging. For professional use, I recommend batteries with a capacity of 4Ah and higher. When choosingbrushless cordless sawPay attention to battery compatibility. It is best to choose saws and batteries from the same manufacturer.

Overload and overheat protection system

This is a very important feature that protects the engine from damage in case of overload or overheating. The presence of this system is a good sign of the reliability of the saw. Some models are also equipped with short circuit and reverse polarity protection.

Ergonomics and ease of use

The saw should fit comfortably in the hand, have an adjustable length and comfortable handles. It is important that the weight of the saw is balanced and does not cause fatigue during prolonged use. Also pay attention to the presence of additional functions such as dust extraction and LED lighting.
