If you plan to buy a Makita grinder or other reliable manufacturer, it is important to determine the number of pens. A one-handed tool usually has a power of not more than 1,500 watts, often it is used as a cutting or grinding. It is important to consider that it is better not to install circles with a diameter of more than 150 mm on such grinders.
The power of two-handed grinders is usually 2,000 or more watts, they can be installed circles with a diameter of 180 mm. Thanks to these discs, it is easy to cut concrete, brick and hardened steel..
Choose the speed of rotation of the disks
The rotational speed of the disk reports the number of revolutions that the grinder spindle performs in one minute. In a modern power tool, this indicator is usually in the range of 2,700–11,000 rpm. For small circles, the speed is higher and it may well reach the maximum mark.
In a tool with large circles, the spindle speed is not so high, often it does not exceed 6,500 rpm. If it is an order of magnitude higher, the result of such a violation may be the destruction of the disk.
Premium segment angle grinders have speed controllers. Thanks to them, the owner can independently set this indicator and achieve the perfect cut or grinding.
To choose the right grinder, you need to spend some time and effort. The reward for this will be the purchase of a tool that is useful on the farm and does not require overpayments.
