Which impact wrench is better to buy?
One of the main characteristics of a tool should be considered its power - it directly affects the working life and scope of application of the impact wrench. Professional models have a power of more than 1000 W and are designed for intensive use.
Irregular use of the impact wrench at home or in a small workshop will not require power exceeding 500 W.
Another important parameter of a wrench is torque. Incorrect selection of this value can lead to thread stripping or cartridge breakage during the process of tightening the nut. When laying a railway or carrying out serious installation work at height, it is better to use a model with a torque of more than 600 Nm. For domestic use, 150 Nm will be sufficient.
You should pay attention to the spindle speed. The required value also depends on the nature of the impact wrench:
- A model with a speed of about 100 can successfully handle small household tasks.
- For use in professional conditions, we recommend purchasing a tool with a speed of at least 3000 rpm.
Modern impact wrenches are divided into impact and static ones. The features of the former are low weight and high rotation speed, which makes them widespread among installers and builders. Static devices provide constant torque, but are characterized by large dimensions.
Manufacturers equip their models with various additions for comfortable and safe operation. These include electronic speed control and an emergency brake. These functions reduce the rotation speed, help to quickly shut down the motor when thread defects are detected, which extends the life of the impact wrench. Operation will also be facilitated by lighting, an additional handle, and brackets for placing the tool on the belt.
