Things to consider when looking purchasing an impact wrench

Tightening or loosening bolts isn’t an easy task. Mechanical shop owners understand this fact well. As such, they invest in the right tools. They look for powerful, affordable and lightweight devices. If you are looking to buy an impact wrench consider the following factors;


Torque depends on the kind of motor. Higher torque enables faster working. Wrenches with higher torque are more capable than those with lower torque. With such a wrench, you can work faster and effectively. The pneumatic wrenches produce more torque as compared to the cordless counterparts. They get their power from compressed air. This way they work for more extended periods provided there is electricity. The corded types depend on their batteries, thus the lower torque.


You’d like to be in control while using your wrench. In that case, portability is essential. There are different sizes of wrenches in the market. A heavy wrench can be useful if you are working for short periods. If you work for longer, you get tired, and therefore you find it difficult to control and handle. Besides, while using the heavier versions, you might feel the impact of their rotating motions.

No load speed (Revolutions Per Minute – RPM)

No load speed indicates the rate at which an impact wrench rotates when not working. A high-speed caliber will work faster. The RPM depends on the torque. When torque is higher, the RPM and the IPM (impacts per minute) is higher too. You’ll choose your preferred impact wrench depending on the kind of job you’ll put them to. The more robust the job, the more torque you’ll need. The pneumatic wrench has a higher RPM.

Torque adjustments

A high performing impact wrench allows for changes on the torque. You can control the torque output to meet the demand of the job you are doing. Make proper adjustments to reduce the chances of accidents. Excessive power can destroy your accessories and studs. For instance, if you apply extreme power, bolts might snap causing accidents.

Wrench Drive size

The drives sizes include the 0.25-inch, 0.50-inch, 0.75-inch, 1.0-inch, 1.25 inch, and 3½” drives sizes. However, there exist larger forms of wrench drives sizes. The type of wrench size you buy depends on the usage. Each size has its specific design, hence a particular purpose. However, 0.50-inch works with most applications.

Type and size of the handle

Ergonomic handles will allow you to balance your tool well while working. Besides, such handles are very comfortable, reducing fatigue. The engineering technology of impact wrenches vary. So, find the type fits your hand. The handle material must be comfortable. This way you reduce strain and fatigue.


The cordless impact wrenches use batteries. You can swap the batteries, provided it is the same brand. The best battery technology so far is the Li-ion. You’ll need to charge them frequently because they lose charge faster.


The average warranty period of a wrench is two years. However, a few manufacturers offer longer periods. You must purchase an impact wrench from a manufacturer that provides a reasonable warrant. Such warranty cushions you against the manufacturer’s faulty artistry. So pick a reliable warranty option.
