Factors to Consider while Buying a Corded Electric Impact Wrench

With so many models available, selecting the right one is a complex task. There are several things to consider while buying an impact wrench. The most important one is the purpose for which you need the tool. Other features include torque, size, weight, RPM, and IPM. Some other characteristics are also worth consideration.

Motor Capacity

The power of a motor is directly related to its Amps. A motor with a higher number of amps provides more power. You can complete your work efficiently with an impact wrench having a motor of;

  • Regular Use: 7.5 to 8.5 Amps
  • Commercial Grade: 8.5 to 10 Amps

Corded electric impact wrench draws power from the direct electric source—thus, for work without any interruption, commercial grades are integrated with high Amps.

Torque

Torque is a twisting force that is generated by rotation, a significant element of impact wrenches to consider—without diving in too much technicalities; it is the indication of sheer power and performance. The Torque ranges are;

  • Entry Level: up to 600 ft lbs.
  • Commercial Grade: up to 1800 ft lbs.

The torque is genuinely for the power—likewise, the speed is not usually dependent on the torque of the impact wrench. Racers use impact wrench with mostly average torque ratio but highest RPM for fast changeovers.

Speed

The speed of motors is measured in RPM (rounds—revolutions per minute). The no-load speed of an electric impact wrench is likewise measured by Rpm.

The standards RPM of the electric impact wrench is;

  • Average Duty: 3000 to 5000 RPM
  • Heavy Duty: 5000 to 1100 RPM

To remember: The power of the impact wrench does not depend on the RPM, but we assess the power of a motor by its RPM. A powerful motor will have higher rpm and will produce more power when combined with suitable torque and IPM.

Impacts per Minute

Impact per minute shows the count of times the hammer strikes the anvil in a minute to move the socket in a forward or backward direction. An electric impact wrench with a higher number of RPMs usually has more IPMs. The range that you might consider is;

  • Entry Level: 2800 IPM
  • Commercial Grade: up to 3400 IPM

More the number of impacts will efficiently apply the force on the nut and save time by completing the work quickly.

Size of the Anvil

The anvil size must be according to your niche of work, different bolts/nuts need a specific size of tool to operate conveniently—for that, inspect your requirements (nut sizes) and select the electric impact wrench with proper size. The general range of sizes are;

  • 3/8 inch
  • 3/4 inch
  • 1/2 inch

½ inch is common in use for most of the operations. On the other hand, 3/4 inch is used for heavy-duty work. If you choose an inappropriate size, you will face trouble and might end up with failure.

Types of the Anvil

Two types of anvils are fitted in electric impact wrenches—detent pin anvil, hog ring anvil.

Detent Pin Anvil

A detent pin anvil uses a spring-loaded bearing to keep the socket in place. To change the socket with a detent pin anvil, you must compress the spring to release the socket. A detent pin anvil holds the socket more firmly as compared to a hog ring anvil.

Hog Ring Anvil

The hog ring anvil retains the socket with a steel ring in a groove on the square drive. Mostly present on the air impact wrenches. They are ornerier to fit the sockets, but likewise gets retains them better.

Weight

While holding the electric impact wrench, to avoid fatigue and strains on your body—go for the light weighted models. The weight range to consider is;

  • 4 to 9 pounds

The long hour working tenure needs weight that you can handle and as for the corded models, they are flurry because of no battery is present in them

Grip

Better the grip, more will be the accuracy, and less will be the strain of hands. Most of the models are integrated with;

  • Plastic Grip: light weighted—economical and usually comes in stock models of electric impact wrench.
  • Rubber Grip: good in hot weathers (stays firm while sweats), slightly weighted than the ordinary plastic ones.

Torque Adjustment

As it is said “with great power comes great responsibility”—the electric impact wrench while loosening or tightening nuts, can eventually break them. The adjustability of torque (power) will achieve you greater accuracy. The adjustability comes as;

  • Presets: Different adjustable points are given for a dedicated torque.
  • Knob: The power is increased as per user pushes the button deeper.

Maintenance

The usage of corded impact wrench makes the motor and the gear to worn out—heat has an impact on the moving parts. Maintaining them helps in exceeding their life expectancy and efficiency.

How to Maintain your Electric Impact Wrench?

The ways to maintain your electric impact wrench are;

  • Never use incorrect sockets or bits.
  • Never keep it in moist or damp place.
  • Clean dirt, if you have left it openly.
  • To prevent jamming, lubricate the parts when needed.
  • Clean after every use.
  • Never apply excessive torque.
  • Inspects the cord before using.
  • Check all the parts regularly.
  • Use a manufacturer-recommended lubricant.

Maintenance; Brushless Vs. Brushed Motor

The brushless motor needs less maintenance as compared to the traditional motor—they are much recommended; the low maintenance ensures long-term use.
