How to Choose the Best Impact Wrench
Pistol Style Impact Wrenches
The go-to tool for many professionals, the pistol grip impact wrench boasts an L-shaped design and compact dimensions that make it incredibly easy to maneuver. Its ergonomic shape allows for precision handling, making it perfect for tackling those hard-to-reach areas with confidence.
Electric-Corded, Cordless-battery-powered, and Pneumatic Impact Wrenches
Impact wrenches are available in various power sources: cord-electric, cordless-battery-powered, and pneumatic powered models. The choice of power source depends on the specific application and user preference.
Cordless impact wrenches offer the freedom of untethered movement, making them ideal for working in restricted spaces like underneath a car. They are typically powered by an 18- or 20-volt lithium-ion battery, such as the DEWALT DCF899P1 Impact Wrench.
One drawback of using a battery-powered impact wrench is that it can be heavier and bulkier than other models, and the battery needs to be fully charged for consistent power flow. However, this type of impact wrench is well-suited for tasks that require precision and maneuverability.
Electric-corded impact wrenches, such as the Porter-Cable PCE211, provide unlimited power for heavy-duty jobs.
They require a 120-volt outlet and a minimum of 6-foot power cord for effective use in a workshop setting.
Pneumatic impact wrenches are powered by compressed air and offer exceptional power for challenging tasks. This type of impact wrench may feature a double-hammer mechanism, making it highly effective at loosening stubborn lug nuts and bolts.
A pneumatic impact wrench, such as the AIRCAT 1150 or the ultra-compact Astro Nano, indicates its compatibility with an air compressor through PSI (pounds per square inch) and volume (cubic feet per minute). As such, it is essential to ensure that the impact wrench is compatible with your air compressor.
Pneumatic impact wrenches can be quite noisy, but a pair of industrial earplugs can eliminate much of the noise and keep your ears safe.
Impact Wrench Drive Size
The majority of impact wrenches come equipped with either a 1/2-inch or 3/8-inch drive size, catering to various mechanical and repair needs. For professional and home-related tasks that require more torque, the standard 1/2-inch friction ring is an excellent choice.
On the other hand, smaller and less-demanding applications might benefit from the more compact and lightweight 3/8-inch drive, as seen in products like the Astro 1828 Pneumatic Impact Wrench, which excels in these specific scenarios.
Torque
When it comes to measuring the might of an impact wrench, torque is a crucial factor. It’s typically expressed in foot-pounds (ft-lbs), with values ranging from a respectable 240 ft-lbs all the way up to an impressive 1400 ft-lbs of force that can effortlessly loosen or tighten bolts and nuts. As you’d expect, higher torque levels translate to faster results when working on stubborn fasteners.
Additionally, some impact wrenches may also display both their nut-busting and fastening torque speeds, providing users with a clearer understanding of the tool’s capabilities.
Rotations Per Minute (RPM)
When it comes to selecting the right impact wrench for your needs, understanding the concept of rotations-per-minute (RPM) is crucial. Typically, an average RPM range of 10,500 can be sufficient for smaller tasks and minor adjustments. However, if you’re dealing with more substantial vehicle repairs or stubborn bolts that refuse to budge, a higher RPM of 2,200 or even an ultra-fast 9,000 RPM may be necessary.
Fortunately, most impact wrenches come equipped with a variable speed RPM selector switch, allowing for precise control over the tool’s pace and ensuring you can tackle any job with confidence.
BPM
In the world of mechanical endeavors, two metrics are often cited: Blows-Per-Minute (BPM) or Impact-Per-Minute (IPM). These statistics gauge the frequency at which a hammer strikes an anvil within a minute. A higher BPM translates to a more potent impact wrench capable of effortlessly dislodging recalcitrant bolts. For instance, mechanics and classic car restorers frequently encounter lug nuts that seem glued in place.
To facilitate their removal, a clever trick involves applying a minimal amount of automotive lubricant to the nut prior to engaging the impact wrench. Following a brief pause, the bolt or nut can be effortlessly removed with ease.
Ergonomic Design
While compact and lightweight, impact wrenches can still become cumbersome with prolonged use, particularly cordless models. For those seeking a more diminutive tool, options like the AIRCAT 1150 or Astro 1828 are worth considering. However, when working in confined spaces or for extended periods, an ergonomic grip is essential to ensure safe and efficient operation. A comfortable rubber overmold handle or non-slip grip can make all the difference in preventing fatigue and accidents.
Safety Features
When it comes to additional safety features, some impact wrenches may include advanced battery designs that incorporate overheating protective measures. For instance, the Milwaukee 2767-20 and Makita XWT08T are notable examples of products that prioritize user safety in this regard. Furthermore, an LED light integrated into the impact wrench can provide valuable illumination in dark or confined workspaces.
