When it comes to using air tools for automotive work, many people focus on the size of the air compressor tank. While tank size does play a role, it’s crucial to understand that tank size is primarily about reserve capacity, not the continuous power of your air tools. The real key to effectively using Craftsman Air Tools For Working On Cars lies in the Cubic Feet per Minute (CFM) output of your compressor.
A smaller, 1-gallon air compressor, for instance, technically can power almost any air tool in the Craftsman range. However, its limited CFM and small tank mean it will only run the tool for a very short duration – perhaps just a few seconds – before needing to stop and repressurize. This is because the tool consumes air faster than the compressor can replenish it.

Consider a common scenario: using a high-demand tool like a Dual Action (DA) sander or a powerful 3/4″ impact wrench. With a 20-gallon “5hp” (peak horsepower) Craftsman compressor producing around 8 CFM, you can indeed operate these tools. However, for extended tasks like sanding or continuous impact wrench use, you’ll quickly find the compressor struggling to keep up. The pump will run constantly, and the air pressure will drop, diminishing the tool’s power. To maintain optimal performance, you’d need to pause frequently to allow the compressor to catch up.

For professional or more demanding applications in a shop environment, a larger compressor is a worthwhile investment. Upgrading to an 80-gallon true 5hp compressor, delivering over 20 CFM, drastically changes the experience. Such a system can power even the most air-hungry craftsman air tools for working on cars continuously, without noticeable pressure drops. The compressor cycles on and off intermittently, indicating ample air supply and consistent tool performance.

It’s also important to acknowledge the advancements in cordless power tools. The current generation of cordless tools has become incredibly capable, often rivaling or even exceeding the power of pneumatic counterparts. If portability and convenience are priorities, and you aren’t operating a full-time auto repair shop, cordless tools present a compelling alternative. Their versatility – being chargeable and usable with both 12V car batteries and 110V AC power – makes them exceptionally convenient for various locations and tasks. Ultimately, choosing between craftsman air tools and cordless options depends on your specific needs, workload, and working environment.
