Which kinds of power tools are driven by compressed air?

Pneumatic tools, or power tools driven by compressed air, are valued for being lightweight, portable, and free from electrical shock or spark hazards. These tools generally fall into two categories based on their driving mechanism: rotary-vane motors or reciprocating pistons.12

Common types of pneumatic tools include:

• Portable Tools: These include grinders, buffers, sanders, drills, reamers, tappers, stud setters, screwdrivers, nutsetters, shears, wrenches, and impact tools.12
• Percussion and Impact Tools: This group features chipping hammers, riveting hammers, and various impact tools.12
• Rock Drills: Used for mining and excavation, these include hammer drills, drifter drills, and stoper drills.1
• Specialty Equipment: This category encompasses pavement breakers, concrete vibrators, countersinking tools, spikedrivers, paint mixers, air hoists, and spray guns for painting.31

These devices are highly reliable, often featuring simple designs with few moving parts, which helps keep maintenance costs low.3
