What is the operating pressure range for the Air Chisel?

• A. 50 - 100 psi
• B. 90 - 250 psi
• C. 120 - 180 psi
• D. 150 - 300 psi

Answer: (B)

Air chisels need a certain window of pressure to work effectively: too little pressure and the tool can’t deliver a proper hammer blow, too much pressure can stress seals and valves and create unsafe conditions. The broad range of about 90–250 psi fits typical shop air setups—regulators often sit around 100–120 psi, but you can push toward the upper end for tougher work while staying within what many chisels are designed to handle. The lower options would not provide enough force for effective chiseling, and the higher option would push beyond common tool limits. So the operating pressure range is 90–250 psi.
