Ampco CR-10-ST Pneumatic Chisel

The Ampco CR-10-ST is a non-sparking pneumatic chisel built for use with air hammers in environments where ignition risk must be avoided. Its aluminum bronze construction meets safety requirements for hazardous locations. The tool accepts a standard .401 in round shank for quick changes.

Suited for maintenance crews in refineries.

Workers removing scale, cleaning welds, or cutting off bolt heads in explosive atmospheres will find the non-sparking material essential. Teams needing a powered scaler for general workshop metalwork without spark hazards should consider alternatives not rated for classified zones.

Shank size .401 in round

This dimension determines compatibility with the operator's air hammer; the chisel will not fit tools that take a different shank diameter or shape. Verify the hammer specification before ordering.

Questions about this item

How do I fit the .401 in shank into my air hammer, and what step is often missed?

Slide the round shank into the hammer's chuck until the collar seats, then tighten the retainer fully; the step most people skip is verifying the collar is flush before locking it.

What part of this chisel will wear out first and need replacement?

The flat chisel tip made of aluminum bronze dulls with use on bolt heads, welds, scale and paint; when the 1 1/4 in edge no longer cuts cleanly, replace the chisel.

At what point does sustained use hit a hard limit?

Continuous operation is limited by the air hammer's duty cycle and the 10 cfm supply; when airflow drops below what the tool requires, cutting power falls off.
