SPEEDAIRE 21AC10 air hammer

The SPEEDAIRE 21AC10 is a medium-duty air hammer designed for automotive and industrial tasks. It operates at 90 psi with an air consumption of 8 cfm and delivers 2,000 blows per minute. The tool features a round 0.401 in shank and a quick-change retainer for rapid accessory swaps. A 1/4 in female NPT air inlet connects to a minimum 3/8 in hose.

Mechanics needing a medium-duty impact tool

This hammer suits technicians performing panel cutting, rivet removal or general front-end work where a round shank and quick-change retainer are required. Users who need a different shank diameter or a non-round collar shape should look elsewhere. The side exhaust directs airflow away from the work surface.

0.401 in round shank with quick-change retainer

The 0.401 in round shank and quick-change retainer determine which chisels and accessories fit this tool. Verify that your existing bits match this shank size and collar shape before purchase. Compatibility with other shank dimensions or retainer types is not supported.

Questions about this item

How often will the quick-change retainer need replacing on the SPEEDAIRE 21AC10?

The quick-change retainer is a wear part; replace it when the chisel shank starts to wobble or the collar no longer locks securely.

What stops the tool first during continuous chiselling — air supply or heat?

At 8 cfm and 90 psi the compressor usually limits run time before the hammer body gets too hot to hold.

How loud and hot does the SPEEDAIRE 21AC10 get when run all day?

Side exhaust directs noise and heat away from the operator; expect typical air-hammer sound levels and a warm but manageable housing.
