Overview
At 0.61 pounds, the Astro 93812 is light for anything filed under impact tools, pointing to an impact accessory or a compact impact attachment rather than a full sized impact wrench.
Astro Pneumatic's catalog spans full pneumatic impact wrenches down to small attachments and sockets, and the near ten ounce weight here fits the lighter end of that range. The listing gives no torque, drive size, or power source, so confirm exactly what the 93812 is before buying if you need a specific fit.
- 0.61 pound weight
- Filed under Astro's Impacts line
Who it's for
Best suited to someone who already knows this specific Astro part fits their existing impact setup. Not a safe pick if you are shopping for a standalone impact wrench, since the weight does not support that.
Pros and cons
- Very light at 0.61 pounds
- No drive size or torque rating listed
- Weight suggests an accessory, not a full tool
Performance notes
The 0.61 pound weight rules out a heavy duty standalone wrench and lines up instead with a compact attachment built to work alongside an existing impact tool.
