- Harbor Freight Air File 1704
- Brand: Harbor Freight | Category: Files and Rasps

I recently purchased the Harbor Freight Air File. This thing works like a charm. A little heavy but works great, the online specs state 8.5 cfm, however the manual states 4.0 cfm. Harbor Freight is forever getting the specs wrong on there stuff. “Always check the manual, never rely on the online specs”. The files included are surprisingly of good quality. The tool requires the files to have a tang of ¼ inch. This little gem is very quiet, and no vibration. And for 17.99 again how could I go wrong.
From Harbor Freight Specs
There’s no faster, more efficient way to handle filing and small grinding jobs.

Stroke: 23/64”

I don’t suppose one could use some kind of collet to allow one to use smaller files ? Thanks for the review .

Funny you should mention that. I machined one over the weekend to accept 1/8 file tangs.
