What this tool adds
What this tool adds to your bench
The pivoting front jaw is the key reason to compare the 79A with a conventional face vise. The selected source gives a 10 degree pivot to help the jaw meet irregular work. Compare that movement with the actual shape you need to hold, rather than expecting one jaw arrangement to suit every part.
The selected jaw format is 4by10 inches, with a nominal13 inch maximum opening. The front jaw also moves vertically up to 9/16 inch to act as a full-width dog. Those are different dimensions and functions; the jaw-face size is not a stated throat-depth measurement.
Rapid release provides another way to reposition the jaw before tightening. The package lists two magnetic maple jaw inserts with the vise, and mounting hardware is sold separately. Check usable opening with the jaw facings you intend to use.
Choose this fixed bench installation for the pivot contact and raised-jaw function. Compare the Yost M9WW for a different quick-release format, or the portable Smart Vise if moving the work surface matters more. Follow the supplied mounting instructions and confirm the support and clearances for the selected vise.
Choose for your actual work
- Match pivot movement to the part’s actual shape.
- Plan mounting clearance and usable opening with the chosen facings.
Fit checks & limits
- No universal mounting fit or all-shape clamping guarantee is established.
- Jaw-face dimensions are not automatically throat-depth dimensions.
Questions before you choose
When is the pivot jaw useful?
Compare it when the two faces of the part do not meet ordinary parallel jaws well. The stated pivot is 10 degrees; the actual shape still determines the contact.
Can the front jaw serve as a bench dog?
The selected source describes vertical movement up to 9/16 inch for that full-width dog function. Plan it with the rest of the bench holding arrangement.
What needs to be provided for mounting?
The selected contents exclude mounting hardware. Check the supplied instructions, your bench construction and the clearances before choosing suitable fasteners.
