Description
There are some drilling situations where drilling on a large flat surface would prevent the Strong Arm 5’s / Strong Arm 5 MAX foot from grabbing the drilling material. This is solved with the vacuum cup set-up shown here (bar not included). Each cup is rated to hold up to 75 pounds and have a red-line indicator to let the operator know when vacuum seal has been achieved or when vacuum seal has been lost. The unistrut bar allows the portable drill press to anchor on any flat, smooth surface. Unistrut bars are available at most hardware stores and are not included. Unistrut bars coming in 10 foot minimum lengths would cost more to ship then it would be to purchase at your local hardware store.
- Use an Unistrut 13/16 in overall height, 1 5/8” in overall width
- Cut unistrut to length so you can have multiple drilling without moving setup
- Please click the Video tab to view the Pressure Video where you will see a set-up of vacuum cup holding 450 pounds of hold.
- The Wood vacuum cup will also hold onto a surface with a little curve to it.
- Vacuum cups can also work on semi-smooth surface
- Includes yellow protective covers
