BLUEROCK Model Z1VB Universal Vacuum Base for Concrete Core Drill Stand
Platform dimensions: 17″ x 15″ x 2.5″ Overall height: 5.5″ Mounting stud height: 3″
Center mounting bolt to the edge of the base: 6.25″ (believe this measurement to permit for large diameter coring bit clearance and your core drill stands anchoring point when it comes to the edge of your coring bit)
BLUEROCK Tools Z1VB is a universal vacuum base for concrete drill stands. Designed to mount your existing concrete core drill stand and be pressurized with a vacuum pump. We now have a separate listing to buy this base with a vacuum pump as a package deal.
Vacuum bases don’t seem to be designed to work in each environment or application. Very rough surfaces, cracks or very uneven surfaces will reduce suction. Optimal adhesion is achieved on smooth and flat concrete with a strong vacuum pump.
