The latest in a string of successful applications for Penhall Diamond Products V-Max wall saw blade involved a warehouse wall sawing contract at Houston, Texas. The job involved cutting a new 9 m wide, 6 m high opening for fork lift traffic. In the event, concrete cutting specialist, Houston Sawing and Drilling accomplished the whole job in one working day using 600 mm Penhall V-Max blades.

With their copper centre layer and unique multi slots, the laser welded blades employed 15 mm high, V-Max, second generation segments from Nimbus and according to the contractor cut substantially faster than other blades previously tried. At the same time there appeared to be no loss in blade life.

The 200 mm thick warehouse walls comprised heavily reinforced concrete with hard, chert and flint aggregate. Using a 20 hp hydraulic wall saw the contractor accomplished full depth of cut in three passes and achieved a cutting rate of 14 in/ft per minute in steel, even though the blade had to cut longitudinally through the 16 mm diameter rebars.
