Loop Blades

Special wide diamond blades for concrete and asphalt

Standard diamond blades are generally 3.2mm thick. United Diamond Tools (UDT) make several types of extra wide looping blades for cutting concrete and asphalt. These are used for installation of loop detectors at traffic lights and car parks or for creation of expansion joints in concrete and asphalt surfaces.

These blades are available in standard 300mm (12") or 350mm (14") diameter and 4.6mm, 6mm and 10mm width.
We supply separate blades for concrete and asphalt. A concrete blade will cut asphalt, but it will wear faster. 
An asphalt blade may "glaze up" if cutting lots of concrete, but can be opened up by cutting some asphalt.

Note well!  These wider blades may mean your floor saw needs an increase in power. This may mean using a bigger horsepower saw. Alternatively, cut slower than normal, or step cut (cut in several passes rather than one deep pass).

All blades have 1"/25.4mm centre unless otherwise stated.
