A unique machine specifically designed for laboratory use to precisely cut Asphalt, Concrete and Rock samples

Suitable for Asphalt and Concrete samples
High rigidity and stability
Slab and prism of any shape and dimensions can be sawn without additional accessories (see table for maximum dimensions)
Jig for round cores, from 100 to 150 mm dia, length up to 300 mm
Unique clamping mechanism for cylindrical specimens minimizes specimen damage. Use of a sacrificial PVC tube produces a superior finish and minimizes edge chipping of asphalt samples
Easy spacer system allows precise preparation of beams or cores without the need for measurement i.e. 50 x 63 mm or 70 x 70 mm or other sizes
Manual advance and retraction of saw blade to home position
Motor mounted on twin chrome-plated steel rails with sealed bearings
