Road Drilling Core Machine

lite's Pavement core drill machine is used to drill engineering sampling and hole of fixed  protective rail for the highway and municipal foundation.It uses gasoline engine as the power for easy start up, reliable running and simple operation, it is also equipped with synthetic diamond thin wall bit. The machine's drill bit is compatible with imported ones, the machine can achieve automatic core drilling.The max drilling depth is 700mm(with additional rod can reach max 500mm) .For high-grade highway concrete, asphalt, limestone based on compressive strength, bending experiment research core is very ideal. Features 1). Use imported gasoline engine, drive conveniently, run reliably, operate simply2). No need electric power3). equipped with man-made PCD thin drilling bit4). Boring and sampling size accurately5). The surface is smotth after boring, don't damage the drill materials Model LT-20 Core Drilling Diameter 20mm-350mm Max Core Drilling Depth 700mm (with additional rod can reach max 5000mm) Drive:  Honda GX390, air-cooled, 4 stroke, single cylinder, vertical axis Motor Power 13hp Main Shaft Speed 1400/min Boring Direction vertical down Feeding Mode Manual Machine Net Weight 178k
