Asphalt cutters can come in a variety of sizes and capabilities, from hand-held units to large machines designed for large road construction projects. Choose the milling surface according to the size of the project and the depth of the asphalt. Smaller milling surfaces are designed for narrow areas and detail work, while larger ones are for large surfaces and deeper milling. Specify the requirements of your project and contact the rental company to discuss which milling surface would be most suitable.
