Keystone Engineering is the leading innovator of tooling systems and drum designs for grinding equipment and has a long standing reputation for excellent quality and customer service. Skid steer attachment designed to smooth pavement roughness by shaving high spots and other irregularities in a cost effective manner. The Flatliner uses Flat Tooth Technology, a machined and precise holder system to insure a smooth and uniform surface, setting a new industry standard.
The Flatliner can deliver precise depth control, cutting widths of 2" to 49" and with 100% surface coverage. Interchangeable PCD Diamond Tools for different grinding applications. Change the cutting width by simply adding or removing PCD Diamond Tools. 100 percent surface coverage with Keystone's flat tooth tool eliminates the need for multiple passes during pavement marking removal.
Minimize surface damage during the removal process.
