The SR series internal Roll-A-Finish tools from Cogsdill are said to produce accurately-sized holes with fine surface finishes and work-hardened surfaces. The tools are offered in four standard work lengths, including 2″, 4″ and 8″ styles. They are available for through-hole or blind-hole applications and are stocked for hole sizes ranging from 0.187″ to 4″.
Standard tools are available for burnishing internal and external surfaces. Custom tool designs are offered for tapers, flat surfaces, contours and virtually any part configuration.
