BME offers an attachment for the Davenport screw machine that can thread mill and polygon from the fourth-position cross slide. The attachment can cut threads with very little tool pressure, enabling it to be used on very thin parts, the company says. It also is suited for cutting threads on green dot brass, no-lead brass and materials that do not easily roll. Changing the gears in the thread milling attachment also enables it to cut hexagon, square, single or double flats from the cross slide.
The company also offers thread mill and polygon cutters in high-speed and carbide models.
