    Diamond-Groove Bushings (DG)

    Diamond-Groove Bushings (DG)

    Drill-Jig Bushings

    Diamond-Groove Bushings are designed for cast-in-place or potted installation. The diamond-knurled OD provides excellent holding strength against both rotational and axial forces. Since the bushing's OD is not ground, the ID must be accurately located during casting or potting to ensure accuracy in the finished tool.

    To order a specific standard bushing, select the basic part number below and add the desired ID drill size (as a 4-place decimal inch) on the Price & Availability screen. See Technical Information tab for Standard Drill Sizes. Standard prices apply only to bushings with a standard inch, number, letter, or metric ID size within the stated range. Long bushings with ID sizes marked * are counterbored according to ANSI standards for proper drill-bearing length.

    Example standard bushings:
    DG-26-16-.1875 3/16" ID (.1875)
    DG-26-16-.1772 4.50mm ID (.1772)
