FEATURES: Metric version of our popular DG bushings, designed for cast-in-place or potted installation. 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.

STANDARD SIZES: see Dimensions page for part numbers and standard ID drill sizes. The prices shown apply to standard bushings only, with any standard metric ID size within the stated range.
