Metric Keyway Bushings

duMONT Metric Keyway Bushings enable the operator to use individual metric keyway broaches in a variety of bore sizes. Both bushings and broaches are designated by a letter which signifies the width of the keyway broach and bushing opening. For proper fit, use bushings with the same letter designation as the broach being used — i.e. Metric A Bushings with Metric A Broaches. Metric B Bushings with Metric B Broaches, etc. F style broaches available for F style broaches on short delivery.
