The Dillon 1" Bench Wrench is compact enough to allow operation within the close confines of the tool heads on the "blue" Dillon progressive reloading machines. The open side of the spanner is sized to fit the 1" lock-nuts supplied with all current generation Dillon dies and the smaller closed ring fits the 7/16" powder measure adjustment bolt, and others.
The 1" Bench Wrench is included in Dillon's Toolkit for the RL 550B, the XL 650 and the Super 1050, or is available separately should the complete toolkit for your machine not be selected.
This item is highly recommended to aid setting up the Dillon machines.
