About the 8-direction Benchtop Mill Column Upgrade

If you already own a 5000-series or 5400-series Sherline milling machine, or if you purchase one now with the thought of upgrading later, an upgrade package is available to convert your mill into an 8-direction mill when you feel its additional capabilities would be useful for your projects. A modified base and all the necessary attachment screws are included to adapt the new column to properly fit your 5000- or 5400-series mill. Also included is the column travel extension that allows the headstock to be brought down closer to the table.

The 8-direction Vertical Milling Column Upgrade includes an adapter base that offsets the column back an additional 2″ to provide the same Y-axis capacity as the 2000-series, 8-direction mill.

The 8-direction mill costs $225.00 more than the Model 5400 mill. Since upgrading the 5400 to the full capacity of the Model 2000 costs only $278.25, there is only a $53.25 difference in price if you are starting out. If budget is a consideration, this saves money upfront when you need it for accessories and allows you to convert later when your skill level can better take advantage of the additional movements of the 8-direction mill. If you have an older mill and would like to enjoy the increased capacity of the Model 2000 mill, this is an economical way of converting your machine compared to selling it and buying a new Model 2000 mill.

UPGRADE NOTE: If you are upgrading a current 5000/5400 series mill that has a brass tube leadscrew cover for the Y-axis, this column upgrade CANNOT BE USED without the removal of the brass tube. Another upgrade option is to purchase the Rigid Column Upgrade. These columns have rectangular bases and were designed specifically to upgrade the 5000/5400 series mills.

The improper use of machine tools and their accessories can result in serious injury. Before using this tool, thoroughly read the instructions and make sure you understand its proper and safe use.


Always wear safety glasses when operating machine tools.
