Value Collection 209-9017 Milling Machine Drawbar 7/16-20

Product Description

The VALUE COLLECTION 209-9017 is a milling machine drawbar designed to secure tool holders and collets in the spindle of vertical milling machines. With an overall length of 24-3/16 inches (24.1875 inches) and a 7/16-20 thread size, this drawbar provides the clamping force needed to hold cutting tools firmly during milling operations. The bar length measures 17-1/2 inches. It weighs 4 pounds. Machinists and machine tool technicians install this part as a direct replacement or spare for machines that use the 7/16-20 drawbar standard.

This drawbar is sized and threaded to fit Bridgeport and Variable Speed Vertical Milling Machines. It is well suited to job shops, toolrooms, and production environments running vertical knee mills. Replacement is a routine maintenance task when existing drawbars show thread wear, bending, or failure to hold tension. The 209-9017 ships as a single unit and is stocked for individual replacement needs.

Installation Notes

Installation should be performed by a qualified machinist or machine tool technician. Power down and lockout the milling machine before removing or installing the drawbar. Thread engagement should be checked after installation to confirm the drawbar seats fully and holds tool holders without play. Follow the machine manufacturer guidelines for proper drawbar torque and maintenance intervals.
