Product Description

The DORIAN TOOL 73310104084 is a milling machine drawbar designed to secure tool holders in the spindle of a vertical milling machine. It measures 24-1/2 inches overall length with a 6-1/2 inch hex length and a 1-3/4 inch thread length, threaded at 7/16-20. The bar length is 18 inches. This drawbar is a direct replacement component installed by machinists and machine tool technicians performing spindle tooling maintenance or setup changes on compatible milling equipment.

This drawbar is suited for use on vertical knee mills and similar milling machines that require a 7/16-20 threaded drawbar for retaining R8 or compatible tool holders in the spindle. It is listed as compatible with Aliant and Sharp milling machines, making it a practical replacement for worn or damaged OEM drawbars in production and job shop environments. Machinists and maintenance technicians working on these machine platforms will find this a direct-fit option for restoring proper spindle tooling retention.

Installation Notes

Installation should be performed by a qualified machinist or machine tool technician. Always power down and lock out the machine before accessing the spindle or removing tooling.
