VERIFY YOUR DRAWTUBE THREAD SIZE
This collet chuck will only fit on Haas ST-25 and DS-30Y lathes that feature an M85 thread. Please refer to the layout drawing of your machine to verify the drawtube thread and ensure an accurate fit.
NOTE: Spindle reduction sleeve/liner length may need to be modified.
Part Transfer Minimum Distance
NOTE: Ensure that your part transfer distance is suitable for your application. The part transfer minimum distance will vary depending on your machine and collet chucks.
For dual-spindle applications, we recommend referring to your machine's dedicated machine layout drawing (MLD) to determine the face-to-face distance between spindles.
For legacy machines, this distance may be manually measured.
After subtracting the overall length of your chucks from the spindle face-to-face distance, determine if the resulting part transfer minimum distance is too large for your intended workpiece. Alternative solutions may be required for proper part transfers.
