Used Tool Holders for Sale
Shop used CNC tool holders for sale on Aucto — CAT40, CAT50, CAT45 and HSK holders, collet chucks, facemill arbors and modular extensions from verified sellers across the US and Canada. Inventory is name-brand holders (Sandvik, Kaiser, Carboloy and similar), not no-name ER collets in a poly bag.
Match taper first (CAT40 vs CAT50 vs HSK63/HSK100), then projection, through-coolant, balance rating, and whether the holder is a collet chuck, end-mill holder, facemill arbor or modular (Varilock-style) extension. A CAT50 facemill arbor is a different buy from an HSK100 collet chuck; both appear here.
Match the taper to the spindle on your mill first — adapters are not a plan for production work.

Frequently Asked Questions
Everything you need to know about buying and selling on Aucto. Can’t find an answer?
What's the difference between CAT40 and CAT50 tool holders?
CAT40 is the common taper on 40-taper VMCs (Haas VF, Brother, many job-shop mills). CAT50 is the heavier taper on 50-taper machines and larger mills — more rigidity, larger facemills. Match the holder to the spindle. Aucto lists both.
Do you sell HSK tool holders?
Yes. HSK holders (including HSK100) appear in this category when they are in stock. Check the listing for the exact HSK size before you buy now or make an offer.
