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.
How does pricing work on Aucto?
Depending on the listing, you can Buy Now at a set price or Make an Offer. Some lots sell in timed auctions. Pricing is transparent, with no hidden fees.
Is financing available?
Yes. Many listings offer monthly payment options so you can spread the cost of a machine. Look for the monthly payment estimate on the listing or contact our team to discuss available financing options.
How does shipping work?
Many Buy Now listings qualify for free shipping. Otherwise, Aucto works with freight partners across North America to help arrange delivery, with estimates available on request.
Can I inspect equipment before I buy?
Most listings include detailed photos, videos, specifications and inspection notes. Many sellers also allow scheduled in-person or virtual inspections through the platform.
