What Tooling and Workholding Should Convey in a Sale
The spindle sells the machine, but the tooling and workholding decide whether you can run a part the day it lands.

On a used machine, the iron is only half the deal. Toolholders, collets, chucks, vises, fixtures, probes, and the control options that drive them are where value quietly lives or walks out the door. Spell out exactly what conveys in writing before money moves, because a stripped machine is a project, not a purchase.
Buyers price the spindle and forget the rest. Then the truck shows up, the machine is bare, and the first job is a shopping list instead of a part. The gap between a machine that runs and a machine that sits is almost always tooling and workholding, and almost always a conversation nobody had.
The Delta Arc way to look at this: value does not live in the casting alone. It lives in whether the asset can make money the week it arrives. Tooling and workholding are what close that gap, and they are the easiest thing in a deal to misunderstand, overpay for, or lose.
What actually conveys, and what quietly walks
Start with a plain distinction. Some items are effectively part of the machine. Others are consumables and personal kit that a seller expects to keep. Trouble starts when the two sides draw that line in different places.
Things buyers assume convey but frequently do not: toolholders and the pull studs that match them, collets and collet chucks, the power chuck and its soft and hard jaws, the tailstock and steady rests, vises, the rotary table or indexer, and any custom fixtures. On a mill, a wall of CAT or BT holders is real money and real lead time to replace. On a turning center or lathe, the chuck, jaws, collet setup, and bar feeder interface can equal a meaningful slice of what you paid for the machine.
Then there is the quiet layer most buyers never ask about: software and control options. A probing cycle is worthless without the probe, the stylus, and the option enabled on the control. High-speed machining, rigid tapping, extra memory, and tool-management features are often licensed. The hardware can be bolted on and the function still dead because the option was never purchased. Confirm the option, not just the part bolted to the spindle.
The consumables line
Perishable cutting tools, inserts, and half-used coolant are normally the seller's to keep, and that is fair. What is not fair is discovering that "tooling included" meant a box of dull drills while the collets and holders left with the old owner. Say the words. List the categories. Ambiguity in a used-equipment deal always resolves in favor of whoever is holding the wrench.
How to put it in writing before money moves
The fix is boring and it works: an itemized schedule attached to the invoice or purchase agreement. Not "tooling included." A list.
- Workholding: chuck make and size, number of sets of soft and hard jaws, vises by count and make, rotary or indexer, tailstock, steady and follow rests.
- Toolholding: holder type and taper, how many, pull studs included or not, collets and the collet series, any boring bars or live tooling for the turret.
- Metrology and automation: spindle and tool-setting probes, tool presetter, part catcher, bar feeder or loader, and whether the control option for each is enabled.
- Documentation: manuals, ladder diagrams, parameter and backup files, maintenance records, and remaining machine passwords.
That last line matters more than it reads. Parameter backups and the maintenance logbook are close to free for the seller and expensive for the buyer to reconstruct. They convey trust as much as data.
Photograph the machine as configured at the time of agreement. A dated photo of the tool carousel loaded and the vises on the table settles most disputes before they start. If an item is explicitly excluded, name it in the exclusion, so silence never gets read as inclusion.
How tooling reads the person across the table
Tooling also tells you who you are dealing with. A seller who hands you a clean itemized list, backups, and a loaded carousel is telling you the machine was run by people who cared. A seller who waves at a pallet and says "it is all there" is telling you something too.
On the buy side, the same logic reads the market. When a specific category tightens, well-tooled machines move first and bare ones linger, because a buyer under pressure to make a part cannot wait weeks for holders. On vertical machining centers especially, a complete tooling package can be the difference between a quick sale and a stale listing at the same spindle price.
So price the package, not the plate. Ask what conveys before you ask what it costs, because the answer to the first question changes the second. A bare machine is not cheaper. It is a machine plus a project you have not scoped yet.
