Used UNISIG Machines We Buy
Used UNISIG deep hole drilling machines are the whole of this page: 41 listings, one nameplate, one category. Machine Tool Exchange buys them outright from the companies that own them, no broker and no consignment. UNI is the largest group at eight, then B500 and USK50 at five each. Here is what we look at before we make an offer.

What Is in the UNISIG Book Right Now
Forty-one machines carry the UNISIG nameplate here, and that count is exact rather than rounded off a sample. UNISIG is the only brand on the page, so there is no sorting by nameplate to do. All 41 file under one category, CNC Deep Hole Drilling Machines, so there is no sub-split to check and no second listing view to open. That makes this a narrow page rather than a broad one, and it is worth saying plainly instead of dressing it up. Build years are thinner than the machine count suggests: only seven of the 41 listings record a year, and those seven run 1999 to 2021. That is why we ask a seller for the year off the plate rather than inferring it from the model. For scale, on our deep hole drilling machine page UNISIG is the largest of the six brands listed there, carrying 41 of the 61 machines on it.
UNISIG Model Groups, and Why the Full String Matters
Seven repeating groups cover 26 of the 41 rows. UNI leads at eight, B500 and USK50 sit at five apiece, and USK75, USK38, KSG and B600 each show up twice. The remaining 15 rows sit below that two-count cutoff. The useful part for a seller is not the roll-up, it is the string itself. Under a single prefix these machines are not interchangeable. USK50, USK50-1000, USK50 500, USK50 BTA-2000 and USK50-BTA2000 are five separate rows here, and a shop hunting one of them is not shopping for the other four. The same holds on the UNI side, where UNI-20-2-500 BTA, UNI-20-6-1000, UNI-6-4-2I, UNI-T25-2I-45, UNI-25HD-2-250 and UNI-50BTA all sit under one prefix and none of them substitutes for another. UNE6-750-CR shares its first two letters with UNI and is a different designation again. So give us the full string off the data plate, not the shorthand people use around the shop.
Gun Drill or BTA: Which UNISIG You Have
Both drilling methods sit under this one nameplate, and they are not the same sale. What separates gun drilling from BTA, and which one suits which job, is covered in full on our CNC deep hole drilling machines page rather than repeated here. What is UNISIG-specific, and genuinely useful when you are selling, is that on this nameplate the method is usually legible from the designation itself. Seven of the model strings in this book carry BTA right in the name: UNI-20-2-500 BTA, UNI-50BTA, USK50 BTA-2000, USK50-BTA2000, USK75-200BTA-CR, B500 BTA and BTA-2000. Not every builder is that plain about it on the plate. It matters before condition ever comes up, because BTA machines and gun drills serve different shops, so the designation changes who wants the machine. If your plate does not say either way, describe the bar and the coolant setup and we will place it correctly before anyone talks about a number.
Discontinued UNISIG Models Still Get an Offer
Much of what sits in this book is a configuration UNISIG no longer builds. For a seller that is not a mark against the machine. It is the reason a shop that wants one has to buy it used at all. Catalog availability is not what we look at. We look at whether the machine still holds tolerance, whether the control is serviceable and parts are still reachable, whether the boring bars, whip guides, bushings and tooling are coming with it, and whether it is still under power. Any condition works: running, sitting idle since the job that paid for it ended, or needing spindle work. The one-off designations here, M-1146, M1121-2, USC-M38 and USC75-1500 among them, get scoped the same way. Say the condition upfront rather than letting us find it at the dock. An offer built on an accurate description holds at pickup. One built on an optimistic description gets revised.
What Moves the Number on a Used UNISIG
Drilling capacity comes first, meaning max depth and max diameter. On UNISIG the designation usually carries numbers right in the string, which is why UNI-20-6-1000, USK50 500, USK75-200BTA-CR, USC75-1500, UNE6-750-CR and KSG-1000NC look like they are telling you something before anyone opens a spec sheet. We do not publish spec interpretations for these families and will not guess at one, so give us the real depth and diameter off the machine. After capacity: spindle count and spindle specs, control type, the coolant and chip evacuation system, whether it still holds tolerance, and what tooling travels with it. Jason Puuri weighs all of that against what shops are asking for right now, rather than running the machine through a formula. Photos help and are not required. Once we have the details, an offer typically comes back within 24 to 48 hours. Missing a number is fine, just tell us it is missing. Guessing at one is not.
Selling a UNISIG Direct, and What Else Goes on the Quote
MTE is a direct buyer. You sell to us, not through us, so there is no listing fee, no broker fee and no waiting on somebody else's buyer to turn up. Rigging, crating and freight are ours, at no cost to you, in all 50 states. Payment happens at pickup rather than on net-30 terms, which matters more than usual here, because deep hole drills are long, heavy and awkward to move. We buy past this nameplate too. We also purchase Eldorado, TBT, Nagel and SIG gun drills, Heller and Mollart Engineering BTA machines, multi-spindle gun drilling machines and combination gun drill and BTA systems. None of those are in the UNISIG book on this page. They are on our buy list, which is a different thing. And if the UNISIG is not the only machine leaving the floor, lathes, VMCs and HMCs go on the same quote and the same pickup schedule.
Common questions
Who buys used UNISIG machines?
Machine Tool Exchange buys them outright. We are a direct buyer, not a broker and not a listing service, so you sell to us rather than through us.
Do you buy UNISIG gun drills and BTA machines both?
Both. Seven designations in this book carry BTA in the name, including USK50 BTA-2000 and B500 BTA, and we buy gun drilling machines just as readily.
What details do you need to quote a UNISIG?
Brand, model, year, condition, max drilling depth and diameter, drilling method, spindle specs and control type. Give us the full string off the data plate, not the prefix.
Will you buy a UNISIG that is a discontinued model?
Yes. Discontinued means the factory stopped building that configuration, not that the machine has no buyer. Used is the only route left for a shop that wants one.
Will you buy a UNISIG that is idle or needs spindle work?
Yes. Any condition: running, sitting idle after a job ended, or needing spindle work. Tell us upfront and the offer holds at pickup.
Do I pay for rigging and freight on a UNISIG deep hole drill?
No. Rigging, crating and freight are at no cost to you, in all 50 states, and payment happens at pickup rather than on net-30 terms.
Do you buy deep hole drill brands other than UNISIG?
Yes. We also purchase Eldorado, TBT, Nagel and SIG gun drills and Heller and Mollart Engineering BTA machines, plus multi-spindle and combination gun drill and BTA systems.
Thinking about selling UNISIG Machines?
Much of this UNISIG book is configurations the factory no longer builds, which is why a shop that wants one has to buy it used. That works in your favor as the seller. Send the full designation off the plate, the depth and diameter it drills, and the control, and Jason Puuri puts a number on it himself. Rigging and freight are ours.
