You own a used horizontal boring mill and you want to know what it is worth before you sell it. The value of big iron is not guesswork. It comes down to a handful of drivers: the configuration, the table and spindle size, the travels, the control generation, the condition, and the brand. Read those right and the number you hear back from a buyer will make sense instead of feeling like a coin flip.
This guide walks each driver, explains why a well-kept boring mill holds value better than most CNC machines, and tells you how to turn that into a real number. Jason Puuri runs acquisition at MTE and has valued and bought boring mills and other big iron direct from shops and facilities, so this is the same read he uses to price one.
If you already want a real number from a buyer who handles the rigging on a multi-ton machine, MTE buys boring mills direct nationwide. Call 800-822-9524 or get a free quote. Ready to move it now? You can sell your boring mill direct, no listing and no rigger to find.
What Drives the Value of a Used Boring Mill
What a used boring mill is worth comes down to the configuration, the table and spindle size, the X, Y, Z, and W travels, the control generation, the condition, the included tooling, and the brand.
There is no single number for "a boring mill." Two machines that look alike can be worth very different amounts because the specs underneath them are different. Here is the driver list, each one tied to what it does to the value:
- Configuration (table-type or floor-type). This sets which pool of buyers your machine reaches, which is the biggest single lever on value.
- Table size and load capacity. A bigger table that takes heavier parts opens the machine up to more work and more buyers.
- Spindle (diameter, quill versus ram). Spindle size and type drive capability and rigidity, which is what a buyer is actually paying for.
- X, Y, Z, and W travels. More travel means the machine handles bigger parts, and bigger-part capacity reaches a wider buyer pool.
- Control generation. A manual machine, an older CNC, a current control, or a retrofit each price differently. The control era and brand matter.
- Condition. Way wear, spindle health, and overall maintenance history move the number more than age alone does.
- Included tooling. A rotary table, angle heads, a facing head, a tailstock, and fixtures add real value because the buyer does not have to source them.
- Brand. A well-supported, reputable name holds value better, covered in its own section below.
The completeness of that picture is why a real buyer asks for specs and photos before quoting. If you want the cross-machine read on the same idea, here is what drives resale value across machine types, which covers the factors that apply to any CNC machine, not just big iron.
Table-Type vs Floor-Type, and Why Size Sets the Market
A table-type boring mill mounts the work on a rotary table for smaller, more precise parts, while a floor-type machine works oversized castings staged on the floor, and the size class places your machine in a different demand pool and value band.
These are the two main families of horizontal boring mill, and which one you have changes the whole conversation. A table-type machine holds the work on a rotary table and is built for parts that fit on that table, so it serves precision boring and a broad base of general machine shops. A floor-type machine sends the spindle and column to a part that is too big to put on any table, so it serves oversized castings and weldments staged on the floor.
That size class is what sets the market. Large floor-type machines feed aerospace, heavy-equipment, and energy heavy fabrication, the kind of work where parts are measured in feet and tons. Machines that big are scarcer, the shops that need them cannot wait long for capacity, and that scarcity supports the value. As general secondary-market context, used boring mills run from roughly the low five figures for smaller or older table-type machines up into much higher numbers for large CNC floor-type machines. Treat that as a market range, not a quote, because your actual number depends on the drivers above.
Why Big Iron Holds Its Value
A used horizontal boring mill holds its value better than most CNC machines because new ones carry long lead times and a high price, end-demand from heavy fabrication, energy, mining, and heavy-equipment repair is steady, and the machines last for decades with proper maintenance.
This surprises sellers who assume an old machine is nearly worthless. Big iron is different from a commodity machine. A new horizontal boring mill carries a long lead time and a big price tag, so a shop that needs capacity now often looks to the used market first. The end-demand behind that is steady: heavy fabrication, energy, mining, and heavy-equipment repair all need this capability and keep needing it. And a well-built boring mill lasts for decades with proper maintenance, so a machine from an earlier era can still be a working asset rather than a relic.
Put those together and a well-kept used boring mill is a durable asset, not a fast-depreciating commodity. That is why it usually beats both the scrap-metal number and the seller's low expectation of what it is worth. So do not scrap big iron before you know, because the machine value almost always beats the scrap-metal weight. If you want the value curve, here is how CNC machines hold or lose value. The machine's decades-long service life is about the iron, not about any seller or buyer.
Brands Buyers Look For, and What They Hold
Buyers actively look for well-supported boring mill brands like Giddings & Lewis, Toshiba, TOS Varnsdorf, Lucas, Union, and PAMA, and a reputable brand with available parts and known accuracy holds value better.
Brand is a real driver, and some names move faster than others. Buyers actively look for Giddings & Lewis, Toshiba, TOS and TOS Varnsdorf, Lucas, Union, and PAMA, because those machines have known accuracy, available parts, and a track record the buyer can trust. A reputable, well-supported brand holds value better than an off-name machine of the same size.
But brand does not work alone. It interacts with size, control, and condition. A strong brand does not rescue a machine that is worn out, missing tooling, or running an obsolete control with no path to support. And a lesser-known brand in genuinely good shape, with the right tooling and a sound spindle and ways, can still command a fair number because the capability is there. Brand sets the starting expectation, and the specs and condition decide where the number lands. If you want the full valuation picture, here is what your machine is worth across brands and machine types.
How to Get a Real Number
To get a real number on a used boring mill, gather the make, model, serial, and year, the hours if known, the control type, the table and spindle specs, the travels, and the tooling list, then take photos of the data plate, the control, the table and spindle, and the ways.
You do not need to become an appraiser to get a fair, accurate number. You need the right details in front of a buyer. Gather these:
- Make, model, serial number, and year.
- Hours of operation if the control tracks them.
- Control type and generation, and whether it has been retrofit.
- Table size and load capacity, spindle diameter, and the X, Y, Z, and W travels.
- The tooling list: rotary table, angle or facing heads, tailstock, fixtures, and any accessories.
- Photos of the data plate, the control, the table and spindle, and the ways.
That packet is what any honest buyer values against. Most sellers do not need a formal appraisal just to sell, because a direct buyer prices the machine from those specs and photos. A formal appraisal exists for specific reasons, such as settling an estate, supporting a tax position, or dividing value among partners, and if your situation calls for that you can get it appraised. One more point worth saying once: where the machine physically sits does not cap a national buyer's offer, because the buyer comes to the machine. And the line worth repeating, do not scrap big iron before you know what it is worth, because the machine value almost always beats the metal weight.

The Fastest Path: Sell Your Boring Mill Direct to MTE
If you want a real number without managing a sale or arranging heavy rigging, MTE buys used boring mills directly nationwide, gives a fair market-based quote typically within 24 to 48 hours, handles the heavy rigging and freight, and pays at pickup.
Having walked the value honestly, here is the plain recommendation for an owner who wants a real number without running a sale. Machine Tool Exchange is the actual buyer. Not a broker, not a marketplace, not an auction, not a consignment shop. The rigging point lands hard on a boring mill, because the machine is multi-ton and usually bolted to the floor, so "list it and arrange your own rigging" is a real burden. MTE removes it. We buy any brand and condition, running or not, a single machine or a full shop, in all 50 states, with no commissions and no listing fees. Jason Puuri runs acquisition at MTE and writes the check directly, so you are dealing with the buyer, not a middleman passing you along.
Step 1: Tell Us What You Have
Give us the make, model, serial, and year, the hours if known, the control type, the table and spindle specs, the travels, and the tooling list. Photos of the data plate, the control, the table and spindle, and the ways speed the quote. Call 800-822-9524 or tell us what you have through the online form in a few minutes.
Step 2: Get a Market-Based Quote
MTE values the machine against current secondary-market data and the specs you send. The offer is transparent, with no lowball formulas and no obligation, and it typically comes back within 24 to 48 hours. That timeline is typical market context, not a guaranteed turnaround, and the number is a market-based offer, not a fixed formula.
Step 3: We Rig It, Haul It, and Pay at Pickup
Accept the quote and MTE arranges and pays for the heavy rigging and freight nationwide, works around your schedule, and pays at pickup. You do not find a rigger, book a crane, or coordinate a heavy haul yourself. One quote, one pickup, one payment.

Why Sellers Choose MTE
Here is the short version of why owners sell their boring mills to MTE directly:
- Direct buyer, not a listing service. MTE purchases your machine outright with our own money, takes title, and pays you. No consignment, no marketplace listing, no waiting on a third party to appear.
- No commissions, no listing fees. The quote you accept is the amount you receive, with no buyer premiums and no deductions at the end.
- We handle the heavy rigging and freight. On a multi-ton machine bolted to the floor, that matters. We arrange and pay for disconnection, rigging, and freight.
- Any brand, any condition, running or not. Giddings & Lewis, Toshiba, TOS, Lucas, Union, PAMA, or anything else, in production or sitting idle.
- Nationwide, all 50 states. Distance is our logistics problem to solve, not yours, so where your machine sits does not limit the offer.
- Single machine to a full shop. One quote and one pickup schedule, whether it is one boring mill or an entire floor.
Frequently Asked Questions
How much is a used horizontal boring mill worth?
It depends on the configuration (table-type or floor-type), the table and spindle size, the X, Y, Z, and W travels, the control generation, the overall condition, the tooling that comes with it, and the brand. Used boring mills span a wide range, from the low five figures for smaller or older table-type machines up into much higher numbers for large CNC floor-type machines, which is general market context and not a quote. A direct buyer like MTE can give you a fair, market-based number from your specs and photos, typically within 24 to 48 hours. Call 800-822-9524.
What drives the resale value of a boring mill?
The biggest drivers are the configuration and size (table-type versus floor-type, table load capacity, spindle size, and travels), the control generation (a manual machine, an older CNC, or a retrofit), the condition including way and spindle wear, the included tooling such as a rotary table, angle heads, and a tailstock, and the brand. A bigger machine that handles larger parts reaches a broader pool of buyers, and a reputable, well-supported brand in good condition holds value better.
Do boring mills hold their value?
Big iron holds value better than most CNC machines. New horizontal boring mills carry long lead times and a high price, demand from heavy fabrication, energy, mining, and heavy-equipment repair is steady, and a well-maintained boring mill lasts for decades. That combination means a used boring mill in good shape is a durable asset, not a fast-depreciating commodity, and it almost always beats its scrap-metal weight.
Should I scrap an old boring mill?
Almost never, not until you know what it is worth. A scrap dealer pays for metal weight, while a buyer who wants the machine as a working tool prices it on its capability, and those two numbers are far apart. Boring mills are durable and stay in demand, so even an older or non-running machine is usually worth many times its scrap value. Find out the machine value first, because scrapping is irreversible.
Who buys used boring mills, and do I have to arrange the rigging?
Direct buyers like MTE purchase used boring mills outright nationwide and handle the heavy rigging and freight, which matters because a boring mill is a multi-ton machine usually bolted to the floor. You do not arrange a rigger or a truck yourself. MTE buys any brand and condition, running or not, single machine or a full shop, takes title, and pays at pickup, with no commissions or listing fees.
