Research and prototype shops
Short-run research machining burns premium tooling. Even modest shops accumulate valuable inserts and solid carbide — keep it separated and send photos when the container fills.
Prototype shops, research machine shops and tool rooms across the Madison area can send Ironcrest photos of carbide inserts, end mills, drills and tooling for evaluation.

Prototype shops, research and university-adjacent machine shops, and tool rooms across the Madison area.
Send clear photos, manufacturer or nameplate information when available, approximate quantity, city/state, condition and desired removal timing.
Madison is not a traditional heavy-manufacturing city, but its research economy runs real machine shops: university shops, biotech and medical-device prototype houses, engineering firms with in-house tool rooms, and the suppliers around them. Prototype and research machining is tooling-intensive — short runs, difficult materials, constant tool changes — and the carbide it generates is often premium-grade material.
Ironcrest buys from Madison-area shops and individuals. Because many sellers here are smaller operations, the process is simple: photograph the material, estimate the weight, and send it with your location. We review everything from a small accumulation of inserts to a full lab-shop cleanout and give a straight answer on value and logistics.

Shops supporting research institutions generate steady small lots of worn tooling. Accumulated over semesters of work, it adds up to a worthwhile lot.
Medical and biotech machining demands precision tooling with frequent changes. Clean carbide streams from these shops are exactly what we want to evaluate.

Yes, for qualifying lots. Send photos, an estimated weight and your location in the Madison area. We will review the material and discuss pickup, route service or mail-in depending on quantity.
Quite possibly — prototype work uses premium tooling, so small lots can carry strong value. Accumulate worn inserts and solid carbide in a dedicated container and send photos when it fills. We will tell you honestly whether pickup or mail-in fits.
We evaluate used carbide inserts, end mills, drills, burrs, tooling, wear parts and clean carbide scrap. We also review unused or new-old-stock tooling that may have resale value. Keep carbide separated from high-speed steel and other metals when possible.
Manufacturer markings, part numbers, density and the tool’s original use can help identify it. Do not rely on color alone. Send close photos of markings and the full tool, and note whether the material came from a CNC or machine-shop operation.
Mail-in review may be available for smaller, properly packaged lots. Contact us before shipping. Send photos and estimated weight first, then wait for packing, labeling and destination instructions. Do not ship a lot without confirmation.
Send photos, estimated weight, tool type, markings, and location for today’s price. Email sjohns@ironcrestindustrialsurplus.com or call 312-880-8174.
Industrial equipment can be worth more intact than as scrap. Clear photos and nameplates help determine whether resale, component recovery or commodity recovery is the best path.
