Carbide Thread Mills – 15 Series for Every Material and Thread Type

Why Choose Amony Carbide Thread Mills?

Carbide thread mills have become the preferred threading solution for modern CNC machining. Unlike traditional taps, one single thread mill can produce hundreds of different thread sizes and pitches, left or right hand, blind or through holes — with zero risk of tap breakage.

Amony offers a complete range of **15 dedicated series**, covering every material from soft aluminum to titanium and superalloys, and every major thread standard (Metric, UN, NPT, BSP, MJ, PG, etc.). Whether you need high-volume production, deep cavities, hard materials up to 68 HRC, or just want to reduce tool inventory, we have the right geometry and coating for you.

5 Major Advantages Over Traditional Taps

• No tap breakage – especially valuable in blind holes and expensive parts

• One tool = hundreds of threads – dramatically reduce tool inventory and changeover time

• Adjustable thread size – simply change program offset to compensate for tool wear

• Excellent for difficult materials – titanium, Inconel, hardened steel up to 68 HRC

• Superior chip control & surface finish – especially with our MF 3-in-1 and 7 Teeth series

Material-Specific Series

GT Series – general steel & cast iron
HT Series – hardened steel up to 68 HRC
ST Series – titanium, Inconel, superalloys
AL Series – aluminum, brass, copper (high helix + polished flutes)

Thread-Type Specific Series

UN Series – UNC/UNF American unified threads
NPT / NPTF Series – American tapered pipe threads
BSP / BSPT Series – British 55° pipe threads
MJ Series – aerospace reinforced threads with controlled root radius
PG Series – German 80° panzergewinde conduit threads

Special High-Efficiency Series

MF Series (3-in-1) – drill + thread + chamfer in one operation. In real tests on aluminum parts, one hole is completed in ~5 seconds.
   A60 / G55 Single Tooth Series – universal single-tooth tools that can cut almost any 60° or 55° thread size and pitch with one cutter.
   7 Teeth Series – combines advantages of 3-tooth and full-tooth, deeper flutes, lower cutting force, significantly reduced risk of breakage in small-diameter deep holes.

All Amony thread mills are made from ultra-fine grain carbide (0.2–0.4 μm), precision ground on 5-axis machines, with advanced coatings (AlTiN, TiSiN, DLC) and polished flutes. Available in single-tooth, 3-tooth, full-tooth, and long-reach versions.

Real customer results: an aerospace supplier reduced Ti-6Al-4V threading tool cost by 68% after switching to our ST Series; a mold maker cut inventory from 87 different taps to only 9 thread mills; a medical parts manufacturer achieved mirror-finish M6 threads in 316L stainless with zero scrap.
