The Carmex External Threading Insert Kit is a ready-to-use toolset for creating external threads in stainless steels and exotic materials. Featuring a PVD TiAlN coated sub-micrograin carbide, these inserts maintain sharp, consistent cutting edges for reliable performance at medium to high speeds (P20–P40, K20–K30). The kit includes two inserts of each size across five common external thread pitches: 16ER1.0ISO BMA, 16ER1.25ISO BMA, 16ER1.5ISO BMA, 16ER1.75ISO BMA, and 16ER2.0ISO BMA.

• Coated sub-micrograin carbide for long life at speed: PVD TiAlN coating enhances wear resistance and edge stability, helping you achieve clean, accurate threads on tough materials at higher cutting speeds.
• Five-size kit with two inserts each: Immediate coverage of common external thread pitches with two inserts per size, reducing tool changes and keeping production moving smoothly.
• Reliable external threading in demanding materials: Built on BMA-grade carbide for durability and consistent results, delivering dependable performance across stainless steels and exotic alloys.

All inserts arrive in a compact protective case with foam slots that keep each insert organized and protected between jobs, helping you faster setup, less downtime, and safer storage. This kit is ideal for engineers, machinists, and technicians who need precise, repeatable external threads without guesswork.
