The Original Korloy FMM300R-03 PC9030 is a premium Single-Ended Multi-Functional Insert designed for high-precision Grooving, Side-Turning, and Parting-off. Optimized for Stainless Steel (M) and Heat-Resistant Alloys (S), the 3.0mm width provides excellent structural integrity. Unlike double-ended inserts, the single-ended FMM design features a longer clamping surface, ensuring the insert remains rock-solid during lateral profiling. The PC9030 PVD coating is world-renowned for its ability to resist built-up edge (BUE) and maintain a sharp cutting edge in gummy materials.
Stainless Steel Master: PC9030 is Korloy’s flagship PVD grade. When machining 304 or 316 stainless steel, this grade prevents material welding on the insert tip, ensuring high surface quality and dimensional consistency in every part.

Pro Guide: PC9030 vs. NC3030
When should you choose the PC9030 grade for your FMM 3mm insert?
The Precision Specialist. Ideal for Stainless Steel and Superalloys. It features a sharper edge and a smoother coating to prevent chip sticking.
The Steel Specialist. Optimized for general and alloy steels. While tougher for heavy interrupted cuts in steel, it is more prone to built-up edge when cutting stainless.
Machinist's Pro Tip: For the best results in 316 Stainless, use a Constant Surface Speed (CSS) program and high-pressure coolant. The FMM300R-03 PC9030 excels when it is kept cool and the chip load is consistent during side-turning moves.
Packaging: 10 pieces per box.
