T9115 Grade Performance
The T9115 grade is a flagship Tungaloy CVD coating designed for stable and efficient steel turning. It uses a specialized alumina coating that provides a high-heat barrier, allowing for increased cutting speeds without edge deformation. This long-tail keywords industry favorite ensures that your CNC machining operations stay productive for longer periods with minimal insert changes.
PS Chipbreaker for Precision
The PS Chipbreaker is specifically ground for finishing. It is designed to handle light depths of cut and low feed rates, which are often necessary to achieve a superior surface finish in precision machining. It effectively breaks chips into small "C" shapes to prevent surface marring.
Recommended Cutting Parameters
Target Material: Steel (P) Finishing:
-
Cutting Speed (Vc): 180 - 350 m/min (590 - 1150 SFM)
-
Feed Rate (f): 0.03 - 0.15 mm/rev
-
Depth of Cut (ap): 0.1 - 1.0 mm
*Note: Due to the 0.2mm radius, avoid heavy feeds to prevent tip breakage.*

Technical Q&A
Q: Why choose the 0.2mm radius (CCMT060202)?
A: The 0.2mm radius allows for sharper corners and reduces cutting resistance, which is essential for thin-walled parts and fine finishing.
Q: Can I use this for boring small holes?
A: Yes! This is a very popular choice for small-diameter boring bars (SCLCR06) due to its light cutting action.
Q: What is the T9115 coating?
A: It is a CVD (Chemical Vapor Deposition) coating that provides high hardness and thermal stability, ideal for high-speed steel turning.
Machining Tip: Finishing Stability
For the absolute best results in precision machining, ensure your tool overhang is as short as possible. The CCMT060202-PS is highly efficient, but stability in the setup is key to leveraging the high-speed benefits of the T9115 CVD grade.
