Kyocera CCGT030104L-F TN60
Kyocera CCGT030104L-F TN60 is a superior cermet finishing insert with TiCN+NbC edge, positive geometry and ~0.4 mm corner radius. Delivers excellent surface finish and enhanced wear resistance in turning of steel & stainless. Perfect where quality & cost efficiency matter.
The Kyocera CCGT030104L-F TN60 is a high-performance finishing insert, engineered for machinists who demand precision, finish, and wear resistance. Made in the TN60 cermet grade (ceramic + metal composite), the insert’s microstructure is enriched with TiCN + NbC, giving it the toughness to resist edge degradation and the sharpness needed for mirror surfaces.
With a positive rhombic (80°) geometry, a clearance angle of ~7°, a ~0.4 mm corner radius, and effective cutting edge length of ~1.7 mm, this CCGT insert excels in steel and stainless steel finishing tasks — continuous or mildly interrupted cuts. Its left-hand orientation makes it suitable for many turning applications where direction matters.
Choosing this insert means: fewer insert changes, cleaner finishes, reduced machine idle, and lower cost per part. It’s a go-to choice for automotive, aerospace, die & mould, general engineering — anywhere finish matters as much as throughput.

Why It’s a Best Seller
-
Low wear / long tool life: TN60’s cermet composition delivers excellent wear resistance (especially flank wear), meaning fewer insert changes.
-
Better surface finish: Positive geometry + fine corner radius ~0.4 mm gives superior finish, especially for finishing passes.
-
Reduced downtime: With more stable cutting, less chipping, fewer re-setups, your machine stays productive.
-
Cost savings per component: Higher life + fewer rejects = lower cost per part.

Frequently Asked Questions
It works especially well on steel and stainless steels for finishing operations. It can handle light interruption but shines in continuous cuts. (TN60 cermet grade is built for wear resistance + toughness.)
Thanks to its fine corner radius (~0.4 mm) and positive geometry, you can expect very smooth finishes (low Ra values) when using appropriate feeds and speeds in finishing cuts.
While actual life depends on cutting conditions, many users see significant increases (often 30–50 % or more) in life when switching from standard uncoated carbide to TN60 cermet in finishing Steel/STainless, due to better wear resistance.
It’s optimized for finishing. For heavy interruptions or roughing, a more robust geometry or larger corner radius would be better. TN60 can tolerate mild interruptions, but best kept for clean finish passes.
