Cut more parts, change inserts less often.
The Kyocera CCGT040102R-F TN60 is engineered for high-precision finishing of steel and stainless-steel components, combining Kyocera’s advanced cermet grade technology (TN60) with a positive rake geometry that delivers exceptional wear resistance, toughness, and mirror-like surface finish.

Designed with an 80° diamond-shaped (CCGT) geometry, this insert ensures low cutting forces and smooth chip evacuation — ideal for finishing outer and inner diameters where dimensional accuracy and surface quality are critical. The TN60 grade features a refined cermet substrate that maintains hardness at high temperatures and resists crater wear, making it perfect for consistent finishing across long production runs.

Hook / Attention Line

“Cut more parts, change inserts less often – the new Kyocera CCGT040102R‑F TN60 delivers longer tool life, faster cutting and lower cost per component.”

Key Features & Specs

  • Geometry: 80° diamond shape (CCGT size) with a positive rake angle – designed for finishing outer diameter/inner diameter turning. MISUMI+1

  • Insert type: With hole, double-sided, two usable edges (standard in this family) 

  • Grade: TN60 – a general-purpose cermet grade optimized for steel & stainless-steel finishing with superior wear resistance and toughness. 

  • Material/coating: The TN60 family falls under “cermet for steel & stainless steel machining” in the Kyocera catalogue; no specific PVD / CVD mention for this part number but grade TN60 is the recognised cermet finish for finishing. 

  • Cutting applications: Specifically intended for finishing turning operations (outer/inner diameter) on steel, stainless steel, cast iron and certain heat-resistant alloys and titanium alloys per the CCGT “for finishing” series.

  • Other spec details: For the part number CCGT040102… the configuration shows Work Material = Steel / Stainless Steel / Cast Iron; radius options nose R = 0.2 mm or 0.4 mm; rε (corner radius) = 0.2 mm in that variant

Why It’s a Best Seller:

  • Less downtime: With the TN60 grade’s excellent wear resistance and toughness, tool changes are less frequent, meaning you spend more time cutting and less time stopped.

  • Better surface finish: The combination of the 80° diamond shape and positive rake geometry tailored for finishing ensures high-quality surface finishes straight off the machine.

  • High wear resistance: TN60 cermet material offers a great balance of hardness plus toughness – allowing you to push finishing cuts on steel and stainless where standard grades might wear quickly.

  • Cost per component advantage: Because you can maintain higher cutting parameters for longer, and achieve consistent surface finish, your effective cost per part drops.

  • Trustworthy brand: From the global manufacturer Kyocera, so you’re backed by catalogue-grade specs and global supply.

🏭 Application Industries

  • Automotive: finishing transmission housings, shafts, brake components (steel & stainless)

  • Aerospace: finishing smaller steel or stainless components requiring excellent surface integrity

  • Die & Mould: finishing steel tooling plates and inserts requiring minimal rework

  • General engineering: turning operations on steel/stainless in job-shops and production machining environments

  • Heavy equipment & capital goods: robust enough for tougher steel grades needing high-finish turning

Frequently Asked Questions

This insert is optimised for steel and stainless-steel finishing, and according to the catalogue also covers cast iron and certain heat-resistant or titanium alloys.

TN60 is a cermet grade from Kyocera defined as a “general purpose cermet with superior wear resistance and toughness for steel & stainless-steel finishing.”

The geometrical designation “CCGT” refers to an 80° diamond-shape positive rake turning insert (with hole) suitable for finishing. The specific nose-radius options include R 0.2 mm or 0.4 mm per the variant.

Because of the high wear resistance and stable performance of the TN60 grade, you can maintain cutting parameters for longer, reduce insert changes and maintain consistent part quality — this lowers downtime and scrap/rework costs, reducing overall cost per piece.

While it is designed primarily for finishing (based on the CCGT “for finishing” series designation) and optimised for steel/stainless finishes, in less demanding environments it may handle semi-finishing. For heavy roughing, however, you may be better served by a roughing-grade insert.
