About Kyocera TN 60° Triangle Negative Inserts
The TN 60° triangle negative geometry is one of the most versatile turning geometries. With 3 cutting edges per insert, 60° point angle, and negative rake, TN inserts are the workhorse for general turning and interrupted cuts.
Key advantages of the TN family:
- Versatile — 60° point provides balance of strength + profile clearance
- Multiple edge styles — TNMG (molded), TNMM (thicker), TNGG (ground), TNGA (no chipbreaker)
- Strong edge support — negative rake handles interrupted cuts
- Multiple IC sizes — 9.525 / 12.7 / 15.875 mm for various work scales
The TN family includes sub-designations:
- TNMG — 60° triangle negative w/ hole + molded chipbreaker. The workhorse standard.
- TNMM — 60° triangle negative w/ hole + molded chipbreaker + thicker section. For heavy roughing.
- TNGG — 60° triangle negative ground sharp edge for finishing work.
- TNGA — 60° triangle negative w/ hole + no chipbreaker. Ceramic or special-purpose.
Kyocera Corporation (Kyoto, Japan) is one of the world's leading manufacturers of CNC cutting tools, with over 60 years of tooling expertise. The Kyocera PR series (CVD-coated steel), TN series (cermet), PV series (PVD-coated stainless), CA series (CVD stainless / cast iron), and KW series (uncoated aluminum) represent decades of grade development.

How to Choose the Right Kyocera TN Insert
Selecting the correct TN insert involves three decisions:
- Material → Grade: Steel → PR930 / PR1125 / PR1535. Stainless → CA5525 / CA6525. Cast iron → CA4515. Hardened → LX11 ceramic.
- Sub-designation → Operation: General → TNMG. Heavy → TNMM. Finishing → TNGG. Special → TNGA.
- IC size → Tool holder: TNMG 11 (9.525 mm) → DTJNR/L 11. TNMG 16 (12.7 mm) → 16 mm seat. TNMG 22 (15.875 mm) → 22 mm seat.
Tip: For general steel work, start with TNMG160408-TM T9125-equivalent grade. For stainless, use CA5525 grade.
Frequently Asked Questions
Are these genuine Kyocera original inserts?
Yes — all 116 products in this catalog are 100% genuine Kyocera originals manufactured by Kyocera Corporation in Kyoto, Japan. Each insert ships in original Kyocera factory packaging with full traceability.
What is the difference between TN and other turning geometries?
TN 60° is between CN 80° (strongest edge, 4 edges) and SN 90° (strongest, square). TN has 3 cutting edges vs 4 for CN/SN, but with narrower 60° point for better profile clearance.
What does the IC size mean in this TN family?
IC sizes: TNMG 11 = 9.525 mm, TNMG 16 = 12.7 mm, TNMG 22 = 15.875 mm. Larger IC = thicker insert.
What tool holder do I need for TN inserts?
TN 60° triangle negative inserts fit standard DTJNR/L, MTJNR/L external turning holders tool holders. Browse our turning tool holder catalog for compatible options.
What grade should I choose for stainless steel?
For stainless steel work, Kyocera recommends CA5525 (CVD M-grade) or PV720 (PVD grade) — both provide superior wear resistance and edge security on 304/316 stainless. Choose CA5525 for heavier roughing; choose PV720 for finishing operations.
How does TN compare to the negative-rake alternative?
TN is a negative-rake insert. Compare with positive-rake TC triangle: TN has stronger edge but higher cutting forces. Use TN for general work with interrupted cuts; use TC for thin sections.
