About Kyocera WN 80° Trigon Negative Inserts
The WN 80° trigon (three-sided) negative geometry with 6 cutting edges per insert provides the best edge economy among negative-rake inserts. The 80° point + negative rake balance strength and edge count for general steel and stainless work.
Key advantages of the WN family:
- 6 cutting edges per insert — best edge economy of any negative geometry
- Strong edge support — 80° point + negative rake for general work
- Versatile — general steel, stainless, and cast iron in one geometry
- Better than CN/SN for cost-per-edge due to 6 edges vs 4
The WN family includes sub-designations:
- WNMG — 80° trigon negative w/ hole + molded chipbreaker. The workhorse for economy general turning.
- WNMM — 80° trigon negative w/ hole + molded chipbreaker + thicker section for heavy roughing.
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 WN Insert
Selecting the correct WN insert involves three decisions:
- Material → Grade: Steel → PR930 / PR1125 / PR1535. Stainless → CA5525 / CA6525. Cast iron → CA4515. Steel finishing → TN60.
- Operation → Chipbreaker: General → TM. Heavy → TMM. Finishing → TS.
- IC size → Tool holder: WNMG 08 (12.7 mm) → DWLNR/L 08. WNMG 13 (15.875 mm) → DWLNR/L 13.
Tip: For general steel work, start with WNMG080408-TM T9125-equivalent grade. For stainless, use CA5525 grade.
Frequently Asked Questions
Are these genuine Kyocera original inserts?
Yes — all 56 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 WN and other turning geometries?
WN 80° has 6 cutting edges vs 4 for CN 80° (rhombic) and 4 for SN 90° (square). WN provides the best edge economy with comparable edge strength.
What does the IC size mean in this WN family?
IC sizes: WNMG 08 = 12.7 mm, WNMG 13 = 15.875 mm. Larger IC for heavier work.
What tool holder do I need for WN inserts?
WN 80° trigon negative inserts fit standard DWLNR/L, PWLNR/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 WN compare to the negative-rake alternative?
WN is a negative-rake insert. Compare with positive-rake WB/WP: WN has stronger edge but higher cutting forces. Use WN for general work with edge economy; use WB/WP for finishing + thin sections.
