About Kyocera DN 55° Diamond Negative Inserts
The DN 55° diamond negative geometry balances the strong edge support of negative rake with the profile clearance of a narrower point angle. With 4 cutting edges per insert, DN inserts are the workhorse for profiling + general turning combined operations.
Key advantages of the DN family:
- Best of both worlds — stronger edge than TN, better profile clearance than CN
- 4 cutting edges per insert — good economy
- Versatile — profiling, contour turning, and general work in one geometry
- Negative rake edge support — handles interrupted cuts better than positive inserts
The DN family includes sub-designations:
- DNMG — 55° diamond negative w/ hole + molded chipbreaker. The workhorse for profiling + general turning.
- DNMA — 55° diamond negative w/ hole + no chipbreaker. For special-purpose or cast iron work.
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 DN Insert
Selecting the correct DN insert involves three decisions:
- Material → Grade: Steel → PR930. Stainless → CA5525. Steel finishing → TN60.
- Operation → Chipbreaker: General → TM. Finishing → TS. Heavy → TH.
- IC size → Tool holder: DNMG 11 (12.7 mm) → DDJNR/L 11. DNMG 15 (15.875 mm) → DDJNR/L 15.
Tip: For general steel profiling, start with DNMG150408-TM T9125-equivalent grade. For stainless, use CA5525.
Frequently Asked Questions
Are these genuine Kyocera original inserts?
Yes — all 23 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 DN and other turning geometries?
DN 55° is between TN 60° (more edge strength) and VN 35° (more profile clearance). DN is the versatile middle-ground choice for combined profiling + general turning work.
What does the IC size mean in this DN family?
IC sizes: DNMG 11 = 12.7 mm, DNMG 15 = 15.875 mm. DNMG 15 is the more common general-purpose size.
What tool holder do I need for DN inserts?
DN 55° diamond negative inserts fit standard DDJNR/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 DN compare to the negative-rake alternative?
DN is a negative-rake insert with stronger edge support than positive-rake DC inserts. Use DN for combined profiling + roughing; use DC for finishing and thin sections.
