High Precision Finish：Mirror‑like surface, tight tolerance, reduces secondary grinding.
Monolithic CBN：Excellent wear resistance, stable and consistent performance.
Dry/MQL Friendly：Suitable for dry cutting or MQL, eco‑friendly and cost saving.

Product Advantages
Exceptional Hardness & Heat Stability ：High temperature resistance minimizes wear in high‑speed machining.
Cost Effective ：Longer tool life and less downtime lower per‑part cost.
Superior Surface Quality：Grading‑level finish eliminates secondary processing.
Eco‑Friendly：Multi‑edge design reduces waste; supports dry/MQL.

1.S-type single-edged blade tips specialize in high-precision machining. Coatable CBN edges enhance tool longevity, ideal for precision components；

2.Eight-edged tool tips optimize high-volume production. With multiple cutting edges, they dramatically reduce tool wear and promote eco-friendly manufacturing.

3.Monolithic CBN Inserts - Superior Wear Resistance for Maximum Tool Performance

Notes: Edge rounding W=0.15mm; customizable for different workpiece materials.

Application Scenarios

Hard Turning：HRC45+ hardened steel (bearings, gears, shafts) replace grinding. HRC45
Aerospace Alloys：Inconel and superalloys for turbine blades, engine parts.
Cast Iron Machining ：Brake discs, engine blocks with high efficiency.
Mold & Die：Semi‑finishing & finishing of precision molds.
