New Grade IC5500 for Steel Drilling
Highlights
ISCAR is launching IC5500 - a new MTCVD grade for drilling carbon and alloyed steel (ISO P)
The new grade features a new substrate and a new coating.
The new multi-layer and special post-coating treatment substantially prolongs tool life and strengthens insert toughness, improving operational reliability.
The new grade will be available on square inserts that are used on
DR drills:
3340386 SOMX 060304-DT IC5500
3340385 SOMX 070305-DT IC5500
3340384 SOMT 09T306-DT IC5500
The inserts made from
IC5500 are aimed to be used only in the outer pocket of
DR drills (the inner insert should be an
IC908 or
IC808 PVD coated insert).
New IC5500 MTCVD Coating Features
Post coating treatment
Alpha Alumina
Intermediate layer
TiCN layer
Adhesion layer
Substrate
Total Thickness
Reduces residual stresses and improves chipping resistance
Reduces crater wear and improves chipping resistance.
Thick Al2O3 improves thermal cracks resistance
Enhances the adhesion between Al2O3 layer and TiCN layer
in the bonding area, improving peeling resistance
Improves flank wear resistance
Enhances the adhesion with the substrate, preventing peeling during machining
Improved matching between coating and substrate
Improves toughness and wear resistance
Features and Benefits
- Coating:
A new upgraded MTCVD coating:
Improved toughness, chipping resistance and thermal cracks resistance
- Post coating treatment:
Improved toughness and chipping resistance
- Combination of new coating and new treatment:
Better performance and process reliability
