Initial comparison accepted · broader validation pending

Case 01

CNMM190624 heavy turning

Large bearing-ring rough turning against a premium-brand reference insert.

Target: CNMM190624 heavy roughing insert
Candidate: CVD-coated carbide equivalent, approx. 20 μm coating
Workpiece: 100CrMoMnSi8-4-6 bearing steel · approx. Ø900 mm ring
Process: HESSAPP 1200 · continuous rough turning · coolant
Cutting data: Vc ≈ 220 m/min · f ≈ 0.8 mm/rev · ap ≈ 5–6 mm
Initial result: 10-piece sample delivered approximately equivalent tool life under the same parameters
Control point: Further industrial tests must keep the same source, grade and process logic

Sample candidate available

Case 02

Automotive cast-iron milling

Target: RCKT1204MO-KM 1020-style insert
Material: GS51 / GS54 cast iron
Operation: Ap ≤ 1 mm
Candidate: YG-series substrate · PVD AlTiN
Demand signal: Approx. 100 pieces/month
Stage: Candidate selected for industrial test; not yet a validated replacement

Sintered stainless steel interrupted milling

Geometry and application verification

Case 03

Sintered 316L interrupted milling

Target: R300-0828E-PL 1010-style CoroMill 300 insert
Material: Sintered AISI 316L stainless steel
Operation: Interrupted cutting · approx. 0.3 mm removal
Cutter: D ≈ 63 mm · 8T / 10T · insert-only replacement
Potential: Approx. 400–500 pieces/month
Stage: Specific geometry candidate under verification; not a standard ISO round insert

What the cases prove

Three different technical challenges

The value lies in matching the replacement method to the project—not forcing one universal grade across unrelated applications.

Heavy turning validation

Requires toughness, coating thickness, edge preparation and strict sample-to-production consistency.

Automotive cost-down

Requires predictable performance, stable supply and a commercial case at repeat monthly volume.

Special milling geometry

Requires cutter compatibility and careful verification because the insert is not a generic ISO round shape.
