Grade AC6145M Performance Profile

Operators running steel, stainless steel with the Sumitomo AC6145M typically report stable wear progression rather than catastrophic edge loss. The diamond system is the reason: it slows abrasion at the rake face while keeping the substrate from softening at the cutting zone.

Features & Benefits

100% Genuine Sumitomo – Original product with full quality guarantee, traceable batch.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
Diamond Coating – Superior wear resistance and extended tool life under continuous load.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Rough Machining of steel, stainless steel in production CNC lines
Pairs well with through-coolant setups for chip evacuation
Holds dimensional tolerance over multiple indexings (insert)
Designed for shop conditions typical of Sumitomo tooling users worldwide

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Entry-tier pricing makes this a low-risk option for trialing Sumitomo tooling on a new material.

Tip: Match this insert to a holder whose seat matches the ISO designation. If you’re unsure, send us the holder model and we’ll confirm compatibility before shipping.
