Grade HS6120 Performance Profile

Operators running steel, copper, composites with the HardStone HS6120 typically report stable wear progression rather than catastrophic edge loss. The tin 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 HardStone – Original product with full quality guarantee, traceable batch.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
tin Coating – Superior wear resistance and extended tool life under continuous load.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

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

Buying Considerations

Pack of 10 — sized for typical production runs without leaving idle inventory on the shelf. Entry-tier pricing makes this a low-risk option for trialing HardStone tooling on a new material.

Note: Compatible tool holders sold separately. Please confirm insert-holder seat compatibility (e.g. ISO seat designation) before ordering.
