Grade HS5120 Characteristics

HardStone HS5120 uses tin coating tuned for general machining on steel, cast iron. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

Features & Benefits

100% Genuine HardStone – Original product with full quality guarantee, traceable batch.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, cast iron interruptions.
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

General Machining of steel, cast iron 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.

Reminder: Holder rigidity, lead angle, and approach all influence how this insert wears. Pair with a holder rated for the same cutting forces.
