HardStone TNMG160404HQ HS8125 – Carbide Insert

The HardStone TNMG160404HQ carbide insert, graded HS8125 and coated with tin, excels in general machining applications on steel and stainless steel workpieces, where its triangular shape enables effective cutting and minimal vibration. This substrate and coating combination allows for a strong balance between wear resistance and toughness, making it suitable for a wide range of machining tasks. With its robust properties, the TNMG160404HQ is particularly well-suited for tackling demanding general machining jobs that require consistent results and predictable tool life.

Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, stainless steel interruptions.
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

General 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 HardStone tooling users worldwide

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.
