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

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