VP15TF Miracle Coating Technology
The VP15TF grade utilizes a proprietary PVD Miracle Coating (Al-Ti-N) that provides extreme hardness and heat resistance. It is the long-tail finishing choice because it prevents adhesive wear and "built-up edge" when machining gummy materials like stainless steel or soft carbon steels, ensuring consistent surface finish and long tool life.
FM Chipbreaker: Finish Mastery
The FM chipbreaker is specialized for precision. It features a sharp cutting edge and specialized geometry to control chips at very low depths of cut. This is vital in precision boring, where a long chip can damage the internal surface of a part. The FM breaker curls chips tightly for safe evacuation from narrow bores.
