VP15TF Miracles Coating
The VP15TF grade features a micro-grain carbide substrate with a high-performance AlTiN Miracle PVD coating. This grade is the industry standard for stable machining across a wide spectrum of materials. It offers superior resistance to built-up edge (BUE) and chemical wear, ensuring longevity in lathe turning operations.
FS Super-Finish Breaker
The FS chipbreaker is designed with a high-positive rake angle and an ultra-sharp cutting edge. It excels at breaking chips even at low depths of cut, providing excellent chip evacuation. This prevents the "bird-nesting" of chips that can scratch workpiece surfaces during critical finishing passes.
