CCGT03S102L-F VP15TF
Miniature Finishing Specialist | Miracle PVD Coating | Swiss-Lathe Grade
Technical Breakdown
VP15TF Grade (Miracle PVD Carbide): This grade features a high-toughness micro-grain carbide substrate coated with a proprietary Al-Ti-N Miracle Coating. Unlike brittle cermets, VP15TF is designed to handle interrupted cuts and prevents thermal cracking. It is the gold standard for machining Stainless Steel, Alloy Steel, and Super Alloys where edge security is paramount.
L-F Chipbreaker (Left-Hand Finishing): A precision-ground, sharp-edge geometry optimized for Ultra-Light Depths of Cut. The "F" series design ensures that even at miniature scales, chips are broken and evacuated efficiently, preventing "bird-nesting" and protecting the high-quality surface finish of your workpiece.

Shop Small-Series HoldersPro-Tip: VP15TF vs NX2525
VP15TF (PVD Carbide): Your most versatile choice. Use this for interrupted cuts, stainless steel, and when the setup isn't 100% rigid. It is significantly tougher than cermet.
NX2525 (Cermet): Switch to cermet only for continuous finishing in steel to achieve a mirror finish. Cermet will chip if used in heavy interrupted cuts or gummy alloys where VP15TF excels.
