How to choose countersink coating? TiN, TiAlN, AlCrN differences?
TiN (gold) is versatile for low-to-mid speed machining; TiAlN (purple-grey) resists high temperature for high-speed dry cutting; AlCrN (black) is wear and corrosion resistant for stainless steel and high-temperature alloys. Lihao Technology offers multiple coating options with recommendations based on workpiece material.
