Alpha Drill - Gold Series Extra Long 3.3mm X 315mm

A Gold Series drill bit is a high-performance cutting tool typically coated with a gold-colored titanium nitride (TiN) finish for enhanced durability and wear resistance. This coating reduces friction, increases heat resistance, and extends the lifespan of the drill bit, making it ideal for drilling into hard materials like steel, aluminum, wood, and plastics. The Gold Series drill bits are known for their precision, strength, and longevity, often used in professional and industrial applications where reliability and performance are essential.
