Fractional/Self-Starting, TiN 3/16" - 1/2" - Unibit

The Unibit UN2T Fractional/Self-Starting step drill bit is engineered for the rigorous demands of professional automotive and industrial applications. This robust tool efficiently creates clean, accurate holes ranging from 3/16" to 1/2" in various thin materials, providing precision and extending tool life for technicians and mechanics. Featuring a durable Titanium Nitride (TiN) coating and a self-starting tip, it optimizes workflow and enhances productivity in high-demand environments.

Key Features

• Self-Starting, Non-Skid Tip: The precision-ground tip eliminates the need for center punching, enabling quick and accurate starts on curved or uneven surfaces, saving valuable time during critical tasks.
• Titanium Nitride (TiN) Coating: A hard, low-friction Titanium Nitride coating significantly enhances surface hardness and lubricity, extending tool life and improving drilling performance in high-wear conditions.
• Multiple Hole Sizes in One Bit: This versatile step drill bit consolidates six common fractional hole sizes (3/16", 1/4", 5/16", 3/8", 7/16", 1/2") into a single tool, streamlining your kit and reducing changeover time across various applications.
• Professional-Grade Construction: Crafted from industrial-grade high-speed molybdenum steel and heat-treated for maximum durability, ensuring sustained performance under rigorous professional use.
• 3-Flatted Shank: The three-flatted shank design ensures a secure, non-slip grip in drill chucks, preventing slippage and maintaining consistent torque for reliable and safe operation.
