Key Features

• Made in USA: Manufactured to stringent quality standards for consistent performance and durability.
• Steel Blue Nanocomposite Coating: Provides superior hardness and reduced friction, leading to a 40% increase in tool life compared to uncoated bits, even in challenging materials.
• No Center Punch or Pilot Hole Required: The self-centering design allows for immediate and accurate drilling, saving technicians valuable time and effort.
• 3-Flats on Shank: For sizes 3/16" and above, including this 5/16" bit, the three-flat shank prevents slippage in drill chucks, ensuring stable operation and optimal torque transfer.
• 135° Split Point Tip: This aggressive tip geometry penetrates quickly and cleanly, minimizing "walking" on the workpiece for precise hole placement.
