Key item features

  • Accurate Starts: The drill bits feature a no-skate tip design, engineered to provide clean and precise starts for drilling operations.
  • Reduced Friction: A black oxide coating is applied to the bits, which effectively generates less friction during use.
  • Professional Application: Designed to meet the needs of contractors, electricians, and other professionals for general-purpose drilling.
  • Versatile Materials: Suitable for drilling in various materials including wood, plastic, and light-gauge metal.
  • Enhanced Durability: The combination of the tip design and black oxide coating contributes to a longer lifespan compared to standard drill bits.
  • Improved Grip: Bits measuring 3/16 inches and larger incorporate a three-flat shank design, promoting better gripping and preventing slippage.
  • Clean Holes: The split-point tip is specifically engineered to ensure accurate holes without any skating at the start.
