Enhanced Durability: Our 2-piece bit holder is made of impact-resistant, flexible, and unbreakable nylon that withstands even the toughest jobsites. Hold Bits or Screws to Your Tool: Easy access for you to reach the bit, screw, nuts, and you don't need to go back to replace the nuts, especially when working at heights with ladders. Magnetic Bit Holder: Thanks to the strong magnetic attraction force, the bits are firmly held in place by a super-strong neodymium magnet without coming loose. The magnetism does not diminish even after multiple uses. Secure Attachment: The bit holder is attached to the impact driver with a 3M adhesive that creates a strong and reliable connection to the drill housing and does not come loose during operation.
