If you’re tired of slow, hand-cranked assembly with tiny Allen wrenches, the Narwhal Ball End Hex Head Drill Bit Set is a practical way to move those same hex fasteners over to a power tool. It’s built around a hex shank design and includes both SAE and metric sizes so you can cover a wide range of furniture hardware, shop fixtures, and general DIY tasks.

The bits are made from chrome molybdenum (CR-MO) steel with a black oxide finish, and the set is designed to work with either a standard drill or an impact driver. Each size is laser measured (per the brand) for fit, and the magnetic tips help keep the bit engaged while you work.

  • 24-piece set with SAE and metric ball end hex (Allen) sizes
  • Magnetic tipped bits for easier engagement during fastening
  • Chrome molybdenum (CR-MO) steel construction with black oxide finish
  • Hex shank design; compatible with standard drills and impact drivers
