Premium HSS Super Long Boy Drill Bits – 18″ Long

Premium High Speed Super Long Boy Drill Bit – 18″ Long

Premium High Speed Super Long Boy Drill Bits are built for deep drilling and long-reach applications where standard jobber and aircraft-length drill bits cannot reach. Manufactured from solid M2 High Speed Steel, these 18″ long drill bits deliver the strength, rigidity, and durability required for demanding fabrication, repair, and industrial work.

Each bit features a 15″ flute length for reliable chip evacuation and stable tracking at full depth. The 118° split point starts quickly, reduces walking, and provides clean entry in steel, non-ferrous metals, wood, and composite materials. Heavy-duty production geometry ensures consistent performance under repeat use without premature wear.

Sizes over 1/2″ diameter include a 1/2″ reduced shank, allowing compatibility with standard drill chucks while maintaining drilling stability in large-diameter applications.

These Super Long Boy drill bits are ideal for fabricators, maintenance crews, equipment repair, construction, and industrial applications that require true extended reach without extensions or adapters. When access is limited and depth matters, this is the drill bit designed to get the job done.
