Eagle Tool Us Flexible Drill Bit 1/2in Dia x 54in L pneumatic accessory

SKU CH-MS4E-WCSH4

A 54-inch flexible drill bit with a 1/2-inch diameter reaches 52 inches deep for cable installation

  • Split-point tip starts holes cleanly without wandering
  • 54 in overall length reaches deep cavities and wall cavities
  • 1/2 in drill bit diameter bores large holes for cable pulls
  • 1/4 in shank with three flats locks securely in drill chucks
  • Powder-coated finish resists corrosion during extended use

Flexible Cable Installer Bit

The Eagle Tool US EHS50054 is a split-point drill bit designed for cable installers and electricians pulling wire through framed walls. Its 54-inch overall length and 1/2-inch diameter allow deep reach between studs and joists without removing drywall. The flexible shaft navigates bends inside cavities where rigid bits cannot follow.

Powder-Coated Steel With 1/4-Inch Shank

A powder-coated finish protects the steel body during repeated contact with wood framing and insulation. The straight shank features three flats and a 1/4-inch diameter with a 3/16-inch hex section to prevent slipping in drill chucks or quick-change adapters. Maximum drilling depth reaches 52 inches, leaving room for chuck engagement.

Upgrade From Short Auger Or Spade Bits

Installers replacing 16-inch or shorter auger bits gain the ability to drill through multiple bays in a single pass. The jump is worth it when fishing cable across long spans or through insulated cavities where a flexible shaft follows the path. Buyers who need a rigid bit for precision joinery or metal drilling should choose a different tool.
