Eagle Tool Us cable installer bit 9/16 in 72 in overall length

SKU CH-F3ZD-5V9RS

A 72 in cable installer bit with a 9/16 in drill size, 1/4 in hex shank and 52 in maximum drilling depth

  • 9/16 in bit drills wide cable paths
  • 72 in overall length reaches deep cavities
  • 52 in maximum drilling depth covers long runs
  • 1/4 in hex shank fits standard chucks
  • Powder-coated carbon steel resists wear

9/16-Inch Cable Installer Bit

This 9/16-inch cable installer bit is designed for electricians and installers pulling wire through wood framing. The screw point starts holes cleanly while the straight shank with three flats locks securely in a drill chuck. Powder coating adds surface protection during extended use. The 72-inch overall length reaches through deep cavities without extensions.

Thermals, Noise and Power Draw

As a non-powered cutting accessory, the bit generates no heat, noise or electrical draw of its own. Friction heat depends on drill speed, feed pressure and wood density rather than the bit itself. Operators control temperature and sound by adjusting the power tool’s trigger and maintaining sharp cutting edges.

52-Inch Maximum Drilling Depth

The 52-inch maximum drilling depth determines whether this bit spans the full distance between access points in a single pass. Buyers needing to bore through thicker assemblies or multiple joined timbers will find the reach insufficient. The 1/4-inch hex shank fits standard quick-change chucks but limits compatibility with larger collets.

Questions about this item

How do I install the 1/4 in hex shank into my drill and what step do people get wrong?

Insert the 1/4 in hex shank fully into the chuck and tighten securely on the three flats; the common mistake is not seating the flats completely, which allows the bit to slip under load.

What maintenance or replacement will the carbon steel 9/16 in bit need after extended use?

The powder-coated carbon steel cutting edges will dull over time; resharpen the screw point and flutes or replace the bit when drilling performance drops in wood or masonry.

What limit appears first when drilling continuously at the maximum 52 in depth with this 72 in overall length bit?

Chip evacuation becomes the limiting factor; the three-flute design can pack with debris at full depth, requiring frequent withdrawal to clear the hole and prevent binding.
