Cable Installer Bit for Electricians
The Eagle Tool US EA50072 is a screw-point auger bit designed for pulling cable through wood framing. Its 72 inch overall length lets electricians reach through multiple stud bays from a single entry point. The 1/2 inch cutting diameter creates a clean hole for standard residential wiring. The straight shank with three flats locks securely into a drill chuck.
Practical Limits of the Auger Design
The bit achieves a maximum drilling depth of 70 inches, which defines the longest single pass possible without extension. The 3/16 inch shank diameter and hex size limit the torque that can be applied before the shank becomes the failure point. The powder-coated carbon steel resists corrosion but will dull faster in abrasive engineered lumber than hardened alternatives. Chip ejection relies on the auger flutes clearing the deep hole.
Build Quality and Daily Implications
The carbon steel construction with powder coating provides durability for repeated job-site use. The three-flat shank prevents slippage in keyless chucks during high-torque starts. At 72 inches the bit requires ample workspace and two-handed control to maintain alignment through the cut. The straight profile allows easy coupling with a pulling grip for wire installation immediately after drilling.

Questions about this item
Which length and diameter combination fits my job?
This bit is 72 in overall with a 1/2 in cutting diameter and a 3/16 in hex shank, giving a maximum drilling depth of 70 in.
What does the 72 in overall length mean once the bit is chucked in a drill?
You gain roughly 70 in of usable drilling depth after the shank seats in the chuck, letting you reach through studs or joists in a single pass.
What shank standard does the 3/16 in hex use and what does it limit?
The 3/16 in straight hex with three flats fits standard drill chucks and quick-change holders, capping the maximum shank diameter to 3/16 in for compatibility.
