Flexible Drill Bit for Cable Installation
The Eagle Tool US EHS50018 is a flexible drill bit designed for cable installers and electricians. Its 18 inch overall length and serrated tip allow drilling through studs and joists inside wall cavities. The 1/2 inch diameter creates holes suited for pulling wire or data cables.
Upgrade from Standard Twist Bits
Standard twist bits cannot navigate bends between framing members, so this flexible shaft replaces them when access is limited. The jump is worth it for retrofit work where removing drywall is not an option. A 1/4 inch shank with three flats locks securely in a drill chuck without slipping.
Practical Limits of the Flexible Shaft
The flexible shaft permits curves but reduces control over hole straightness compared to rigid bits. Maximum drilling depth is 16 inches, leaving a short margin from the 18 inch overall length. Powder coating resists corrosion yet adds no structural stiffness. The 3/16 inch hex shank section limits torque transmission on very dense hardwoods.

Questions about this item
What shank size fits the 1/2 in EHS50018 flexible drill bit?
The shank diameter is 1/4 in with a 3/16 in hex, so it fits standard 1/4 in chucks and quick-change holders.
How do I install the bit without it slipping in the chuck?
Align the three flats on the straight shank with the chuck jaws and tighten firmly; the flats prevent rotation under torque.
When should I replace this flexible drill bit?
Replace it when the serrated cutting edges no longer pull through cleanly or the powder coating wears off the 16 in drilling section.
