Eagle Tool US EHS25018 Flexible Drill Bit

The Eagle Tool US EHS25018 is a serrated flexible drill bit designed for cable installation tasks. It features a 1/4 in drill bit size with a straight shank that includes three flats for secure chuck grip. The overall length measures 18 in with a shank diameter of 3/16 in and a shank hex size of 3/16 in. A powder-coated finish helps protect the bit during use.

Installers needing extended reach in cavities

Electricians and low-voltage installers who need to drill through studs or joists from a distance will find the 18 in length useful. The maximum drilling depth of 16 in supports deep penetration in wood framing. Users requiring larger hole diameters or rigid bits for metal drilling should look at other options. The flexible shaft is not suited for precision drilling in hard materials.

Behaviour during extended drilling sessions

The powder coating reduces friction and resists wear when the bit is run continuously through multiple studs. Flexible shaft construction absorbs vibration, which helps maintain control during sustained operation. Heat build-up is managed by the serrated cutting edges clearing chips efficiently. The three-flat shank prevents slippage in the chuck even under prolonged torque.

Questions about this item

What chuck size do I need on my drill to fit the 3/16 in hex shank?

Use a drill with a 3/16 in hex chuck or a compatible quick-change adapter to secure the shank.

Will the 18 in overall length reach through the 2×4 studs I already have in the wall?

The bit offers a 16 in maximum drilling depth, so it clears standard 3.5 in stud cavities with length to spare.

How can I confirm the serrated tip is cutting cleanly once I start drilling?

Watch for steady chip ejection and a smooth, round hole without wandering or excessive vibration.
