Flexible Drill Bit for Cable Routing

The Eagle Tool US ESP37518 is a flexible drill bit designed for pulling wire or cable through walls, ceilings and floors. Its 18 in overall length and 3/8 in diameter suit electrical and data installers who need reach in confined cavities. The screw-point tip starts holes cleanly in wood framing without walking.

16 in Maximum Drilling Depth

The critical specification is the 16 in maximum drilling depth, which sets the practical limit for through-hole work in studs or joists. A 3/16 in hex shank with three flats locks securely into a standard drill chuck or quick-change adapter, preventing slip under torque. Powder coating reduces friction and resists corrosion during extended use.

Shank Geometry and Coating Benefits

The straight shank with three flats delivers positive drive engagement, so the bit will not spin in the chuck when the screw point bites hard. Powder coating lowers drag while the bit flexes around obstacles, helping maintain a straight bore path. No additional accessories or software are included with this single bit.

Questions about this item

What does the 16 in maximum drilling depth mean when I am using the bit?

You can bore up to 16 in into the workpiece before the flutes run out of clearance.

How does the 3/16 in hex shank limit the chucks I can use?

The 3/16 in hex fits any 3/8 in or larger three-jaw chuck and most quick-change adapters.

Will the 18 in overall length fit between standard wall studs?

At 18 in long it clears typical 16 in on-centre stud bays with room to manoeuvre.
