  • Flexible 72 in reach accesses tight cavities

Flexible Drill Bit 1/2 in Diameter 72 in Length

The Eagle Tool US EHS50072 is a serrated cable installer bit designed for pulling wires through cavities. Its 72 in overall length reaches deep into walls or ceilings for long runs. The 1/2 in drill bit size creates holes suited to common cable bundles. A 1/4 in shank diameter fits standard drill chucks for quick changes.

Maximum Drilling Depth 70 in Shank Hex 3/16 in

Practical reach stops at 70 in of drilling depth, leaving the last 2 in for chuck engagement. The straight shank with three flats prevents rotation in the chuck under high torque. A 3/16 in hex section allows use with impact drivers or bit holders when needed. Powder coating reduces friction but wears off with heavy abrasion.

Powder Coated Finish 1/4 in Shank Diameter

The powder coated surface resists rust during storage and eases withdrawal through insulation. The 1/4 in shank diameter suits most 3/8 in and 1/2 in drill chucks without adapters. Three flat sides give a positive grip so the bit will not slip when boring dense timber. Flexible shaft behaviour demands steady pressure to avoid kinking.

Questions about this item

Should I choose the 72-inch length or a shorter flexible bit for my cable pull?

The 72-inch overall length provides a maximum drilling depth of 70 inches, so select this version when you need to reach through long wall cavities or ceiling spaces.

What does the 1/2-inch diameter mean when I am drilling through studs?

It cuts a 1/2-inch hole, sized for pulling typical data or low-voltage cables through wooden framing members.

Will the 1/4-inch straight shank with three flats fit my 3/8-inch drill chuck?

Yes, the 1/4-inch shank diameter fits any standard 3/8-inch or 1/2-inch keyed or keyless chuck, and the three flats prevent slipping under torque.
