Eagle Tool Us ESP37572 Cable Installer Bit 3/8 in 72 in pneumatic accessory

Cable Installer Bit 3/8 in 72 in

The Eagle Tool US ESP37572 is a screw-point cable drill bit designed for electricians and low-voltage installers who pull wire through wood framing. Its 72 in overall length reaches deep into wall cavities and across ceiling bays without extension shafts. The 3/8 in cutting diameter creates a clean hole for multiple cable runs. This accessory fits standard 3/16 in hex chucks on pneumatic or electric drills.

Practical limits of the straight-flute design

The straight three-flute geometry removes chips efficiently in softwood but loads quickly in hardwood or engineered lumber, so drilling speed must be reduced. Maximum drilling depth is 70 in, leaving 2 in of shank engagement for chuck security. Powder coating resists surface corrosion yet wears off the cutting edges after repeated contact with abrasive materials. The 3/16 in shank diameter limits torque transmission compared to larger-shank bits.

Check your existing setup before ordering

Verify that your drill chuck accepts a 3/16 in hex shank and that the chuck jaws close fully on the three-flat section to prevent slip. Ensure the tool delivers sufficient low-speed torque for a 3/8 in bit at 70 in depth without stalling. Confirm the workpiece thickness does not exceed the 70 in effective drilling range. This bit is not suited for masonry, metal or nail-embedded lumber.
