Itm 308fb7212-s Flex Drill Bit 1/2 in 72 in Screw Point

Product Description

The ITM 308fb7212-s is a flexible drill bit designed for drilling through wood framing, drywall, and other structural materials in finished or tight wall cavities. It measures 0.5 inches in diameter and 72 inches in length, giving installers the reach needed to work through deep wall sections and floor cavities without opening finished surfaces. The screw point tip allows fast, self-starting entry into wood and drywall without a pilot hole. Constructed from high speed steel, the flexible shaft bends to navigate corners and tight routing paths that rigid bits cannot reach.

This bit is a standard tool for alarm, low-voltage, and communications installers who need to route wire through framed walls, ceilings, and between floors. It is well suited to residential and light commercial retrofit work where access is limited and a flexible shaft is necessary to reach from one cavity to another. A fish hole on each end of the bit allows a pull string or wire to be attached and drawn back through the drilled path, simplifying wire-pull operations in concealed spaces.

Key Features

• 0.5-inch diameter screw point tip for self-starting entry into wood and drywall
• 72-inch overall length for reaching through deep wall and floor cavities
• Flexible high speed steel shaft bends to navigate tight corners and angled framing
• Fish hole on each end for attaching and pulling low-voltage wire or pull string
• Compatible with standard 3/8-inch or 1/2-inch chuck drill drivers

Compatibility

Designed as an OEM-style flexible drill bit for use with standard 3/8-inch or 1/2-inch keyed or keyless drill chucks commonly used in low-voltage, alarm, and communications installation work.

Installation Notes

This bit is typically installed and used by low-voltage technicians, alarm installers, and communications wiring contractors working under NEC Article 725 or 800 guidelines. Before drilling into wall or ceiling cavities, verify stud, joist, and utility locations to avoid contacting electrical conductors, plumbing, or gas lines. Use a variable-speed drill at reduced RPM when navigating bends to avoid overstressing the flexible shaft. Do not force the bit through material at sharp angles that exceed the natural flex radius of the shaft.
