Long Flexible Drill Bit Extension, 4.5 FT with Hex Key and Spare Screws

Material & Size: The drill bit extension features a 9/16" head diameter x 54" length with a 1/4" shank diameter. It is made of #65 carbon steel cutting head with a spring steel shank, suitable for all quarter-inch shank cable bits and three-flat shank drill bits.

Flexibility: With a three-flat non-slip grip on the chuck end, the flex shank installer drill bit extension has been heat-treated for optimal strength and memory. While all extensions will flex to some extent, the shorter bits are less flexible compared to longer ones.

Easy to Use: The hex shank features a power groove to reduce slippage, allowing you to place and tighten screws with confidence even in challenging areas. This extension is perfect for use with the YY-LC 3/4 Flexible Drill Bit.

Applicable Scenario: This drill bit extension is compatible with most standard size electric drills and can be utilized for various applications, including wall punching, kitchen counter installations, sidewalk drilling, recessed lighting installation, and high-place cleaning tasks.
