Flexible Drill Bit for Wire Pulling,3/4 x 54 in. Flex Auger Drill Bit | Guide Ball Kit Included; Black Steel Shaft, Auger Head, Fish-Eye Hole & 3-Flat Shank for Pulling Wires in Walls and Studs

Material & Size: 3/4" head diameter x 54" long with a 1/4" shank diameter. It features a #65 carbon steel cutting head and a spring steel shank. This is an auger-type drill bit, equipped with a self-feeding threaded tip, cutting edges, and flutes for chip removal.
Flexibility: This flexible auger drill bit has a non-slip three-flat grip. It has been heat-treated for optimum strength and memory. All bits will flex to some degree; shorter bits are not as flexible as longer ones.
Simple Operation: The hole in the top end allows for pulling wire. The flexible shaft enables unique self-feeding drilling, making it suitable for drilling holes down the length of a wall and through hidden studs without damaging wallboard, plaster, or any exterior finish.
Strength & Durability: The screw point installer bit features ultra-sharp threads for better pulling power and faster drilling speeds. It moves quickly through obstructions to easily drill and fish wire through existing walls.
RPM Rule of Thumb: The larger the diameter of the drill bit, the slower the RPM should be. (A larger bit may grab and bind. Slow it down and try again. )
Guide Ball Kit: When the fixing ring is positioned correctly (its diameter is larger than the drill bit for easy movement), it can be secured using the included L-wrench.
Applicable Scenario: This auger drill bit fits most standard size power drills. It is suitable for use on walls, kitchen counters, sidewalks, recessed lighting, and camera mounts
