Flexible Drill Bit 1/2 in 54 in

This flexible drill bit is designed for routing cables through walls, ceilings and floors. The 54 inch overall length and 1/2 inch diameter suit electricians and installers who need extended reach in confined cavities. A serrated screw point starts holes cleanly in wood framing. The powder coated finish resists corrosion during repeated use.

Serrated Screw Point and Three Flat Shank

The serrated screw point pulls the bit forward while cutting, reducing the force required to start each hole. A straight shank with three flats locks securely in a drill chuck, preventing slippage when torque spikes. The 3/16 inch hex shank fits standard drill drivers without an adapter. These features combine to speed up long cable pulls.

Maximum Drilling Depth 52 in

The effective drilling depth is limited to 52 inches, so through holes deeper than that require a different approach. Flexible shafts can wander off line over long spans, making precise exit points harder to guarantee. The bit is intended for wood framing only; it will not cut masonry, metal studs or concrete. Users needing deeper or straighter bores should consider rigid auger bits or conduit.

Questions about this item

Will the 3/16 in shank need replacement after repeated flexing?

The 3/16 in hex shank is integral to the bit; no separate shank replacement is offered.

Does the 52 in maximum drilling depth limit how deep I can bore?

Yes, the bit is designed for a maximum drilling depth of 52 in.

Does the powder-coated steel run hot during continuous drilling?

The powder-coated steel body dissipates heat normally for flexible cable bits; no special cooling is required.
