HUAALIUCHE 36" Flexible Installer Drill Bit for Pulling Wires in Walls, Ceilings, and Sidewalks, 1/2" Auger with Screw Point & Fish Eye, 3/16" 3-Flat Shank for Wood & Conduits, with Storage Tube — Open-Box, 13% Off

IMPORTANT NOTICE: When the drill bit encounters significant resistance or jamming, use a reciprocating in-and-out motion to advance it gradually. DO NOT forcefully push or apply excessive pressure. Overexertion or excessive speed/torque may cause the long drill bit to deform or even snap. This is an inherent physical characteristic of long flexible drill bits, not a product defect. Max Bend: 60° (emergency use only)，Optimal Bend: < 30°. Not suitable for use on masonry, concrete, or metal studs.

VERSATILE FOR WIRE INSTALLATION: Designed for drilling through walls, ceilings, and floors during electrical and low-voltage wire runs. The fish eye hole near the tip helps guide wire through hidden spaces with less disruption to finished surfaces.

FLEXIBLE SPRING STEEL FOR TIGHT SPACES: Built from durable spring steel to help the bit bend and maneuver through wall cavities, between studs, and around common obstructions. Ideal for long-reach routing where a standard short bit cannot easily reach.

SECURE 3-FLAT SHANK FOR STABLE DRILLING: The 3/16 inch shank with a 3-flat design helps provide a secure hold in the chuck and dependable torque transfer during drilling, reducing slippage and supporting more controlled operation.

36 INCH OVERALL LENGTH WITH PROTECTIVE TUBE: This long flexible drill bit features a 36 inch overall length and a 1/2 inch auger head for deep wall access and wire-routing jobs. Includes a high-strength clear protective tube for added storage protection, helping reduce surface wear and oxidation over time.

【COMPLETE KIT WITH PROTECTIVE STORAGE TUBE】 Maximize value and tool longevity with the only kit that includes a high-strength, impact-resistant transparent tube! This tube shields your installer drill bit from dust, impact, and kinks, while the sealed caps prevent oxidation. Easily identify your bit size at a glance, keeping you organized and job-ready. 【DUAL HOLE & SCREW-TIP FOR ULTIMATE EFFICIENCY】 Features a self-feeding screw tip for faster boring through wood and drywall. Our exclusive dual cable hole design (at both ends!) allows you to feed wires from either direction without flipping the flex bit, saving crucial time and effort on every installation job. 【PREMIUM SPRING STEEL FOR SUPERIOR FLEXIBILITY】 Crafted from higher-quality spring steel, our flexible drill bit offers exceptional durability and controlled flexibility. It's engineered to bend and maneuver through tight spaces inside walls and between floors without breaking, ensuring reliable performance for years to come. 【ANTI-SLIP SHANK & REINFORCED FISH EYE FOR SAFETY】 The 3/16" hex shank with 3-flat anti-slip design guarantees a secure lock in any chuck, eliminating dangerous slippage. The reinforced fish eye hole near the tip provides superior strength for pulling wires inside wall cavities from either direction with complete confidence. 【ENGINEERED FLEXIBILITY & VERSATILE LENGTHS】 Professionally engineered for optimal performance: 36" model max bend: 60° (emergency use only); Optimal bend: ≤30°. Available in multiple lengths (36", 48", 54", 72") to suit any project. The auger-style flute ensures fast drilling and easy chip ejection for running wires through walls, ceilings, and conduits. 【Tips】 1.Use a low speed and a powerful corded drill. Control the torque to prevent overheating, jamming, or damage. 2.For a sharper edge, new bits can be ground to remove the coating. Sharpen them regularly as they dull with use to extend their life.
