This bit is best for all types of wood. Aggressive and self feeding auger point. Three flat non-slip grip on the chuck end. Flexible spring steel shank. Wire fishing accommodation holes in the head and shank. 1/2-inch head diameter, 3/16 inch shank diameter, and overall length is 72-inch. Review: Be careful. Goes through everything. Awesome tool. - Top quality and literally tougher than nails. My first time out drilling up into the attic from a cutout for a switch box I went right through a double top plate. Went right through nails (or something made of metal) wit no problem, no binding or anything. I used a 1/2 inch right angle drill which helped. Unfortunately I got it I got it crooked and came out near the ceiling in the next room. Lesson learned. Be careful. Couldn't be happier with it but it's not magic. Review: Permanent addition to my house - The bit works just fine. If anything it flexes a bit too much. I was drilling up a wall from the basement. That wall has a stairway attached to one side. I thought I had drilled through the stringer and was headed up. Turns out the bit was going along the he bottom of the stringer at an angle and what I was drilling through were studs. When I realized what was happening and tried to back it out, the bit got bound up and the extension I was using came off the end. This bit will live in the house longer than I will. The second one of these I bought along with a 72” extension did the job wonderfully. I now have 4 Ethernet cables running from my basement to the second floor office with room to spare. Live and learn. ## Features - Aggressive and self feeding auger point - Heat Treated spring steel shank with wire fishing accommodation holes in the head and shank. - Best flexibility in 72-inch shank - Made in the USA - Add a Quick Switch Hex to adapt to a Quick Change chuck, part number ETHXKIT187 - Compatible with 3/16-inch shank extensions, part numbers EX18736 and EX18754 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DNEEJ0C | | Best Sellers Rank | #336,553 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #241 in Auger Drill Bits | | Brand | Eagle Tool US | | Brand Name | Eagle Tool US | | Customer Reviews | 4.4 out of 5 stars 744 Reviews | | Cutting Angle String | 135 degrees | | Cutting Diameter | 0.5 inches | | Finish Type | Uncoated | | Finish Types | Uncoated | | Global Trade Identification Number | 00850078004758 | | Included Components | EA50072 | | Item Dimensions | 72 x 0.5 x 0.5 inches | | Item Weight | 1.1 pounds | | Manufacturer | Eagle Tool US | | Material | hardened steel, spring steel | | Material Type | hardened steel, spring steel | | Model | EA50072 | | Number of Flutes | 2 | | Number of Packs | 1 | | Number of Pieces | 1 | | Part Number | EA50072 | | Point Style | Auger Style | | Shank Type | 3-Flat | | Surface Recommendation | Wood | | Tool Flute Type | Spiral | | UPC | 850078004758 | | Unit Count | 1 Count | | Warranty Description | 30 day manufacturers warranty | ## Images ![Made in The USA, Eagle Tool US EA50072 Flex Shank Installer Drill Bit, Auger Style, 1/2-Inch by 72-Inch, 3/16-Inch Shank - Image 1](https://m.media-amazon.com/images/I/41H5arm0GqL.jpg) ![Made in The USA, Eagle Tool US EA50072 Flex Shank Installer Drill Bit, Auger Style, 1/2-Inch by 72-Inch, 3/16-Inch Shank - Image 2](https://m.media-amazon.com/images/I/719qBeYZOSL.jpg) ![Made in The USA, Eagle Tool US EA50072 Flex Shank Installer Drill Bit, Auger Style, 1/2-Inch by 72-Inch, 3/16-Inch Shank - Image 3](https://m.media-amazon.com/images/I/61VP+fC-PnL.jpg) ![Made in The USA, Eagle Tool US EA50072 Flex Shank Installer Drill Bit, Auger Style, 1/2-Inch by 72-Inch, 3/16-Inch Shank - Image 4](https://m.media-amazon.com/images/I/61FLWGMXbwL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Be careful.

I was able to complete my recess light project with this flex drill bit. Found a review on youtube telling to drill it carefully going forward and backward to avoid the drillbit getting stuck in joist. That way it worked really well. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/28927084-made-in-the-usa-eagle-tool-us-ea50072-flex-shank](https://www.desertcart.uy/products/28927084-made-in-the-usa-eagle-tool-us-ea50072-flex-shank) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-09-15*
