For optimal drilling speeds, the two-stage flute design features a variable helix pattern that quickly moves debris away from the contact zone. Plus, the two sharp, carbide-cutting edges deliver clean, round holes for secure anchor installation. These bits are made in Germany and are GUARANTEED TOUGH - so tough that we are offering a NO BREAK GUARANTEE*. If you have our bits, we have your back. From the Manufacturer DEWALT DW5440 1/2-Inch x 16-Inch x 18-Inch ROCK CARBIDE SDS Plus Hammer Bit Review: Great bit for drilling deep holes in concrete! - This carbide hammer bit is exactly what I needed for drilling some deep holes into concrete. The shaft is machined very well and there is very little wobble to it. After drilling a bunch of holes back to back and heating up the bit, there was zero damage to the carbide tip. Was very happy to see this and it should hopefully last a very long time. This also does a great job at removing all of the dust from the hole saving time from having to pull the drill back and forth. The roundness of all of the holes has been great (as long as I drill straight). Would highly recommend and buy again! Review: Super tough - I don't think I could break this if I tried. It cut very well in my foundation. The end that engages in a drill is obviously designed for a professional grade hammer drill and the notches cause it to be off center in a standard chuck. I cut the very end off leaving on the smooth shank for my chuck to grab and now this is a perfect standard masonry bit. Love it! ## Features - Strong core: SDS max bits have tapered core for bit strength and maximum durability, especially when drilling deep holes - Aggressive material removal: Two stage flute design with variable helix pattern of DEWALT SDS hammer drill bits allows for efficient debris removal - Clean, round holes: Two sharp cutting edges for true holes - Wear mark indicator: For accurate diameter of holes - NO BREAK GUARANTEE: If your bit fails for any reason while the wear mark is still visible, we'll replace it (excludes: DW5400, DW5401, DW5401B25) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000224YV | | Best Sellers Rank | #728,732 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #714 in Rotary Hammer Drill Bits | | Brand | DEWALT | | Brand Name | DEWALT | | Customer Reviews | 4.7 out of 5 stars 976 Reviews | | Cutting Diameter | 0.5 Inches | | Finish Type | Steel | | Finish Types | Steel | | Global Trade Identification Number | 00028874054400 | | Item Dimensions | 1.88 x 0.5 x 21.25 inches | | Item Weight | 6.4 ounces | | Item dimensions L x W x H | 1.88 x 0.5 x 21.25 inches | | Manufacturer | DEWALT | | Material | Carbide | | Material Type | Carbide | | Model | DW5440 | | Number of Flutes | 2 | | Number of Pieces | 1 | | Part Number | DW5440 | | Set Name | 1 | | Shank Type | SDS | | Surface Recommendation | Alloy Steel | | Tool Flute Type | Spiral | | UPC | 028874054400 | | Unit Count | 1.0 Count | | Warranty Description | 1 Year Full Warranty | ## Images ![SDS+ Hammer Bit, Rock Carbide, 1/2-Inch by 16-Inch by 18-Inch (DW5440) - Image 1](https://m.media-amazon.com/images/I/61IhuV2IAML.jpg) ![SDS+ Hammer Bit, Rock Carbide, 1/2-Inch by 16-Inch by 18-Inch (DW5440) - Image 2](https://m.media-amazon.com/images/I/71CV+zG-i4L.jpg) ![SDS+ Hammer Bit, Rock Carbide, 1/2-Inch by 16-Inch by 18-Inch (DW5440) - Image 3](https://m.media-amazon.com/images/I/81APh09PH7L.jpg) ![SDS+ Hammer Bit, Rock Carbide, 1/2-Inch by 16-Inch by 18-Inch (DW5440) - Image 4](https://m.media-amazon.com/images/I/612KuPQyhxL.jpg) ![SDS+ Hammer Bit, Rock Carbide, 1/2-Inch by 16-Inch by 18-Inch (DW5440) - Image 5](https://m.media-amazon.com/images/I/61GP8RaLXEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great bit for drilling deep holes in concrete! *by M***N on January 20, 2020* This carbide hammer bit is exactly what I needed for drilling some deep holes into concrete.

The end that engages in a drill is obviously designed for a professional grade hammer drill and the notches cause it to be off center in a standard chuck. I cut the very end off leaving on the smooth shank for my chuck to grab and now this is a perfect standard masonry bit. Love it! ### ⭐⭐⭐⭐⭐ Fantastic value for hammer drill holes through swimming pool wall *by C***L on November 18, 2020* Wooks better than expected. I drilled a small, shallow starter hole in the wall. My 1/2" hammer drill quickly punched thru a 14" cast gunite wall. The bit also worked its way around a rebar in the wall. The bit was still sharp after the job. To install a pipe thru this hole requires a pipe less than 1/2" od. I used a polyethylene hose for my wires, but a copper pipe would have worked well for plumbing. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/1825177-sds-hammer-bit-rock-carbide-1-2-inch-by-16](https://www.desertcart.ie/products/1825177-sds-hammer-bit-rock-carbide-1-2-inch-by-16) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-02*
