Review: Excellent Drill Bit Set for Tough Jobs - As someone who frequently takes on various DIY projects, the DeWalt DW5470 5 Piece Rock Carbide SDS Plus Drill Bit Set has proven to be a reliable and valuable addition to my tool collection. I recently used these bits for a few home renovation tasks, including drilling into concrete and masonry, and they performed admirably. One thing that stood out immediately was how efficiently these bits cut through tough materials. The rock carbide tips stayed sharp and made clean holes with minimal effort. This set really shines when dealing with hard surfaces where other bits might struggle or wear out quickly. The durability of these bits is impressive. Even after multiple uses, they show little signs of wear, which is reassuring when you have ongoing projects. I’ve used them for installing anchors for heavy shelving in my garage, and they handled the job without any issues. What I particularly appreciate is the SDS Plus shank design. It ensures a secure fit in my drill and prevents slipping, which makes the drilling process smoother and more controlled. This feature is especially beneficial when precision is crucial. However, the storage case could be a bit sturdier. It does its job, but a more robust case would be a nice touch to keep the bits organized and protected. These drill bits have met and exceeded my expectations, making difficult drilling tasks much more manageable. If you're in need of a reliable and durable drill bit set, this one is a solid choice for any DIY enthusiast. ## Features - Rock carbide tip for longer bit life - Elongated four flute Helix for faster material removal - Increased steel prevents breakage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000224YX | | Best Sellers Rank | #61,044 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #49 in Rotary Hammer Drill Bits | | Brand | DEWALT | | Brand Name | DEWALT | | Customer Reviews | 4.7 out of 5 stars 2,308 Reviews | | Cutting Angle String | 3E+1 Degrees | | Cutting Diameter | 15.88 Millimeters | | Finish Type | Silver | | Finish Types | Silver | | Global Trade Identification Number | 00028874054479 | | Included Components | Dewalt - DW5447 Y | | Item Dimensions | 15.25 x 1.87 x 0.5 inches | | Item Type Name | Dewalt - DW5447 Y | | Item Weight | 0.49 Pounds | | Manufacturer | DEWALT | | Material | Carbide | | Material Type | Carbide | | Minimum Bore Diameter | 0.63 Inches | | Model | DW5447 | | Number of Flutes | 4 | | Point Style | Taper Point | | Shank Type | SDS-Max | | Surface Recommendation | Alloy Steel | | Tool Flute Type | Spiral | | UPC | 028874054479 | | Unit Count | 1.0 Count | | Warranty Description | 1 Year Full Warranty | ## Product Details - **Cutting Angle String:** 3E+1 Degrees - **Cutting Diameter:** 15.88 Millimeters - **Finish Type:** Silver - **Material:** Carbide - **Shank Type:** SDS-Max ## Images ![DEWALT DW5447 Hammer Bit - Image 1](https://m.media-amazon.com/images/I/51uqpxYLP0L.jpg) ![DEWALT DW5447 Hammer Bit - Image 2](https://m.media-amazon.com/images/I/21n5XNjaJaL.jpg) ![DEWALT DW5447 Hammer Bit - Image 3](https://m.media-amazon.com/images/I/31Mhxsk13CL.jpg) ![DEWALT DW5447 Hammer Bit - Image 4](https://m.media-amazon.com/images/I/51ZtQK9bIPL.jpg) ![DEWALT DW5447 Hammer Bit - Image 5](https://m.media-amazon.com/images/I/61-F+1LXrpL.jpg) ## Questions & Answers **Q: how deep can this bit drill into concrete** A: You can drill to a depth of 6-inches. **Q: What does the acronym SDS stand for?** A: SDS stands for "Slotted Drive System". **Q: Are these compatible? dewalt d25263k d-handle sds rotary hammer with shocks, 1-1/8"** A: Yes, this is compatible with model D25263K **Q: Will using running water to flush the hole add to the life of the drill and improving drilling speed, or will water be bad?** A: In 30 years I've never heard of using water and I've put these bits to the test drilling 20+ holes in a hour or less. You're chipping "rock", not cutting metal. Imo water would just gum up the bit, the hole, and makes mess! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Durable and Precise SDS Plus Bits Set *by Z***A on February 14, 2026* The DEWALT SDS Plus Bits Set (DW5470) is perfect for drilling into concrete, brick, and masonry.
