This review is from: DEWALT DW5230 3/8-Inch x 6-Inch Carbide Hammer Drill Bit (Tools & Home Improvement)
Since I didn't know much about drilling holes in rocks, I researched other reviews on Amazon before making a choice. Because I'm not a contractor, there wasn't a reasonable justification to go for a SDS drill. I have a V-28 Milwaukee cordless hammer drill, and found that the DeWalt carbide hammer drills had numerous strong reviews. This bit was quite good - I drilled 6 holes, each about 3-4 inches deep in solid boulders. The bit performed well - using water for cooling and dust removal - granite clearly took more effort than softer stone, but the bit remained effective even after the granite holes. I'd easily buy a bit in this series again for other projects.
