Our final application was completing some access holes into the machine room, again using a 1″ bit. Having the right tool for the job is always important, but perhaps more so when you’re holding your arms over your head 20 feet in the air, on scaffolding, boring holes. It gets more appealing when you do the math and calculate the savings in labor time and just plain sweat equity. For the uninitiated, a tool like this will make its $390 cost begin to look quite appealing. Whereas the hammer drill took its time and required a lot of effort on our part to get the holes drilled, the same size bit in the DeWalt DCH213L2 spun into the concrete – almost like butter. The amount of fatigue the hammer drill gave us over the rotary hammer was astounding. This was rough overhead drilling – 24 holes in all – and we had begun the job with a traditional 18V hammer drill for comparison. These were smaller holes of just 1/4″ in diameter and the DeWalt DCH213L2 powered through them with nearly reckless abandon, save for the depth rod which let us drill each hole and then stop at just the right depth. ![]() In another location we ended up having to drill some holes in reinforced concrete ceiling beams (this seemed to be a trend with us) in order to suspend some pendant-style loudspeakers from the ceiling of a gymnasium. As with any concrete drilling job, it you want to keep the work area clean, we recommend a dust extraction system as this tool will work quickly – and just as quickly generate an enormous amount of dust that needs to be evacuated. ![]() That probably shouldn’t come as a surprise to anyone. With these larger diameter holes, the job was tough and it definitely took a bit longer than when we were doing smaller-diameter Tapcon pre-drilling. It didn’t take any time at all before the bit sank in and we were boring our first hole. The rotary hammer began easily, with minimal walking along the face of the concrete as we began. Eager to begin, we loaded up a 1″ Bosch SDS-plus Bulldog bit into the DeWalt Rotary Hammer and set to work. ![]() Unfortunately, with a building that was originally constructed in the 1940’s, you’ve just got a lot of concrete to penetrate to get from one end to the other. The classrooms were used for an inner-city after school program here in town and the rooms were being upgraded with a hard-wired fiber-based network. We needed to drill several 1″ access holes through reinforced concrete in order to run some network cable into a machine room and through to some classrooms. While the DCH213L2 is primarily designed for use with 5/32″ to 1/2″ bits (with which it will drill tons of holes), our first job was somewhat more demanding. DeWalt DCH213L2 20V Max SDS Rotary Hammer Testing and Use The tool also comes with a depth rod for setting how far the drill will go when performing repetitive tasks like pre-drilling anchors in a wall or drilling into concrete floors for Tapcon installation. The mode switch is located on the left of the tool and is a large oversized dial which was easy to adjust with gloved or bare hands. The SDS Plus chuck worked very well and we were able to quickly load and release bits with a minimum amount of fuss. ![]() Rotate the handle of the DeWalt DCH213L2 20V Max SDS Rotary Hammer to a more convenient position to avoid covering the LED light with your hand
