We've got a crew starting a retrofit next week on 6-inch reinforced slab, and the corded hammers are just too much hassle running extension cords across three floors, so I ordered the DCZC22B kit to see if it can keep up with the core drilling and anchor setting we need daily.
It's a brushless 20V setup pushing 420W with 2.2J impact energy, which is pretty much what you'd expect form a decent mid-range rotary hammer—the no-load speed tops out at 1400 rpm and impact frequency hits 4500 per minute, so it's not fastest out there but it's steady enough for 22mm concrete holes or 13mm steel without bogging down, and the 4.0Ah batteries (you get two) usually last about 45 minutes of continuous hammering, give or take.
For demolition mode it actually works better than I thought for chipping out old mortar or light break-up work, but don't push it for rebar-heavy pours or you'll burn through bits fast—the 2.6kg weight makes it manageable overhead but the vibration dampening is only so-so, so your guys will want gloves for extended use, and the included depth gauge and auxiliary handle are decent but the carry case is flimsy, honestly.
Anyway, I'm ordering a spare charger and a couple extra batteries (usually 2-3 week lead time, but our company have stock on the kit itself) because teh MOQ on the tool-only option wasn't worth it for this trial run.
We don't have a strict MOQ for this model — you can order single units or bulk, whichever fits your needs. For larger quantities, we can offer better pricing and faster lead times.
Yes, the DCZC22B comes with CE and RoHS certifications, and we can share the documentation on request. Just let us know what you need for your market.
With the included charger, each 4.0Ah battery takes about 60-90 minutes to fully charge. You get two batteries in the package, so you can cycle them and keep working.
The 2.2J impact energy and brushless motor give it good punch for concrete, but hitting rebar at full 22mm can stall it. For rebar-heavy work, we recommend using a smaller bit or stepping up to a larger SDS model.
We recommend keeping everything in the included carrying case in a dry, cool place — avoid high humidity or direct sunlight. The case has slots for the drill, both batteries, charger, and all the accessories, so nothing gets lost.
