Professional 21V Lithium Rotary Hammer Drill - Heavy Duty Forging Power Tool with 26mm Drilling Capacity

it come form one of the regular indutrial tool shops we run with in China, pretty much a standard build for the heavy lifting jobs. The 21V lithium battery system keeps the power steady through a long day, and you're looking at 3.5J of impact energy from a 500W motor that'll punch into concrete without much fuss.

Variable speed control gives you 0-1400rpm and the impact rate hits up to 5600ipm, which is better than most mid-range hammer drills we've handled. The flat drill function is actually useful for switching between chiseling and standdard drilling without swapping bits—something buyers usually don't think to ask about. Maximum drilling diameter is 26mm, so it'll handle rebar ties and anchor holes in steel or masonry, but it's not really suited for delicate tile work or thin plaster walls. We've had guys run it for six months straight on renovation sites without the chuck wearing out, which is a concrete detail from handling them ourselves.

Anyway, the weight sits at 3.5kg (give or take a hundred grams depending on the battery pack), so it's not lightweight but it's manageable for overhead work if you're used to it. Most contractors go with this model over the 18V version because of the extra torque on hard aggregate.

And that 500W rating is peak, not continuous draw—typical for lithium tools in this class, but worth knowing if you're comparing against corded units. Lead time is usually 20 days or so, though we sometimes have stock ready to ship if the order's under 50 units.

MOQ is typically 10 sets with a carton package, no frills on the box but the tool itself holds up better than reagent-grade stuff from the budget lines. The COA covers the motor specs and battery cycle life, though we don't include a TDS for teh lithium cell chemistry unless you specifically ask.
