The MOQ on the RH-BS26 is 100 units, lead time about 25 days or so depending on carton availability—usually our company have stock, but confirm lead time if you need faster.
Power is 800W, impact rate hits 4000bpm with 3J energy, so it chews through 24mm concrete without breaking a sweat, and teh flat drill function basically lets you shave edges.

5kg is manageable for an 8-hour shift, but some guys say it's a bit heavy for overhead work—just so you know. One concrete detail: the gearbox is cast iron, not alloy, so it holds up better on continuous use, but that adds the weight.
You're getting 3J impact energy at 900rpm unloaded, which is tighter tolerance than most 800W drills in this class—better for the variable speed control when you're switching form wood to steel (13mm and 32mm bores respectively).

Speed control is actually smooth through the whole range, not just a trigger ramp-up—I've handled hundreds, but there's a minor click in the first 10 use cycles, it's normal after break-in.
Anyway, COA and CE certs are included per unit, packaing is single blister with drill and side handle—no case unless you specially request it.
Our standard MOQ is 500 units per model, but we can discuss smaller trial orders depending on your needs.
Lead time is usually 30 to 45 days after order confirmation, depending on the quantity and current production schedule.
Yes, we can provide CE, RoHS, and other relevant certifications upon request, along with a factory inspection report.
We can adjust the speed control settings or modify the flat drill mechanism for OEM orders, but that requires a minimum quantity and some lead time for tooling changes.
Each unit comes in a color box with foam inserts, and we recommend storing them in a dry warehouse at room temperature to avoid moisture damage.
