ETBRH01-26 21V Cordless Rotary Hammer — SDS-Plus, 3.0J Battery-Powered Concrete Drilling

The ETBRH01-26 brings genuine rotary hammer performance to a 21V cordless platform: 3.0 joules of impact energy, 0–1,100 rpm and 0–3,600 bpm, with an optimum drilling range of 6–18mm in concrete. For electricians, installers, and maintenance crews who drill anchors all day in places without power — rooftops, stairwells, new-build shells — it delivers corded-class results without a generator or extension lead.

It runs on a 21V battery system that shares cells and chargers across the wider ETpower cordless range, so a crew can standardize on one battery platform for drills, impact drivers, and grinders. Factory-direct from Taizhou XuLi Machinery with OEM/ODM support for distributors building their own cordless line.

Key Features & Benefits

3.0J impact energy on battery— matches our 800W corded ETRH2-26 for anchoring work in 6–18mm concrete.
21V battery platform— cross-compatible with other ETpower 21V cordless tools; fewer batteries to buy, less to carry.
SDS-Plus chuck— keyless bit changes, full range of 6–26mm bits and chisels.
0–1,100 rpm variable speed— full control for small-diameter precision holes and soft-start into hard aggregate.
Multi-mode selector— drill / rotary hammer / hammer-only for drilling, anchoring, and light chiselling.
Compact & lightweight— noticeably lighter than a corded breaker, ideal for overhead and ladder work.

Applications: Where a Cordless Rotary Hammer Earns Its Keep

1. Anchor drilling on live sites with no mains power

New-build shells, mezzanine installs and rooftop PV mounting — anywhere a generator is impractical, the ETBRH01-26 drills anchors straight from the battery.

2. Maintenance & facility work

Fixing racking, signage, and machinery anchors in operating warehouses where trailing cables are a safety hazard.

3. Interior fit-out & renovation

Occupied apartments and offices: no cables to trip tenants, lower noise than a breaker, and fast clean-up between rooms.

4. Scaffold & façade work at height

Lighter than a corded tool and no cable management on ladders or suspended platforms — a major safety advantage.

5. Tile removal & chasing (hammer-only mode)

Flat and point chisels in hammer-only mode handle bathroom tile removal and shallow wiring chases.

Corded vs Cordless Rotary Hammer: Honest Comparison

	ETBRH01-26 (21V cordless)	ETRH2-26 (800W corded)
Impact energy	3.0J	3.0J
Sustained heavy drilling	Limited by battery runtime	Unlimited (40% duty cycle)
Best use	Remote sites, at-height, maintenance	High-volume anchoring, shop work
Weight	Lighter	Heavier
Cost	Higher (battery system)	Lower

Many professional crews own both: cordless for access and convenience, corded for volume. Distributors can package the two as a combo offer.

Frequently Asked Questions

Q1: How many holes will one battery drill?

With a 2.0Ah pack, expect roughly 40–60 anchor holes of 8×60mm in average concrete; the 4.0Ah option doubles this. Runtime depends heavily on concrete hardness and bit quality.

Q2: Is 21V enough for real concrete work?

Yes — the 3.0J impact energy matches our 800W corded model. What the battery limits is volume, not capability. For all-day high-volume anchoring, corded remains more economical.

Q3: Do the batteries work with other ETpower cordless tools?

Yes. The 21V platform is shared across our cordless drills, impact drivers/wrenches, grinders, and saws — one charger per crew.

Q4: Is it brushless?

Brushed and brushless configurations are both available for OEM orders; brushless versions offer longer runtime and motor life at a higher price point. Contact us for the option sheet.

Q5: Can it chisel as well as drill?

Yes — hammer-only mode with SDS-Plus chisels handles tile removal and shallow chasing. It is not a substitute for a dedicated demolition breaker.

Q6: What charger is included?

Standard kits ship with a 21V fast charger (EU/UK/US plug per destination market). Custom kits (bare tool / 1 battery / 2 battery) are available for OEM orders.

Q7: Can we get it under our own brand?

Yes — OEM logo printing, custom colors, and retail-ready packaging are standard services. ODM modifications (housing, switch, kit contents) are supported for volume orders.

Q8: What markets is it certified for?

CE for the EU; battery pack certifications (UN38.3, MSDS) are provided for air/sea shipping. Market-specific requests can be discussed during quotation.
