ETRH2-20 500W Rotary Hammer: Light, Affordable, SDS-Plus

Not every concrete job needs an 800W machine. The ETRH2-20 is our 500W rotary hammer - the entry point to real SDS-Plus drilling for DIYers, small contractors, and distributors who need a low-cost model in their catalogue. It drills 20mm holes in concrete and handles everyday 6-14mm fixing work without the weight or the price of a site-class machine.

Built in our Taizhou factory since 2002, the ETRH2-20 is available under your own brand through our OEM/ODM programme. It is one of the best-selling economy Rotary Hammers we ship to Southeast Asia, the Middle East, and Latin America.

Key Features & Benefits

• 1.7J SDS-Plus impact — Real piston-drive impact for concrete - a true rotary hammer, not a vibrating hammer drill. 1.7J is enough for 6-14mm anchors and cable clips.

• 500W motor, light body — Around 20% lighter than our 800W machines, so it is comfortable for overhead clips and one-handed work on ladders.

• SDS-Plus chuck — Keyless bit changes in seconds, with universal SDS-Plus bits from 6mm to 20mm available from any brand.

• Compact housing — Designed for toolbags and van racks - it earns its place on small jobs and in service work.

• Double-insulated body — Meets international electrical safety standards for household and light trade use in 110V or 220-240V markets.

• Factory-direct value — A genuine SDS-Plus rotary hammer at an entry price - the model you stock when the order needs a budget but not a toy.

Where the ETRH2-20 Earns Its Keep

• Home & small-job concrete fixing — Drilling 6-10mm holes for shelf brackets, curtain rails, TV mounts, and light anchors in brick and block - the daily reality of most buyers of this 500W rotary hammer.

• Electrical & plumbing clips — Fast clip and saddle fixing on cable runs, conduit brackets, and pipe hangers, where its light weight makes overhead work easier.

• Timber & steel drilling — Rotate-only mode drills wood and steel cleanly, so the ETRH2-20 covers framing and metalwork without a second drill.

• Workshop & service work — A lighter alternative to site hammers for bench fixing and equipment mounting in workshops and repair shops.

• Distributor entry SKU — The model you put in starter catalogues and price lists - real SDS-Plus performance at an economy price point.

ETRH2-20 vs Other ETpower Models

500W vs 800W: Be Honest About What You Need

If your work is mostly 6-10mm fixings in brick and block, a 500W rotary hammer saves money and weight. If you drill 12-18mm anchors in reinforced concrete every day, the 800W ETRH2-26 or 900W ETRH2-28 pays for itself in speed. We sell both - and we would rather tell you the smaller one is enough than oversell.

ETRH2-20 FAQ

1. Is a 500W rotary hammer enough for concrete?

For 6-14mm fixings in brick, block, and light concrete, yes. It is a true SDS-Plus piston hammer, not a hammer drill - that is the difference that matters.

2. What size hole can the ETRH2-20 drill?

Up to 20mm in concrete with a solid bit. It runs 6mm and 8mm fixing holes all day, and its optimum range is 6-14mm.

3. Can it chisel or remove tiles?

No - the ETRH2-20 has two modes (drill and hammer drill), not three. For tile and chisel work, step up to the 3-mode ETRH3-26.

4. What is the difference from a hammer drill?

A hammer drill vibrates the chuck; a rotary hammer drives the bit with a piston. On concrete, the rotary hammer is dramatically faster and less effort - 1.7J of true impact versus a few tenths of a joule of vibration.

5. Does it use SDS-Plus bits?

Yes - a universal 10mm SDS-Plus shank, so any SDS-Plus bit brand fits. Never put round-shank bits in an SDS-Plus chuck.

6. Can I get 110V?

Yes, 110V is available for North American and Japanese markets, plus 220-240V for Europe, the Middle East, and Asia. Specify at order.

7. What is the duty cycle?

40% intermittent duty - roughly four minutes of drilling per ten, which is normal for this class. It is a light-trade tool, not a demolition machine.

8. Do you offer OEM on the ETRH2-20?

Yes - logo, colour, packaging, and carton art are yours. We have produced this model for multiple private labels; send your volumes for pricing.
