Frequently Asked Questions (FAQs)

Q: What materials can I drill with the DongCheng DCZC04-24 Rotary Hammer?

The tool is optimized for drilling into concrete, masonry, stone, steel, and wood. With a maximum drilling diameter of 24mm in concrete, 13mm in steel, and 28mm in wood, it handles most heavy-duty construction and renovation tasks effectively.

Q: How long does the battery last on a full charge?

Depending on the battery configuration (4.0Ah or 5.0Ah) and the intensity of use, a full charge typically allows 1.5 to 3 hours of continuous work on standard drilling or chipping tasks. The included chargers (2A or 4A) recharge batteries fully within 60–90 minutes.

Q: Does the brushless motor really make a difference?

Absolutely. Brushless motors run cooler, are more energy-efficient, and last longer than brushed motors. They also deliver consistent power output, which is critical for tough materials like concrete.

Q: Is it heavy to operate for long periods?

The tool is designed with ergonomics in mind, weighing approximately 3.2kg (with battery). The auxiliary handle and balanced design reduce user fatigue even during extended use.
