Are corded drills more powerful?

In corded drills, the sustained power during continuous operation is generally greater than that of cordless drills. Below is a detailed explanation of this conclusion:

Energy Supply Stability

Corded Drills: Powered directly by an AC power source, they provide stable and continuous energy output. This ensures consistent power delivery during operation, maintaining strong performance over time.
Cordless Drills: Rely on built-in batteries. While a fully charged battery can deliver sufficient power initially, its capacity diminishes with prolonged use, leading to reduced performance. Especially during extended operation, cordless drills may struggle to match the sustained power of corded models.

Power and Performance

When comparing drills of the same power rating, corded and cordless models may perform similarly in short bursts. However, due to battery limitations, cordless drills often cannot maintain consistent power output during prolonged use.

Application Scenarios

Corded Drills: Better suited for long-duration, high-intensity tasks, such as construction sites or large-scale renovation projects.
Cordless Drills: More ideal for small-scale renovations, home DIY projects, and situations requiring flexibility and portability. In these cases, the demand for sustained power and stability is relatively lower.

Core Comparison: Key Differences Between Corded and Cordless Drills

1. Power and Performance

Corded Drills: Typically offer higher power (commonly 500W–800W), making them suitable for prolonged drilling or working with hard materials (e.g., concrete, metal). For example, the Bosch GSB 500 RE (corded) delivers up to 50N·m of torque (source: Bosch official website).
Cordless Drills: Depend on battery power, with mainstream voltages ranging from 12V–20V and torque mostly below 30N·m. High-end models like the Xiaomi Brushless Drill (20V) provide about 2 hours of runtime (real-world testing), but continuous high-load usage significantly reduces battery life.

2. Portability and Usage Scenarios

Cordless Advantage: No need for a power outlet, making them ideal for outdoor work, elevated spaces, or confined areas (e.g., installing curtains or assembling furniture).
Corded Advantage: More stable performance but limited by power cords. Best suited for fixed workspaces like garages or workshops where intensive tasks are performed.

Purchasing Guide: Matching Drill Type to Needs

1. Budget and Maintenance Costs

Corded Drills: Lower upfront cost (¥200–500), no battery replacements needed.
Cordless Drills: Higher initial price (¥300–1000), with additional batteries costing ¥200–400 each. Long-term use requires considering battery lifespan (3–5 years for lithium batteries).

2. Special Considerations

Versatility: If multi-functionality is needed, opt for a cordless combo kit (e.g., DeWalt DCD796D2, 20V, compatible with screwdriving and drilling modes).
Noise Levels: Corded drills are generally quieter (<75 dB), while cordless models may exceed 80 dB (per EU tool noise standards).

Conclusion

While cordless drills are becoming the trend, corded models remain irreplaceable for heavy-duty tasks.

Home users: Prioritize cordless drills (12V–18V for best cost-performance ratio).
Professional/heavy users: Keep a high-power corded drill as a backup.

Configuration of cordless Drill and pacakges:

Normally configuration also can customized according to customer requirement, such as Unit price(2pcs battery,1pc charger, BMC pack with accessories ); Unit price(Color box pack, 1pc battery,1pc charger without accessories); Unit price(only BMC pack without accessories, 2pcs battery, 1pc charger). Package all can customize.
