## Common ground
Both options are types of hammering machines used to shape or form materials, typically through impact.
## Options at a glance
**8462.19 – Working metals**
- **Defining trait:** Designed specifically for industrial metalworking (e.g., forging, shaping).
- **Typical examples:** Hydraulic presses, drop hammers in steel mills.
- **Best fit when:** Used in factories to process large metal parts or components.
**8467.29 – Handheld with electric motor**
- **Defining trait:** Portable, manually operated with an integrated electric motor; intended for personal or on-site use.
- **Typical examples:** Electric nail guns, handheld impact drivers, power hammers for small repairs.
- **Best fit when:** Used by individuals or in construction/repair tasks requiring mobility and ease of handling.
## Key differences
| Feature | 8462.19 (Metalworking) | 8467.29 (Handheld Electric) |
|-----------------------|------------------------|------------------------------|
| Power source | Industrial (e.g., hydraulic, electric grid) | Self-contained electric motor |
| Portability | Fixed or large-scale setup | Portable, handheld |
| Primary use case | Factory/industrial metal shaping | On-site, personal repair tasks |
## How to choose
- Is the machine used in a factory for large-scale metal forming? → 8462.19
- Is it handheld and powered by its own electric motor for personal or mobile use? → 8467.29
## Overlaps & pitfalls
A machine could technically be both (e.g., a small electric hammer used in metalwork), but the **main function** determines the classification. If it’s primarily for industrial metal shaping, use 8462.19; if it's designed for portability and personal use, even with metal applications, use 8467.29. The key is whether it's built for fixed industrial use or mobile, hand-held operation
