### **Cons of the Makita 8400DW**

1. **Expensive Upfront Cost**

- The **8400DW itself is priced higher** than many cordless hammer drills, especially when paired with a high-capacity battery.

- Additional **batteries and accessories** (e.g., XCV186H) can add significant cost, making it a larger investment than entry-level tools.

3. **SDS-Plus Chuck Limitations**

- The **3/8" SDS-Plus chuck** is great for masonry but **not as versatile** as a standard 1/2" SDS-Plus or 3/8" SDS-top chuck.

- Some users may find it **less flexible** for general drilling tasks compared to tools with a 1/2" chuck.

4. **Battery Compatibility Issues**

- **Not compatible with all 18V Makita batteries** (e.g., older XCV182 or non-LXT batteries may not fit or perform optimally).

- Requires **Makita s newer battery platforms** (LXT or XCR), which can be an additional cost if upgrading from older tools.

5. **Weight for Some Users**

- While **6.9 lbs is lightweight for an 18V hammer drill**, some users (especially those with smaller hands or wrist issues) may find it **heavier than expected** during prolonged use.

- Some users report **hand fatigue** after heavy use, though this varies by individual.

7. **Maintenance Requirements**

- While durable, **regular cleaning is needed** to prevent dust and debris from affecting performance.

- **SDS-Plus bits may wear out faster** in masonry work compared to standard drill bits.
