CNC Six-Sided Drill vs Five-Sided Drill: Which One Should You Choose?
Detailed comparison of CNC six-sided drills and five-sided drills for panel furniture production. Pros, cons, and when to choose each type.
The Core Difference
The difference is simple: a six-sided drill processes all six faces of a panel (including the bottom), while a five-sided drill processes only five faces (excluding the bottom). But this simple difference has significant implications for your production.
When You Need Six-Side Processing
Most panel furniture requires holes on the bottom face for:
- Shelf support pins
- Cam lock connections
- Dowel joints
- Hardware mounting
If your products need bottom-face drilling, a five-sided drill means you’ll need a secondary operation — adding time, labor, and potential for alignment errors.
Comparison Table
| Feature | Six-Sided Drill | Five-Sided Drill |
|---|---|---|
| Faces processed | 6 (all) | 5 (no bottom) |
| Bottom face drilling | Yes | No (secondary needed) |
| Cycle time | Single pass | 1-2 passes |
| Accuracy | ±0.1mm | ±0.1mm |
| Price range | Higher | Lower |
| Best for | Full panel processing | Top/edge-only work |
Cost Analysis
While a six-sided drill costs more upfront, consider the total cost:
Six-sided drill: Higher machine cost, but one operation Five-sided drill + secondary drill: Lower machine cost + second machine + extra labor + more floor space
In most cases, the six-sided drill wins on total cost of ownership within 12-18 months.
Recommendation
- Choose six-sided if you process cabinet boxes, wardrobes, or any product needing bottom-face holes
- Choose five-sided if you only need top and edge processing (e.g., decorative panels, door components)
- Choose PTP center if you need both drilling AND milling on complex components
