Full Article Structure
1. What Is h6 Tolerance for Carbide Rods
h6 is a standard precision shaft tolerance widely used for solid carbide tool blanks. For small diameter carbide rods, h6 guarantees tight diameter deviation, making it suitable for end mill, drill and reamer blank production.
2. Difference: Sintered Blank vs Fine Ground Rod
| Item | Sintered Carbide Blank | h6 Fine Ground Rod |
|---|---|---|
| Diameter Tolerance | ±0.03~0.08 mm | h6 standard tight tolerance |
| Surface | As-sintered matte surface | Mirror fine ground finish |
| Typical Usage | Secondary grinding by buyer | Direct clamping for tool making |
3. Core Check Items Before Purchase
- Confirm diameter tolerance class: h6, h7 or custom tighter tolerance
- Check straightness: straightness error causes uneven grinding and tool runout
- Surface finish: scratch-free ground surface reduces wheel wear during regrinding
- Length tolerance and end face condition: square cut ends or chamfered ends
4. Common Buying Mistakes to Avoid
- Mistake 1: Treat sintered blank as h6 ground rod, leads to high rework cost
- Mistake 2: Ignore straightness, only focus on diameter size
- Mistake 3: No tolerance certificate provided with bulk shipment
