This buying guide covers solid tungsten carbide rods, tolerance grades, grinding & coolant hole processing. Ideal for cutting tool blanks, punches and precision wear part manufacturers.
Full Article Structure
1. What Are Solid Tungsten Carbide Rods
Solid tungsten carbide rods are sintered cylindrical cemented carbide blanks. They are widely used as raw blanks for cutting tools, punches, forming pins and wear-resistant parts. High hardness and good bending strength make them the preferred blank for secondary machining.
2. Main Tolerance Classes for Carbide Rods
| Tolerance Grade | Diameter Tolerance | Main Usage |
|---|---|---|
| Normal Sintered Rod | ±0.03~±0.05 mm | Secondary grinding, rough processing |
| Ground Rod | ±0.01~±0.02 mm | Drill bits, end mill blanks |
| High Precision Ground Rod | ±0.005 mm | Precision punches, positioning pins |
3. Common Machining Options
- Plain sintered rod: Low cost, for customers who finish grinding in-house
- Center hole rod: With pre-drilled coolant holes for cutting tools
- Single / double hole carbide rod: Internal coolant channel for deep hole machining
- Custom length cutting: Cut-to-length service to match your production
4. Typical Application Scenarios
- Cutting tool industry: End mill, drill, reamer blanks
- Mold & stamping: Punches, core pins
- Mechanical automation: Wear pins, guide shafts
- Knife & scissors industry: Small forming tool blanks
5. FAQ for Carbide Rod Bulk Purchase
Q1: Can you cut carbide rods into custom lengths?
Yes, we provide cutting, grinding and hole processing service based on your requirements.
Q2: What is the standard length of carbide rods?
Common standard length is 330mm, custom lengths are acceptable for bulk orders.
6. Summary
Choose sintered or ground carbide rods based on your internal machining capacity and tolerance requirement. Pre-machined rods save your workshop cost. Send your diameter, tolerance and length requirement for quotation.
