Case Study: Real Business, Real Results
Based in Austin, Texas, Electronix Fabricators sought an upgrade for tackling tough glass-reinforced circuit boards more efficiently.
“Switching to the 7-PR Diamond Cut Router drastically improved our routing precision and reduced material waste by nearly half. The down-cut action means less edge chipping, which really saves us time in cleanup.”
Maria Gonzalez – Production Manager
Output increased by 35% and rework rate cut in half
Why Diamond Cut Style A with No End-Cut Makes Your Routing Cleaner
This style ensures that the cutting edges don’t contact the material ends, which prevents tearing and rough edges while routing. Think of it like using a birthday candle on a cake—the flame only touches the top, keeping the sides neat. This feature avoids damaging delicate materials, especially brittle composites like glass-reinforced PCBs, giving you smoother finishes and less sanding down after the job.
Installation and Maintenance Guide
Setting It Up
- Securely insert the 1/2 inch shank into your router collet.
- Ensure the collet nut is tightened firmly to avoid wobbling.
- Set your router speed according to material hardness—slower for highly abrasive composites.
- Always wear safety goggles and a dust mask before starting.
- Test cut on scrap material to verify setup before working on your piece.
Keeping It Going
- Clean the burr after every use to remove resin and residue buildup.
- Use a soft brass brush or ultrasonic cleaner for thorough cleaning.
- Store in a dry, dust-free area to prevent rust or corrosion.
- Avoid drastic speed changes to prolong burr life.
- Inspect regularly for dullness and replace when cutting performance declines.
Frequently Asked Questions
Q: What materials is the 7-PR burr best suited for?
The 7-PR is designed for routing abrasive materials like glass-reinforced PCBs and phenolic-epoxy composites.
Q: Can I use this burr on metals?
While possible, this burr is optimized for abrasive composites and may wear quickly on metals.
Q: What does 'no end-cut' mean?
'No end-cut' means the burr doesn’t cut on its tip, preventing damage to the surface edges.
Q: How do I choose between standard and double cut?
Standard cut is for general use; double cut gives smoother finishes especially on harder materials.
Q: What speed should I run my router at?
Start with slower speeds for abrasive materials and adjust as needed for clean cutting without overheating.
Q: How long is the cutting length?
The cutting length is 1 inch, offering precise control over routed sections.
Q: Is this burr compatible with all routers?
It fits routers with a 1/2 inch collet size, which is common in professional tools.
