Why Deburring is Essential:

• Prevents Leaks – Burrs can prevent proper sealing in flared connections
• Protects O-Rings – Sharp edges can damage O-rings and seals
• Improves Flow – Smooth edges reduce turbulence and pressure drop
• Professional Finish – Clean, deburred tubes indicate quality workmanship
• Prevents Contamination – Burrs can break off and contaminate the system

How to Use:

Inside Deburring:

1. Insert pointed reamer end into tube
2. Rotate clockwise whilst applying light pressure
3. Continue until burrs are removed
4. Remove reamer and check inside edge

Outside Deburring:

1. Place tube in V-shaped groove on reamer
2. Rotate reamer around outside of tube
3. Continue until burrs are removed
4. Check outside edge for smoothness

Maintenance:

• Keep blade sharp for best results
• Replace blade when dull or damaged
• Clean reamer after each use
• Store in dry location to prevent rust
• Inspect regularly for wear
