The “Zero-Upgrade” Radius Solution
Stop swapping milling heads. Stop spending hundreds of dollars on specialized radius guide rollers and heads. RAYKAR’s innovative Direct-Fit R3 Inserts are designed to drop straight into your standard 45° beveling head slot.
Whether you are preparing steel plates for PSPC (Performance Standard for Protective Coatings) compliance in shipyards or ensuring safety edges on bridge structures, these inserts deliver a perfect 3mm radius (R3) with zero machine modification.
• ❌ No need to buy an expensive Radius Milling Head (Save $400+).
• ✅ PSPC Compliant: Perfect for shipbuilding and steel structure edge rounding (R3).
• ✅ Premium Kit: Includes 10 inserts + 10 high-strength Torx screws.
Why Choose RAYKAR R3 Inserts?
