RFEN 2004ZF GH330 RFEN Indexable Insert for Milling by Tungaloy — round 20 mm, 4.76 mm thick, no-hole design

RFEN2004ZF GH330 Tungaloy indexable insert for productive milling applications, designed for use in compatible Tungaloy cutter bodies and suited to face, shoulder, slot, high-feed and contour milling operations.

• Optimised for Tungaloy milling systems
• GH330 grade: wear-resistant and tough
• Round 20 mm form with 4.76 mm thickness
• 25° relief angle for stable cutting

Reliable milling performance through matched system design

The insert is part of a complete system consisting of the cutter body, the indexable insert and clamping screw, where correct seating and geometry alignment are essential for repeatable performance. The RFEN series is engineered so that the insert seat and geometry match Tungaloy milling bodies, reducing the risk of instability at the cutting edge. For production environments this means fewer interruptions, more predictable tool life and a consistent surface finish, which together feed directly into reduced setup times and improved process reliability.

Material grade and what it means in practice

Manufactured from cemented carbide, the GH330 grade balances wear resistance and toughness, making it suitable for a wide range of milling tasks. The GH330 composition complements the cutting geometry to provide stable chip formation and good resistance to edge chipping. For operators not specialised in materials science: wear resistance increases time between index changes, while toughness helps avoid sudden edge failure when interrupted cuts or variable material compositions occur. The net effect is a more productive cutting cycle and lower tooling consumption per workpiece.

Geometry and handling benefits on the shop floor

The insert’s round 20 mm form and 4.76 mm thickness deliver secure clamping and even load distribution across the edge, particularly in contour and shoulder milling. The 25° relief angle ensures a consistent cutting engagement and helps control cutting forces during high-feed passes. The absence of a hole simplifies the contact surface and suits specific clamp designs; correct matching of the seat is mandatory for safe use. Where higher removal rates are required, this combination supports stable cutting and predictable tool-change intervals.

Process advantages and recommended applications

Designed for face, shoulder, slot, high-feed and contour milling depending on the tool family, this insert provides versatility across common milling operations. The system-oriented approach favours manufacturers seeking reproducible results and reduced process variability. When matched with the appropriate Tungaloy cutter body, the insert offers reliable surface quality and stable tool life, which contributes to improved throughput and lower rework rates in serial production.

FAQ

What milling operations suit this insert best?
This indexable insert is intended for face, shoulder, slot, high-feed and contour milling when used in the designated Tungaloy cutter families.

How does the GH330 grade affect tool life?
The GH330 grade provides a compromise of wear resistance and toughness, extending usable life under mixed cutting conditions while maintaining edge stability.

Is a specific cutter body required?
Yes, the insert requires a Tungaloy-compatible cutter body with a matching seat and geometry to ensure correct clamping and safe operation.

What are the key dimensions to verify before fitting?
Check the round form with 20 mm diameter, 4.76 mm thickness and the 25° relief angle to confirm compatibility with the clamping system.
