APMT 070308 GH330 — Indexable milling insert for milling, Tungaloy

APMT070308 GH330 is an indexable milling insert designed for face, shoulder, slot, high-feed and contour milling where matching insert seat and geometry is required

• GH330 grade for long wear resistance
• Parallelogram form for stable seating
• 0.8 mm corner radius for edge stability
• Cylindrical hole with 40°–60° countersink

Productivity through balanced material properties

The GH330 grade is engineered as a carbide solution that balances wear resistance, toughness and edge stability, making it suitable for a wide range of milling tasks. Because the cutting material combines hardness with controlled toughness, the insert maintains cutting-edge integrity under intermittent loads; this leads to more consistent component quality and fewer insert changes. The design supports productive machining strategies such as face and shoulder milling while helping to reduce unscheduled downtime.

Secure clamping and geometry for reliable machining

The parallelogram plate form and the cylindrical hole with one-sided countersink (40°–60°) provide mechanical stability in the toolholder and promote accurate seating of the insert. The combination of seating geometry and the specified 3.18 mm plate thickness reduces micro-movements that can cause premature edge wear. The 85° approach geometry complements medium- to heavy-duty milling passes and supports consistent chip evacuation when paired with the one-sided chipbreaker, improving surface finish and process reliability.

Application scope and handling advantages

Intended specifically for milling, the insert is compatible with Tungaloy tool families when insert seat, geometry and clamping match. Typical uses include planing, shoulder work, slotting, high-feed and contour tasks depending on the chosen cutter body. The 0.8 mm corner radius helps to protect the cutting edge during interrupted cuts and when engaging variable cross-sections, providing a compromise between edge strength and the ability to produce sharp contours. Handling is straightforward: identify the matching cutter body and fastening hardware, align the insert in the seat and clamp securely using the specified screw and seating components.

FAQ

What machining tasks is this insert intended for?
The APMT070308 GH330 indexable milling insert (Tungaloy, article 6800927) is intended for face, shoulder, slot, high-feed and contour milling when used in a compatible Tungaloy milling system.

How does the GH330 grade affect tool life?
GH330 provides a balance of wear resistance and toughness; in practice the GH330 grade extends edge life under mixed cutting conditions by improving resistance to flank wear while preserving edge stability.

Which holder geometry is required for secure use?
A matching Tungaloy milling body with a parallelogram seat that corresponds to the insert geometry and an appropriate clamping screw is required; the cylindrical hole with countersink secures the plate and prevents rotation.

Can this insert be used for interrupted cuts?
Yes. The 0.8 mm corner radius increases edge strength during interrupted cuts and when traversing variable section thicknesses, reducing the risk of chipping.

What chip control can be expected?
The one-sided chipbreaker is designed for efficient chip formation in typical milling feeds and contributes to improved surface quality and evacuation when paired with the correct cutter body.
