APMT 09T308 AH140 indexable insert for milling — Tungaloy

APMT09T308 AH140 Tungaloy-Wendeplatte is an indexable carbide insert designed for a wide range of milling tasks, offering reliable cutting performance in Tungaloy milling systems.

• PVD-coated carbide for wear resistance
• Sharp cutting edge for process security
• Parallelogram shape for versatile milling
• Cylindrical hole with countersink for secure clamping

High wear resistance that sustains production

The PVD-coated carbide grade AH140 is formulated to combine wear and chipping resistance, delivering consistent machining performance under varying cutting conditions. The result is improved tool life and fewer interruptions in the production flow, which supports predictable cycle times and reduces unscheduled tool changes. This behaviour is particularly beneficial in serial production where steady output and component quality are priorities.

Secure fit and robust clamping for stability

Designed with a parallelogram shape and a cylindrical hole with a one-sided countersink, the insert ensures positive seating and repeatable alignment in compatible milling bodies. The 85° wedge angle and the specified relief geometry help maintain cutting stability, reducing vibration and promoting a stable cutting edge during shoulder and contour milling. This mechanical compatibility reduces the risk of insert movement and supports consistent surface finish.

Practical geometry for diverse milling tasks

A single-sided chipbreaker and the specified geometry make the insert suitable for plan, shoulder, groove, high-feed and contour milling depending on the chosen cutter body. The 3.97 mm thickness combined with a 0.8 mm corner radius helps balance edge strength and dimensional control, allowing the insert to handle interrupted cuts and variable engagement angles while preserving edge integrity and workpiece tolerances.

Clear material and application guidance

Manufactured from sintered carbide and delivered as a PVD-coated grade, this indexable insert is intended specifically for milling systems where plate seat, geometry and cutter body match are required. The single-sided chip control aids chip flow in many common materials processed in milling, while the insert’s overall design supports efficient, repeatable results in production environments that prioritise process reliability.

FAQ

What materials is this insert suitable for?
The APMT09T308 AH140 Tungaloy insert is a PVD-coated carbide grade engineered for general milling; it offers wear and chipping resistance across common materials encountered in milling operations.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius provides a balance between edge strength and achievable surface finish, helping to withstand intermittent cuts while maintaining dimensional control.

Does the insert require a specific cutter body?
The insert must be used in milling bodies that match the plate seat and geometry; the parallelogram shape and hole/countersink design require a compatible Tungaloy-style cutter body for correct seating.

What is the purpose of the one-sided chipbreaker?
The single-sided chipbreaker directs chip flow for the intended cutting direction, improving chip control and reducing the risk of chip-related surface defects in typical milling operations.

Is the coating suitable for high-speed milling?
The PVD coating enhances wear resistance and is appropriate for many milling speeds; final cutting parameters should be set according to the workpiece material and machine capabilities.
