SNMU1706AN AH140 Milling Insert for Milling – Tungaloy

A SNMU1706AN AH140 insert designed for compatible Tungaloy milling systems, offering a sharp cutting edge and secure performance across face, shoulder, slot, high-feed and contour milling applications.

• PVD-coated carbide AH140 for wear resistance
• Sharp cutting edge for process security
• Square 17 mm form with 90° geometry
• Cylindrical hole with 40°–60° double countersink

Consistent milling performance through hardened carbide and coating

The SNMU1706AN AH140 is manufactured from carbide and finished with a PVD coating, which together deliver high abrasion resistance and a stable cutting edge. This combination reduces flank wear and helps maintain dimensional accuracy over longer tool lives. For production environments where cycle stability matters, the AH140 grade supports a balance between edge strength and wear resistance, making the insert suitable for demanding, repetitive milling tasks while reducing unplanned tool changes.

Secure seating and predictable chip control for efficient machining

Designed for inserts with a matching seat and geometry in the milling body, the square form and cylindrical hole with double-sided countersink (40°–60°) ensure secure clamping and axial positioning. The double-sided chipbreaker promotes consistent chip formation and evacuation, lowering the risk of built-up edge and workpiece damage. Together, these features contribute to shorter setup times and more reliable throughput in batch or continuous milling operations.

Optimised for process reliability and sharp-edge performance

The zero corner radius and sharp cutting edge of this insert provide clean entry and exit during shoulder and contour passes, improving surface finish and reducing burr formation. The 90° cutting angle supports robust cutting forces for face and slot milling, while the 6.35 mm plate thickness gives stable support under higher feeds. Such design choices aim to reduce vibration and support repeatable part quality, important when consistency and first-pass yield are priorities.

Versatile application range with clear integration requirements

This insert suits a wide range of milling tasks—face, shoulder, slot, high-feed and contour milling—provided that the insert seat, geometry and cutter body are technically compatible with the system. The insert’s specifications, including square 17 mm form, 6.35 mm thickness and the SNMU1706AN ISO designation, should be verified against the chosen milling body to ensure correct fit and clamping. Where a sharp cutting edge combined with process security is required, this AH140 grade offers a dependable solution without sacrificing robustness.
