TNMU 1207R1 AH120 — Milling insert (milling) by Tungaloy, PVD-coated carbide, 60°

The TNMU1207R1 AH120 is an indexable, PVD-coated carbide insert engineered for use in Tungaloy milling systems; it is intended for face, shoulder, slot, high-feed and contour milling where a sharp cutting edge and process security are required.

• PVD-coated wear- and chip-resistant AH120
• Triangular 60° form for versatile milling
• Double-sided chipbreaker for process security
• Cylindrical hole with double countersink 40°–60°

Consistent cutting performance through advanced coating and grade

The PVD-coated AH120 carbide composition provides a balance of wear resistance and edge toughness that suits a wide range of milling tasks. The physical vapour deposition layer reduces flank and crater wear while the substrate retains fracture resistance under interrupted cuts. This combination supports longer tool life and more consistent cycle times, which translates into improved operational efficiency and predictable part quality in production environments where stability and sharp edges matter.

Geometry designed for adaptable process control and chip management

A triangular 60° plate form with a double-sided chipbreaker offers two effective cutting edges per face and reliable chip control during varying depths of cut. The insert’s 0 mm corner radius and 7.94 mm plate thickness give a robust edge for shoulder and slot milling, while the double-sided chipbreaker helps maintain surface finish and evacuation of swarf. The design therefore reduces the risk of edge chipping and supports stable machining across materials typically processed in milling operations.

Practical system integration for reliable clamping and quick changeover

The insert features a cylindrical hole with double countersink (40°–60°) to suit secure clamping with standard Tungaloy cutter bodies; correct seat geometry and clamping screw selection ensure repeatable positioning and torque transmission. As part of a matched milling system, this indexable solution lowers setup time and simplifies inventory management, delivering reproducible results across batches. The documented specification allows straightforward selection for shops aiming to increase uptime and maintain consistent surface quality.

FAQ

What materials is this insert suited to machine? The TNMU1207R1 AH120 insert is formulated for a broad range of machining tasks and performs well where a durable, fracture-resistant edge is required; the PVD-coated carbide grade supports process security across many steels and common alloys.

Is the insert reversible or single-sided? This is a double-sided, triangular indexable insert; the double-sided chipbreaker and triangular form enable multiple effective cutting edges before replacement.

What does the AH120 grade provide compared with other grades? AH120 delivers a wear- and chip-resistant performance profile, combining a hard PVD coating with a tough carbide substrate for improved edge life and reduced risk of breakouts during milling.

How is the insert clamped in the cutter body? The TNMU1207R1 uses a cylindrical centre hole with a double countersink (40°–60°) to secure it with a clamping screw in compatible Tungaloy milling bodies; correct seat geometry is essential for reliable clamping.

Can this insert be used for high-feed milling? Yes, the insert’s geometry and AH120 grade make it suitable for high-feed applications within the limits defined by the associated cutter family and machine capability.
