DCMT 11T308 AH120 turning insert by Tungaloy — PVD-coated carbide, 0.8 mm corner radius

A DCMT11T308 AH120 indexable turning insert designed for ISO‑standard holders, intended for external and internal turning applications where a sharp cutting edge and high process security are required.

• PVD-coated carbide for wear resistance
• Sharp cutting edge for process security
• Rhombic form with 55° included angle
• Cylindrical hole with countersink 40°–60°

High repeatability for reliable production cycles

The PVD-coated carbide grade AH120 delivers consistent edge stability and reduced flank wear, which supports longer tool life and predictable part quality. For series production, these properties translate into fewer tool changes and less unplanned downtime. The geometry with a 0.8 mm radius balances cutting-edge strength and surface finish, making the insert suitable for medium to fine finishing cuts while maintaining robust performance under varying cutting conditions.

Geometry and holder compatibility explained for quick selection

The rhombic shape with a 55° included angle conforms to ISO turning formats and is compatible with ISO toolholders that match the form, relief angle, tolerance class, fastening style, size and thickness. The insert’s cylindrical hole with a single-sided countersink (40°–60°) enables secure clamping and repeatable positioning in standard clamping systems. When choosing a holder, ensure matching pocket geometry and screw type to achieve optimal seat contact and stable cutting behaviour.

Chip control and application suitability for turning tasks

This cutting grade is produced with a single-sided chipbreaker adapted to common turning operations; it manages chip formation effectively for many steels and alloyed materials. The combination of grade and cutter geometry supports stable cutting at moderate feeds and cutting depths, reducing vibration and improving surface integrity. For users less familiar with insert grades: a chipbreaker shapes the chip to prevent long, entangling swarf and to protect the cutting edge during continuous cuts.

FAQ

What materials is this insert suitable for?
The AH120 grade and carbide substrate are intended for a wide range of turning tasks; the Tungaloy DCMT11T308 AH120 insert performs well on many steels and alloyed materials when cutting parameters are chosen to match component stability and machine capability.

How is compatibility with a toolholder ensured?
Compatibility depends on matching the insert form, relief angle, tolerance class, fastening method, size and thickness; the rhombic DCMT geometry and ISO numbering make it straightforward to compare with ISO‑compliant holders.

What is the purpose of the countersunk hole design?
The cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and repeatable seating in standard clamping systems, helping to maintain consistent cutting conditions and tool life.

Can this insert be used for finishing and light roughing?
Yes — the combination of a 0.8 mm corner radius and the sharp cutting edge in grade AH120 makes the insert suitable for both finishing and light roughing, provided cutting speeds and feeds are adjusted according to the workpiece material and machine rigidity.
