CPMT 120408 AH8005 indexable insert for turning, parting and grooving — Tungaloy

The CPMT 120408 AH8005 is a rhombic indexable insert designed for stable turning, parting-off and grooving operations in demanding materials.

• PVD-coated carbide AH8005 for wear resistance
• Rhombic CPMT 12 size, 4.76 mm thickness
• 0.8 mm corner radius for edge strength
• Cylindrical hole + single-sided countersink 40°–60°

Consistent edge life for stable production

The combination of the AH8005 grade and PVD-coated surface provides improved wear resistance when machining heat-resistant alloys and other hard materials. This results in a more predictable tool life and fewer unexpected tool changes, which supports continuous production. The rhombic geometry with a 0.8 mm radius balances edge strength and cutting precision, making the insert suitable for both finishing and modest finishing passes without frequent interruptions.

Engineered for demanding materials and processes

Optimised for machining high-temperature alloys and hard workpieces, the insert’s PVD coating lowers flank and crater wear under elevated cutting temperatures. The model family design targets systemised parting-off and grooving tasks with defined chip control; the single-sided chipbreaker promotes predictable chip flow during stable cutting conditions. When paired with appropriate holders from the same system family, operators can achieve reproducible results across batch runs.

Practical geometry and secure fastening

The insert features a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping in standard holders, reducing the risk of movement under cut. The 12 mm size and 4.76 mm thickness offer compatibility with common CPMT holders within the TungCut system family. Clear identification on the insert and consistent seating geometry simplify tool changes on the shop floor, aiding maintenance routines and reducing setup time.

Improve process reliability and productivity

Adopting the TungCut system with this PVD-coated carbide insert can enhance process security by reducing variability and supporting higher productive uptime. The insert’s wear properties are intended to give operators consistent surface finish quality and repeatability across series production. For operations focused on throughput and repeatable results, this insert provides a practical balance of robustness and cutting performance.

FAQ

Which materials is this insert suitable for?
The CPMT 120408 AH8005 insert from Tungaloy is designed for heat-resistant alloys and hard materials and performs well in stable machining conditions.

How does the AH8005 grade affect tool life?
The AH8005 PVD-coated carbide grade reduces wear at elevated temperatures, which helps to extend the cutting edge life and sustain consistent performance.

Can the insert be used for both parting and grooving operations?
Yes; the TungCut system family and the rhombic CPMT 120408 geometry are intended for parting-off and grooving as well as general turning tasks.

What clamping features should the holder provide?
A holder compatible with CPMT inserts that secures the insert via the cylindrical hole and countersink (40°–60°) ensures rigid clamping and repeatable seating for reliable machining.
