VCMT160408-PS AH725 – ISO rhombic turning insert, PVD-coated carbide by Tungaloy

VCMT160408-PS AH725 is a rhombic ISO turning insert for external and internal turning, featuring a PS chipbreaker and a cylindrical hole with single-sided countersink for secure clamping

• PVD-coated AH725 grade for reliable performance
• Universal use on steel and stainless steels
• ISO rhombic VCMT form with 0.8 mm radius
• Cylindrical hole with single-sided countersink

Optimised cutting performance across varied materials

The insert combines a PVD-coated surface with the AH725 carbide grade to deliver stable, predictable wear behaviour across mixed batches of steel and stainless steels. The PVD layer increases hardness at the cutting edge and reduces built-up edge formation, which translates into longer periods between index changes and lower total machining costs. Because the grade is designed to be breakout-resistant, it is particularly suitable for smaller tools and applications where high process reliability is required; the result is fewer interruptions and more consistent production output.

ISO compatibility and secure clamping for faster tool changeovers

The geometry follows ISO conventions so compatibility with holders is determined by form, clearance angle, tolerance class, fixation, size and thickness. The rhombic VCMT shape gives a 35° included angle together with a 7° clearance that matches standard tool seats; the insert measures 16 mm across the flats with a plate thickness of 4.76 mm. The centre has a cylindrical hole with a single-sided countersink (40°–60°) to ensure firm screw seating and repeatable clamping. Using an appropriate external holder or boring bar with the matching clamp set and replacement screws completes the system and simplifies inventory management for workshops.

Practical machining advice for reliability and efficiency

Chip control is provided by the chipbreaker PS, which supports consistent chip shape in general turning operations and eases chip handling. The modest 0.8 mm corner radius balances strength and surface finish, making the insert suitable for fine turning and light interrupted cuts where dimensional accuracy and surface quality are priorities. For unstable setups or long overhangs a reduced feed or a stiffer holder is recommended to maintain process stability. Selecting the correct chipbreaker and matching cutting parameters to material and rigidity will reduce tool wear and improve cycle times.

FAQ

What materials is this insert suitable for?
The VCMT160408-PS AH725 from Tungaloy is designed primarily for steel and stainless steels, offering a universal, breakout-resistant grade suitable for mixed-material batches.

How is the insert clamped and what is the hole style?
Clamping uses the central cylindrical hole with a single-sided countersink (40°–60°) to ensure secure seating; select a matching clamp set and screw for repeatable clamping.

What does the chipbreaker PS mean for machining?
The PS chipbreaker provides controlled chip formation for general turning tasks, improving chip evacuation and contributing to stable, predictable cutting in medium-duty operations.

Which dimensions determine holder compatibility?
Holder compatibility is governed by the insert form (VCMT), the 35° included angle, the 7° clearance, plate size 16 mm and thickness 4.76 mm—these factors must match the chosen toolholder.

What applications suit a 0.8 mm corner radius?
A 0.8 mm corner radius is well suited to fine turning and light interrupted cuts where a balance between edge strength and surface finish is required; it supports dimensional accuracy with moderate cutting forces.
