Cutting Insert PLYTKA APKT 1604 PDTR FU25N — Pafana (APKT 1604, index FU25N)

PLYTKA APKT 1604 PDTR FU25N from Pafana is a turning cutting insert intended for precision metalworking. The APKT 1604 designation refers to the insert's triangular geometry and nominal size, while the FU25N marking identifies the specific grade and geometry variant suitable for finishing and light turning tasks. The insert is designed to be mounted in compatible toolholders and used for external and light finishing operations on a variety of metals.

Advantages

The APKT 1604 PDTR FU25N insert delivers consistent cutting edge stability and repeatable geometry for controlled chip formation and surface finish. Its grade and geometry combination provide good wear resistance during finishing passes and help maintain dimensional accuracy. The triangular shape allows for multiple cutting edges per insert, increasing usability and reducing changeover frequency.

Suitable for

• External turning and light finishing of steel and non-ferrous metals
• Precision profile turning where consistent surface quality is required
• Applications on compatible toolholders requiring APKT 1604 insert geometry
• Short to medium production runs with frequent edge indexing

Key specifications

• Insert geometry: triangular APKT 1604 form suitable for turning
• Grade/variant: FU25N geometry/grade optimized for finishing
• Typical use: external turning, finishing passes
• Cutting edge: multiple indexed edges per insert for reuse
• Compatibility: designed for standard toolholders that accept APKT 1604 inserts

How to use

Install the APKT 1604 PDTR FU25N insert into a compatible toolholder following the toolholder manufacturer's clamping and torque recommendations. Use appropriate cutting parameters for finishing operations: moderate depth of cut, light feed rates and cutting speeds matched to the workpiece material and the FU25N grade. Verify correct seat and orientation to ensure stable engagement of the cutting edge and secure clamping to avoid vibration and edge damage.

Usage recommendations

For best results, select cutting speeds and feeds according to the workpiece material—lower speeds for hardened steels, higher speeds for non-ferrous metals—and favor shallow depth of cut for finish passes. Monitor insert wear and index or replace inserts when edge rounding or chipping affects surface quality or dimensional accuracy.
