Carbide Turning Insert PLYTKA SNMG 120408 STE FM15I — Pafana

PLYTKA SNMG 120408 STE FM15I is a Pafana carbide turning insert in SNMG 120408 geometry designed for general external and internal turning. The insert features indexable cutting edges that allow quick rotation to a fresh edge, reducing downtime and providing consistent cutting performance across a range of materials. The FM15I grade balances wear resistance and toughness to suit typical turning operations in steel and similar alloys when appropriate cutting parameters are used.

Advantages

The SNMG 120408 shape provides four usable cutting edges per insert, enabling efficient edge changes without regrinding. Carbide construction offers stable heat resistance and dimensional stability at elevated cutting temperatures. The FM15I grade combines abrasion resistance with toughness to reduce chipping and extend tool life in interrupted cuts and continuous turning. The indexable format simplifies inventory management and reduces per-edge cost compared with brazed or solid carbide tools.

Suitable for

• External turning of shafts and cylindrical parts
• Internal boring and light internal turning where SNMG geometry fits the holder
• General-purpose machining of steels and similar materials depending on grade recommendations
• Operations requiring quick edge indexing to reduce setup time

Key specifications

• Geometry: SNMG 120408 indexable insert shape
• Grade: FM15I—carbide formulation balancing wear resistance and toughness
• Number of cutting edges: four indexable edges per insert
• Application type: external and internal turning
• Material: cemented carbide suitable for typical turning workloads

How to use

Fit the SNMG 120408 insert into a compatible SNMG-style tool holder and tighten the clamping mechanism according to the holder manufacturer's torque recommendations. Select cutting speeds, feeds, and depths of cut appropriate for the work material and the FM15I grade—start with conservative parameters and adjust based on surface finish and tool wear. Rotate the insert to a fresh cutting edge when wear or chipping is observed. Ensure proper coolant or lubrication is used if required for the workpiece material and machining conditions.

Usage recommendations

For best results, verify holder compatibility with SNMG 120408 inserts and follow Pafana or tooling supplier guidelines for cutting data with FM15I grade. Use steady clamping, maintain correct tool overhang, and monitor insert condition regularly to optimize life and part quality.
