WALTER Diamond Turning Insert: DNMG442-FM5 WMP20S

The WALTER DNMG442-FM5 WMP20S (also DNMG150608-FM5 WMP20S) is a diamond indexable turning insert used for precision machining of non-ferrous materials, composites, and abrasive alloys. It is commonly applied in automotive, aerospace, and general engineering for finishing and semi-finishing operations where tight tolerances and surface quality are required.

The WALTER diamond turning insert MPN 7091917 is available in two specification variants: DNMG442-FM5 WMP20S and DNMG150608-FM5 WMP20S. Both are indexable inserts with a diamond grade designed for wear resistance. The DNMG150608 designation indicates a 15 mm inscribed circle, 6 mm thickness, and 0.8 mm nose radius.

To select the correct WALTER diamond turning insert, match the insert geometry (e.g., DNMG150608) to your tool holder's pocket size and clamping system. Consider the workpiece material—diamond inserts suit non-ferrous and abrasive materials. The FM5 chipbreaker and WMP20S grade indicate a positive rake geometry for finishing cuts.
