Milling cutter bodies accept ceramic button inserts for machining at high speeds

Walter has introduced the M2472 and M2473 milling cutters with ceramic button indexable inserts. The M2472 cutter body accepts positive ceramic inserts, and the M2473 cutter body accepts double-sided ceramic inserts with eight or more cutting edges per indexable insert. The cutting diameters range from 32 to 63 mm.

The grades of the ceramic inserts are based on the elements silicon, aluminum, oxygen, and nitrogen (SiAlON). The WIS10 SiAlON grade is designed for very stable conditions and offers wear resistance. The WIS30 SiAlON grade is targeted for universal applications due to its extreme toughness.

The inserts can be used without cooling lubricant, where compressed air or minimum quantity lubrication (MQL) is applied for beneficial results.

The milling cutters bodies are suited for roughing heat-resistant super alloys (ISO S workpiece group), such as Inconel, Incoloy, Monel, Nimonic, Haynes, Stellite, Udimet, Wapaloy, and Hastelloy alloys.
