New specialists for the standard programme

2 May 2025

Walter is enhancing its expertise in the machining of non-ferrous metals with its new range of PCD milling cutters. As most PCD tools are often customised solutions, Walter is also expanding its standard ISO N range with the solid MP271 and MP470 milling cutters.

The three-edged MP271 drill slot cutter, available in 16 to 25mm diameter, features a segmented cutting edge length of 30mm and a centre cutting edge, making it ideal for deep depths of cut. This makes the MP271 the ideal choice for operations such as trimming, as its differential pitch geometry minimises vibration.

Complementing the MP271 is the double-edged MP470 spherical cutter, available in diameters of 4, 6, 8, 10, 12 and 16mm. This two-flute ball-nosed end mill is designed for creating and finishing free-form surfaces. Depending upon the diameter selected, the MP470 ball-nosed end mill has a cutting length from 4 to 14mm with an overall length of 55 to 80mm.
Both PCD milling cutters have been specifically developed for ISO N materials such as aluminium, Al-Si alloys, magnesium alloys, copper alloys and fibre composites. Utilising Walter's WDN20 PCD grade, the new arrivals can significantly extend the tool life and machining performance.
The brazed PCD cutting edges are also suitable for reconditioning.

Combining this opportunity to recondition with the substantial extension of tool life significantly enhances the tools' sustainability. Furthermore, this reduces the costs of cutting tools to further increase the cost-effectiveness. The specific properties make these exciting new PCD milling cutters particularly appealing for manufacturers machining aluminium in general mechanical engineering as well as in the automotive and aviation industries.
