Walter presents the latest ConeFit Milling cutters

13 October 2025

With the upgrade of the ConeFit milling cutters, Walter is presenting the latest version of the interchangeable head system. Now, seventeen milling cutter families have been merged into eight and provided with new ordering codes adapted to the current nomenclature.

For customers, this means significantly simplified order handling. At the same time, applications benefit from a technical upgrade thanks to the newly added coating with the highly wear-resistant WJ30TP grade from Walter. The universal TiAlN coating with a gold-colored ZrN top layer not only extends tool life, it also allows rapid wear detection. Like all ConeFit replaceable heads, the enhanced milling cutters are also characterised by their high-precision and self-centring interface that consists of a thread, cone and contact surface. This enables tool changes with maximum speed, precision and stability.

As a particular technical highlight, the MD340 ConeFit Milling cutter is a specialist for ISO P materials. Its variable 39°/41° helix reduces vibration, which significantly increases operational smoothness, performance, surface finishes and tool life. The z4 milling cutter is available in a diameter range from 10 to 20mm, with and without a corner radius.

In addition to the current highlights, the MC430 and MC500 both also incorporate the WJ30TP grade. Additionally, the internally cooled MD070 has also been WJ30RA coated. This revised Walter ConeFit program also includes other milling cutters upgrades.

The wide selection of high-performance, re-grindable milling heads is complemented by their great flexibility. The range enables users to utilise different milling heads in one adaptor. Milling cutters can be changed in seconds without retooling, resetting and with minimal downtime. Therefore, users from the mechanical engineering, energy or automotive industry can benefit from an economically and technologically convincing solution that is easy to order, sustainable, high performing and powerful.
