The M4258 modular helical milling cutter from Walter USA, the most recent addition to its M4000 family of high-performance helical milling cutters, promotes cost efficiency and process reliability in slot milling and can be used for ramping, pocket milling, shoulder milling and circular interpolation as well. Versatility also extends to materials, handling ISO material groups P, M, K, and S.

Tiger-tec Gold and six Tiger-tec Silver​​​ grades are available, covering nearly all ISO groups. The modular design of the M4258 features an exchangeable front-end piece that can be replaced when this section of the body is worn or damaged. The tongue and groove connection with the register pin promotes precise and safe positioning of the front end. Features like this, combined with four/two cutting edges per insert, boost cost efficiency and reduce procurement and inventory costs and requirements, the company says.

Process reliability is enhanced by several features. Effective design and highly positive insert geometry lower power requirements and costs. An internal coolant supply in the standard offering adds versatility along with superior chip removal. Operating under low cutting pressure, its compact length and effective design promotes smooth operation. This reduces oscillation and vibration, suiting it to a variety of unstable machining conditions. The M4258 has an approach angle of 90 degrees and a diameter range of 2.0", 2.5", and 3.0" (50, 63, and 80 mm). Interfaces are Walter Capto C6 and C8.
