Quick and easy replacement of the tool’s front piece, the part of the tool that typically becomes worn most quickly, means that the M4258 cutter can continue to be used cost effectively.

M4258 system inserts are available in square format with four cutting edges, and as rhombic inserts with two cutting edges, for not only porcupine milling cutters, but for face, shoulder, chamfer and T-slot milling cutters in the M4000 cutter range. In addition, different insert geometries, such as the D51 anti-vibration type, allow the tool to be deployed in difficult cutting conditions, while Tigertec Gold inserts are available within the range to produce further tool life benefits.

Walter Capto C6 and C8 interfaces ensure a positive-locking connection for a tool that provides good chip clearance and internal cooling for high process reliability and safe chip evacuation, says the company.

Offered in diameters from 50 to 80 mm, the M4258 cutter with M4000 inserts is suitable for applications in cast iron, steel, stainless steel and materials with difficult cutting properties.
