MaxiMill 491

Double-sided 90° shoulder milling system

With eight usable cutting edges per insert, a precise 90° profile on the workpiece and a durable, nickel-plated base body, the MaxiMill 491 shoulder milling cutter offers maximum performance and cost-effectiveness. A new 9 mm size complements the existing selection.

The MaxiMill 491 was initially launched as a 12 mm system with a nominal diameter range of 32-160 mm and a corner radius of 0.8 mm.

Tool holders are available for face mills, end mills, and screw-in cutters. F-M-R chip breakers combined with the latest DRAGONSKIN grades are suitable for a diverse range of material applications, including steel, cast iron, stainless steel (ISO P-M-K), and aluminum.

The product range has been expanded to cover 1.2 mm, 1.6 mm and 2.0 mm. With 9 mm indexable inserts, we have increased the system range to offer even more application flexibility. This smaller size allows more indexable inserts to be attached to the tool holders, which in turn, delivers longer tool life and higher chip removal rates. Furthermore, power consumption can be slashed while still using the same tool.
