New system size for MaxiMill 491

Now even more flexibility with 90° shoulder milling

With 8 usable cutting edges per insert, a precise 90° profile of the work piece and a durable nickel-coated tool body, the MaxiMill 491 system is the best choice for all applications in the field of shoulder and full-slot milling. The system was developed by Cutting Solutions by CERATIZIT, the competence brand for innovative tooling solutions from the CERATIZIT Group. Now the system has been intelligently extended with a 9 mm size insert.

With the 8 cutting edges of the 90° shoulder milling system the carbide experts from Reutte, Austria, have struck out on completely new technological paths. The system is characterised by extremely easy handling, and enables the insert to be quickly changed inside the machine. This significantly reduces machine downtime, but in other respects as well the system offers decisive advantages. The precision-ground inserts are extremely stable and soft-cutting, thanks to state-of-the-art Dragonskin coating technology, which makes them suitable for the most demanding requirements. Thanks to the soft cutting action of the positive insert geometry, excellent surface quality and dramatically increased tool life can be achieved. Furthermore MaxiMill 491 scores well in that its 8 usable cutting edges come at a very attractive price per edge.

System size extension

MaxiMill 491 was launched in size 12 mm, with a nominal diameter range from 32 to 160 mm and a corner radius of 0.8 mm. The range has already been extended by the addition of corner radii measuring 1.2 mm, 1.6 mm and 2.0 mm. The new 9mm insert size now brings even more flexibility for all applications. Thanks to the smaller size, more inserts can be mounted in the tools, thus achieving even longer tool life and higher chip removal rates. Power consumption is also reduced significantly while the tool remains the same. This makes the new system size particularly suitable for machines with lower power.

Watch product videos now

Two new product videos available at or on the CERATIZIT Youtube channel, show why the 90° MaxiMill 491 with double-sided inserts is indispensable for your shoulder and full-slot milling operations. In addition to the machining of steel, stainless steel and cast iron the second video gives an impressive demonstration of the machining of an aluminium component.
