The MULTI-MASTER Advantage
ISCAR offers oval- and lens- shape endmills in
diameter ranges of 8 - 16 mm and .312" - .500". In
addition to their availability in sold carbide design
configurations, the new barrel endmills have been
manufactured as exchangeable carbide heads with
MULTI-MASTER threaded adaptation.

Additional factors in favor of applying the MULTI-
MASTER concept to barrel endmills are economic
feasibility and sustainability. Due to the complicated
shape of its cutting edges, a barrel endmill is designed
as a throwaway tool - when the wear limit is reached,
the entire carbide endmill simply becomes waste. In
contrast to solid tools, the MULTI-MASTER design
provides a valuable option for careful and cost-
effective use of cemented carbide materials. And,
of course, a rich variety of available MULTI-MASTER
shanks, reducers and extensions enables optimal
assembly of a required tool from these elements.
At present, barrel milling cutters are not in incredibly
high demand by the metalworking industry; they
are intended for very specific parts and effective
application of such cutters requires highly engineered
multi-axis machines and, especially important,
leading-edge CAM systems. However, advanced
workpiece manufacturing technologies (such as metal
injection molding, 3D printing, investment casting and
close-tolerance forging), innovative machine tools,
and a quantum leap in digitizing of manufacturing
will increase the needs for finishing complex surfaces
with minimum machining stock. In this light, ISCAR's
specialists estimate that barrel endmill consumption in
the metalworking industry will increase exponentially,
and cutting tool manufacturers should be shaping up
to what is evidently a promising new industrial trend.
