IMCO - 2017 Comprehensive End Mill Catalog

M233 ROUGHER
STREAKERS
For high-performance machining in aluminum alloys. Special
cutting edge serrations reduce the horsepower needed to
plow through aluminum alloys at high metal removal rates.
The ZrN coating helps reduce chip packing even in heavy
tool engagement cuts.
Tool Tip: M233 Rougher end mills show up to 20% power
reduction from M223 in the same cut.
