200 Series

Tool 200m050FC

Large diameter aluminum work amplifies every mistake. Heat buildup, chatter marks, that distinctive screech when built-up edge finally lets go - the margins for error shrink as cutting diameter grows.

The 200m050FC carries TiB₂ coating specifically because large cuts in aluminum demand it.
TiB₂ runs cooler than uncoated carbide and resists the adhesion that kills aluminum finishes, while avoiding the aluminum welding problems that come with AlTiN.
Three flutes distribute the cutting load across more edges, keeping individual chip loads manageable even at the aggressive feed rates that 5-inch work requires.
The R0.1" corner radius strengthens the cutting edge against the impact loads that come with interrupted cuts and varying depths.
Not sharp enough to chip out, not dull enough to rub.
