200 Series

Tool 200i188C

Small diameter aluminum work separates careful setups from broken tools. At 0.1875", there's less room for error when heat builds or chips pack. The typical signs show up faster: chatter marks, size drift, premature wear.

The 200i188C addresses this with 3-flute geometry that distributes cutting load across more edges while maintaining reasonable feed rates.
Lower chip load per tooth reduces the tendency for aluminum to weld to the cutting edge.
TiB₂ coating adds wear resistance during more demanding passes without the aluminum affinity issues that come with AlTiN coatings.
The R0.004" corner radius strengthens the cutting edge against chipping while maintaining sharp cutting action.
High helix angle moves chips out before they can pack or reweld to the work surface.
