200 Series

Tool 200i156LC

Small diameter aluminum work tests your setup twice. First the usual aluminum problems. Chip welding, built-up edge, heat that turns precision into scrap. Then the deflection issues that come with any tool under 3/16 inch diameter.

The 200i156LC runs 0.1563 inch cutting diameter with three flutes and TiB₂ coating.
Three flutes distribute cutting load while maintaining reasonable feed rates, keeping individual chip loads manageable enough to prevent aluminum from sticking to the edge.
TiB₂ coating adds hardness and thermal barrier properties without the aluminum affinity problems you get with AlTiN coatings.
The R0.004 corner radius strengthens the cutting edge against chipping while leaving enough sharpness for clean entry into the cut.
Designed for aluminum, copper, and plastics where small diameter precision matters.
