200 Series

Tool 200i188M010C

Small diameter aluminum work amplifies every setup mistake. Heat builds faster, chips pack tighter, and built-up edge forms before you notice the finish degrading. The tolerances don't forgive much at 3/16".

The 200 Series uses three flutes to distribute cutting load while maintaining reasonable feed rates in aluminum, copper, and plastics.
Lower chip load per tooth reduces adhesion tendencies that create built-up edge.
High helix geometry moves chips out before they weld to the cutting edge.
This 3/16" diameter end mill carries TiB₂ coating for demanding passes where standard uncoated tools wear too quickly.
The R0.01" corner radius strengthens the cutting edge without sacrificing detail definition in tight radius work.
TiB₂ handles the thermal cycling better than nitride coatings on aluminum.
