1-1/4" OD x 1-1/4" Shank OD x 6" LOC x 8-1/2" OAL 3-Flute SE Cobalt HSS Aluminum CKN Roughing End Mill 40° H CC SQ Extra-Long Bright Finish (Uncoated) EDP #11396

1-1/4" OD x 1-1/4" Shank OD x 6" LOC x 8-1/2" OAL 3-Flute Single End Cobalt High-Speed Steel (HSS) Aluminum CKN-Style Roughing End Mill, 40° Helix, Center Cut, Square End, Extra-Long Length, Bright Finish (Uncoated).

This 3-flute cobalt high-speed steel roughing end mill combines HSS toughness with improved hot hardness for demanding material-removal applications. The aluminum roughing geometry is designed for productive stock removal in aluminum and other suitable non-ferrous alloys, with flute space intended to support chip evacuation. The center-cutting geometry also supports controlled axial entry, ramping, and pocketing when appropriate for the workpiece and setup. The CKN designation identifies the manufacturer-specified roughing profile for this series.

The bright, uncoated finish provides a direct cutting edge for roughing operations where an added coating is not required.
