Chip control is good when setting Vc = 260 sfm for MEF11-MEF25, and Vc = 390 sfm for MEF26-MEF48.

Stainless Steel Use a lower Cutting Speed. High Cutting Speeds cause chattering. Cutting Performance when Shouldering MEF Bolt Countersink End Mill is also recommended for shouldering. Vc = 260-390 sfm 1055 DRY Overhang Length: Same as £ in the dimension table 2 Edges Function Fig.1 When shouldering, both side edge and bottom edges function. Both edges wear at the same time depending on D.O.C.. The insert uses 2 edges instead of 4. (Ref. to Fig.1) MEF type's side edge is designed to have a slight clearance for the countersink milling. Therefore, worked side wall is approx. 1° inclined against the vertical face.
