Face mills for heavy millingMFLN

Tough 4-edge tangencial inserts provide high reliability on heavy milling at large

depths of cut and high feed rates. 3 cutting edge angles (incl. MFLN45 and MFLN70)

optimized for various machining applications.

1 Tough and reliable inserts for stable heavy milling

22 mm long inserts offer increased rigidity

Tangentially mounted inserts provide 2 cutting Obtuse edge design

edges on both sides

Increases the cutting edge angle only at the tip to maintain both strength and sharpness

Corner chamfer

only available on MFLN90 M Both general corner-R type and chamfered corner type available Conventional Prevents chattering and insert fracturing

Convex cutting edge ridge Reduced impact forces when entering the workpiece

Wide flat mounting surface

Hold an insert firmly in heavy milling

Tangentially mounted inserts increase rigidity Cutting forces when entering the workpiece (internal evaluation)
