Cast Iron Powerhouse

The M4070 heavy duty face mill has powerful features trusted to continuously perform in demanding machining conditions while running at high cutting parameters on uneven, non-uniform surfaces.

The M4070 is equipped with hardened anvils and tangentially-mounted inserts to power through forged and cast surfaces with uneven stock.

 

 

Features and Benefits

  • Positive cutting edge geometry to enable smooth cutting
  • Tangential design with an M6 insert clamping screw for secure insert seating and predictable performance in high depth of cut (DOC) applications
  • Hardened anvils for extended tool body life
  • Enlarged chip gash design for clean chip evacuation

-MH Inserts are Offered in Two Grades: WK15CM and WP35CM

M4070 Series Insert (ISO Catalog # LNGU201012SNMH | MM # 6852418)

WK15CM 

WK15CM is a wear resistant grade with a balanced toughness for general milling of cast irons. This grade achieves the best results in dry machining but can also be used in wet conditions.

WP35CM

WP35CM is a general grade with a wide range of applications in the milling of steels and cast irons. This grade also performs best in dry machining but can be used in wet conditions.
