Climb Milling

Strongly recommended over conventional milling in order to prevent the inserts from rubbing when entering the part.  With Metal Master milling cutters, rubbing will quickly lead to increase friction and heat buildup, drastically reducing insert and cartridge life.

Skim Cutting

Due to the unique cutting action of Metal Master milling cutters, the part should be lowered .005" (0.10mm) to .010" (0.25mm) on 'return' passes to prevent skim cut.  If the cutter is allowed to skim cut, insert life will be drastically shortened.

Width of Cut

Optimum width of cut is generally two-thirds of the diameter of the cutter.
