Features of Milling Inserts

Cross sections of the
Type Features Work materials
cutting edge (Outline figure)
• The inserts have functional curvatures at cutting Land width
edges and relief faces.
MJ • General inserts with both impact resistance and Rake angle
cutting force reduction. 9
• Allows super high feeds as high as 1.5 to 2 times Land width
those of general purpose inserts.
HJ • Superior impact resistance and low cutting forces, Rake angle
even under high machining load at high feeds. P Steels TAC Mills
(Maximum depth of cut: .078 in) K Cast irons
Ductile cast irons Land width
• Lowered cutting force compared with MJ type ( M Stainless steels)
ML • Applicable when chattering occurs in using MJ Rake angle
type.

Land width
• Suitable for high feed milling.
MH • Available when chipping occurs in using MJ type. Rake angle
• Toughness priority.

Land width
• Low cutting force compared with MJ type M Stainless steels
MS • For stainless steels (and mild steels) (Mild steels) Rake angle
• Applicable for burr reduction.

• For non-ferrous metals such as aluminum alloys etc. N Aluminum alloys Rake angle
AJ • Inserts have sharp edges and mirror like rake faces. (Non-ferrous metals)
• Applicable for burr reduction.
