How does it work?

High-feed milling creates significant chip thinning due to an extreme lead angle. Feed rates must compensate for this to maximize productivity. The figure at left shows an example of this condition.

Adjusting feed rates to account for chip thinning creates cutting conditions that provide very high feeds (IPM), but at lighter depths of cut (DOC). See the specific operating instructions for each size of high-feed insert to optimize these cutting tools.

Multiple sizes - Multiple options

Mini-feed inserts have the smallest IC (inscribed circle) and smallest cross section. 

.500" - 1.000" OD
8mm IC
3 usable edges
"D" cutting edge
.030" max. DOC

Mid-feed inserts have a stronger cross-section than the mini-feed, but are smaller than the heavy-feed. 

R3 Mid-Feed Cutters & Inserts

1.000" - 3.000" OD

10mm IC
4 usable edges
"T," "D" or "F" cutting edge
.045" max. DOC

Heavy-feed inserts have the strongest cross-section of the line. 

R4 Heavy-Feed Cutters & Inserts

1.250" - 6.000" OD
12mm IC
4 usable edges
"T," "D" or "F" cutting edge
.060" max. DOC
