Note! Fully tighten insert screws before snugging down on clamp screws. Failure to tighten in correct order may result in insert/cutter breakage.

R4 Heavy-Feed Shell Mills

All Shell Mills 3" diameter and smaller are transitioning to a thru-coolant style. To specify thru-coolant option when ordering, add a "C" to the end of the part number. Stock not guaranteed.

Heavy-Feed Inserts

T-Land Cutting Edge "T" inserts have a reinforced cutting edge for steels, irons and hard milling.
Dished Cutting Edge "D" inserts have a positive cutting geometry, designed to reduce cutting forces and heat. This edge is suitable for all materials.
"F" Cutting Edge "F" inserts are specially reinforced for the heaviest feeds and most abusive applications in steels or irons (available in grade DMK30 only).

* A special corner radius value is required for correct programming of a high-feed insert. Using the program radius avoids gouging of the corners in the workpiece material.
The high-feed insert will naturally leave a small amount of extra material at the bottom-most layer of the cut, at the intersection of the wall and pocket floor.
RHINO-FEED inserts are labeled with dots to indicate die position during pressing. For the most accurate runout when loaded into the cutter body, make sure each insert is loaded with the corresponding edge.
