The ECP-3/4L family offered by Iscar Metals, Inc. incorporates a serrated cutting edge that features flat peaks, which are said to provide good surface finishes.
Recommended for machining austenitic and martensitic stainless steel at up to 2×D depth of cut, the SolidShred is available with three and four 38-degree helix flutes in grade IC900. All end mills in this series feature long shanks with reduced neck diameters, which according to the company, enable machining along high shoulders at high feeds. Because of force distribution and the splitting characteristic, the end mills are suitable for use on low-power machines—CAT40, BT40 and ISO40.
These tools can also be used when machining alloy steels.
