Note 2) When using wiper insert, please reduce the feed per tooth to half the normal rate. y Usable cutting edge width of wiper inserts The width of the wiper insert itself is .217 inch, however the actual functioning cutting edge width after installation to the body is .177 inch, as shown in the diagram. With one wiper insert, it is possible to machine up to fr=.157 inch feed per revolution. When exceeding fr=.157 inch, use two or more wiper inserts. Note that there is a possibility to exceed fr=.157 inch when using a holder with more than 24 inserts. .157" L081 INDEXABLE MILLING
