L Note 1) Please pay special attention on the depth of cut when using the short edge type. Note 2) When using the G1-breaker wiht coated grades VP15TF, MP6120 or MP9120, reduce the feed rate by 20%. Note 3) For more information on "No.", please refer to page L201 for cutting speed.

A3 is the depth of cut for the full dual blade portion at the end of the

cutting edge. Beyond the range of A3 where overlapping occurs, there is an 6DC area where the cutting edge becomes single bladed, not forming 4.5DC full dual blade configuration. BT50BT50 As such, please pay special attention to the relationship between 3DC depth of cut and feed. BT40

In general, the edge at the border of cut tends to suffer from1.5DCHSK63
damages. At large depth of cut operations, applying the following*
depth of cut (t), at which the edge is full dual bladed at the borderDC= Cutting Edge
