(ote 2) When using the G1 breaker (V15TF), please reduce the eed rate by 20%. (ote 3) For more inormation on "o.", please reer to page 11 or cutting speed. A3 is the depth o cut or the ull dual blade portion at the end o the cutting edge. Beyond the range o A3 where overlping occurs, there is an area where the cutting edge becomes single bladed, not orming ull dual blade coniguration. As such, please pay special attention to the relationship between depth o cut and eed. In general, the edge at the border o cut tends to suer rom damages. At large depth o cut operations, plying the ollowing depth o cut (t), at which the edge is ull dual bladed at the border o cut, is recommended to prevent damage to the cutting edge.

5 y For Drilling and lunging a Drilling athe recommended drilling depth is less than.5. ause step eed when drilling ( inch) to ensure that the chips are eectively broken. a Use internal or external cooling to ensure that the chips disposal is suiciently achieved. a The chips generated can discharge in any direction, so ensure that adequate sty precautions are taken. a lunging Depth o Cut in the Radius Direction eck Feed athe eed or plunging is the same as the eed or drilling. a o step eed necessary. a lease reer to the ollowing table or the depth o cut at plunging operations.

(ote 1) When using the G1 breaker (V15TF), please reduce the eed rate by 20%. (ote 2) For more inormation on "o.", please reer to page 11 or cutting speed. y For Ramping 3 a When machining steel the recommended ramping angle is 3. I a ramping angle larger than 3 is used, then the chips may not be broken eectively resulting in chips wrping around the tool. a When ramping, it is recommended to reduce the eed rate by 40%.
