FOR DRILLING AND PLUNGING Drilling The recommended drilling depth is less than 0.5DC. Use step feed when drilling (0.25 0.5mm) to ensure that the chips are effectively broken. Use internal or external cooling to ensure that the chip disposal is sufficiently achieved. The chips generated can dispel in any direction, so ensure that adequate safety precautions are taken. Plunging Depth of Cut in the Radial Direction The feed for plunging is the same as the feed for drilling. No step feed necessary. I Please refer to the following table for the depth of cut at plunging operations.

Note 2) When using G1 breaker (VP15TF), please reduce the feed rate by 20%. Note 3) For the details of No., Please refer to the cutting speed on page M157. FOR RAMPING When machining steel the recommended ramping angle is 3°. If a ramping angle larger than 3° is used, then the chips may not be broken effectively resulting in chips wrapping around the tool. During ramping, it is recommended to reduce the feed rate by 40% from the cutting conditions. M M161 INDEXABLE MILLING
