2. Maximum cost per edge for shoulder cutters with a center cutting edge

– A single insert can be used either for center edge or peripheral edge and can be used twice in each position – four total cutting edges for highest insert economy.

3. Flat hole bottom

– Easy to make hole bottoms as flat as possible. Also makes it suitable for counter boring.

  • (1)In the following cases, feed as if the cutter has a single effective cutting edge (ZEFP = 1):
    • Hole making
    • Helical interpolating for holes with a hole diameter (øD) ≤ 1.25x the tool diameter (DC)
    • The axial D.O.C. exceeds APMX2
  • (2)The tool is prone to vibration when the tool overhang exceeds 3.5xD and cause poor part quality. Make sure to use the axial cutting depth (ap) that do not exceed the value indicated in the APMX2 column. Also reduce the cutting speed and feed rate to 50% of the recommended speed.
