Note 1) The recommended ramping feed is .002 IPT or under.*
1 L (Max. Depth of Cut =.591" / tan %). Cutters' moving distance until depth of cut reaches APMX at a maximum ramping angle.
Maximum depth of cut A type is .827", B type is .803".*
L 2 The maximum diameter when machining a blind hole with a flat face using a corner radius of .031" for A type and .157" for B type. Other than that, find with the below formula. {(cutting edge diameter DC) ─(corner radius) ─0.3)}×2 *3 The minimum diameter when machining a blind hole with a flat face using a corner radius of .031" for A type and .157" for B type. Other than that, find with the below formula. {(cutting edge diameter DC) ─(corner radius) ─(Width of wiper edge BS) ─ 0.1)}×2
