※ 使用NC電腦打洞刀 (捨棄式多功能除料刀)之前請注意下列應用要點
※ 刀桿加工尺寸選擇
● 優先選擇藍色尺寸。
● 選擇涵蓋你需要的加工尺寸，可以減少刀具數量。
● 3xDc~6xDc加工孔徑，請選用99323系列。

※ NC電腦打洞刀為螺旋下刀加工方式，CNC控制器須三軸同動。
| NC Helix Drill | Cutting Parameters ( S & F ) | Formula |
|---|---|---|
 |
 |
Dc = Dia. of drill mm |
| D = Dia. of hole mm | ||
| L = Depth of drilling mm | ||
| Vc = Cutting speed m/min. | ||
| S = Spindle speed r.p.m. | ||
| I = Circular radius mm | ||
| Cutting time ( T ) | fz = Feed rate mm/tooth | |
 |
F = Table feed rate mm/min. | |
| d = Circular diameter (D-Dc) mm | ||
| P = Pitch of helical interpolation mm | ||
| Chip removal Volume rate ( Q ) | T = Cutting time sec. | |
 |
Q = Chip removal volume rate cm³ / min. | |
| Z = Insert tooth |
