The following table of tool life values was obtained from several tool life tests carried out by drilling steel with carbide drills. The drill diameter is 8 mm and the hole depth is 25 mm. The mean of the tool life corresponding to different speeds and feeds are given in the table.
| V (m/min) | F (mm/rev) | T (min) | |
| 1 | 70 | 0.15 | 120 |
| 2 | 70 | 0.25 | 105 |
| 3 | 140 | 0.15 | 24 |
The value of Taylor's constant using modified Taylor's tool life equation is ___________.
