| Forms E and F | Form T |
| Forms E and F with automatic tool change are also variations of forms A and B. | Form T shanks are similar to form A, but these tools offer a tighter keyway that |
| These forms are intended for high-speed machining. Design features, such as drive | reduces cutting height variation. This gives form T improved repeatability over |
| slots, the orientation notch, and chip holes, have been removed to help eliminate | form A. These shanks have new centerline technology for variance and high |
| imbalance. As a result, these forms are driven by the locking taper and are suitable | productivity. They are also available in a wide range of standard toolholders. |
only for light machining applications such as high-speed metalcutting and woodworking machines. Form E offers five different shank sizes ranging from 25–63mm (.984–2.480") flange diameter. There are three shank sizes for form F from 50–80mm
(1.969–3.150") diameter on the flange.
