The A Brand AT-1 threadmill is designed with a left-hand helix for a small pitch diameter difference between the hole entry and the bottom of the hole, allowing a delay in gauge-out failure. Longer tool life can be achieved with elimination of “zero cutting” for correcting bending.
Features & Benefits
Unequal Spacing and Variable Lead Flute for reduced vibration
Right-Hand Cut and Left-Hand Helix Geometry increases tool stability
