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
- EgiAs Coating: for exceptional wear resistance
- Ultra-Fine Grain Carbide: for high wear resistance and toughness
