A Brand® AT-1 (16630)

Advanced Performance One Pass Thread Mill

Overview

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.
