What are the features of the AT-1? < Thread Mill>

The AT-1 uses a right-hand blade and a left-hand twist to prevent tool deflection , allowing conventional two-pass machining to be machined in one pass.

The AT-1, which has a right-hand blade and a left-hand twisted groove, has the advantage that the effective diameter difference between the mouth of the machined screw and the back side is small, and it is slow to gauge out. In addition, it eliminates the need for zero cuts to compensate for deflection and has a long service life.

wear resistance ・In addition to heat resistance, the EgiAs coating, which has excellent toughness, achieves long life and life stability.

AT-1 is compatible with a wide range of materials, including mild steel, carbon, SCM, SUS, FC, copper, tempered steel up to 45HRC, and rolled aluminum.
