Product Features

  • In the tapping of aluminum alloy castings and their equivalent, the AXE-HT produces an excellent improvement in durability and performance with YAMAWA's unique flute design.
  • The unique shape of the special flute design reduces damage to the cutting edge. With the combination of the premium powder HSS (characterized by high abrasion resistance and heat resistance) and the special coating, tool life has increased 5 times compared with the conventional tap designed for aluminum.
  • Cutting edge damage diminishes on the flutes. Dimensional change in the internal thread pitch diameter is reduced while surface finishes are improved.
  • Suitable from medium to high speed by offering the optimal combination of negative rake angle and eccentric relief.Comparison of tool life between AXE and LA-O (previous product )
