Cemented Carbide Taps ●The unique shape of the special flute design reduces damage to the cutting edge. With the combination of the premium powder ⑤ 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 ofbetween negative rake angleproductand eccentric relief.
