Hole Making HP Drilling Tool Series
Grade Introduction
Carbon steel, alloy steel, cast steel/forged steel
Basic grade
AP301U P25(P15-P35) PVD coated carbide grade, suitable for drilling of steels, stainless steel. High strength and wear resistance ultra fine carbide substrate with nanostructured PVD coating in controllable layers, high coating adhesion, wear-resistance and strength. AP351U P35(P30-P45) PVD coated carbide grade for drilling of steels, stainless steel, heat-resistant alloys under unstable working conditions. Composite nanostructured coatings are deposited on the high toughness carbide substrate, offering better wear resistance and impact resistance.
AP351M P30(P25-P40) PVD coated carbide grade. Suitable for drilling of steels, stainless steel, heat-resistant alloys in general working conditions. Good toughness and wear resistance ultrafine crystalline substrate combined with nanostructure PVD coating. Good thermal cracking resistance, wear resistance and coating strength.
Austenitic/artensitic stainless steel
Basic grade
AP351M M30(M20-M35) PVD coated carbide grade. Suitable for drilling and machining of steels, stainless steel, heat-resistant alloys under general working conditions. Nanostructured coatings are deposited on the high strength, high wear resistance ultra-fine grain structure carbide substrate. Good thermal cracking resistance, wear resistance and coating strength.
Heat-resistant alloys (Ni-based), titanium alloys
