Description

STI 2638-5XN-03 Carbide Drill Shank 0.3150 TiAlN 0.2638 6.70MM Drill Dia 1.5980 40.59MM 5.0XD-8.0XD Flute Length Carbide Titanium aluminium nitride (TiAlN) or aluminium titanium nitride (AlTiN; for aluminium contents higher than 50%) is a group of metastable hard coatings consisting of nitrogen and the metallic elements aluminium and titanium. This compound as well as similar compounds(such as TiN and TiCN) are most notably used for coating machine tools such and endmills and drills to change their properties, such as increased thermal stability and/or wear resistance. Four important compositions (metal content 100 wt.%) are deposited in industrial scale by physical vapor deposition methods:
