YG-1 SM28309 39.00mm Carbide (C5) SM Point Throw-Away Drill Insert TIALN-Coated

YG-1 SM28309 Spade Drill 39.00MM CARBIDE (C5) SM POINT THROW-AWAY DRILL Insert TIALN-COATED Carbide C5 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:
