4 Flute Square End Mill, 1/8 in dia, 1/2 in LOC, TICN Solid Carbide

The Titan USA TC90508 is a TiCN-coated micro solid carbide square end mill precision-ground for demanding small-diameter milling work. The Titanium Carbonitride (TiCN) coating delivers outstanding abrasion resistance and hardness — superior to standard TiN — making this end mill highly effective in abrasive materials including hardened steels, cast iron, carbon fiber, and composites. With a 1/8 in cutting diameter and 1/2 in length of cut, the TC90508 is ideal for intricate slot milling, engraving, fine profiling, and small pocket work where precision is non-negotiable. The TiCN coating also reduces friction between the tool and workpiece, extending tool life and enabling higher cutting speeds than uncoated carbide. Four flutes maximize the surface finish and material removal efficiency even at this micro diameter.
