Alfa USA TiN coated jobber length drill bits are ideal for production work or repetitive drilling in hard metals, hardened stainless and other difficult to drill materials. Titanium Nitride coating (TiN) is a gold colored ceramic coating applied by physical vapor deposit (PVD), ensuring high hardness with low friction. The super hard surface with high lubricity increases tool life. 135 degree self-centering split point reduces thrust.
