Drill coatings extend tool life, which equates to the extended service life of each drill and more holes made per drill! While AlTiN Coated Drills have become more widely utilized in heavy duty holemaking applications in recent years, the three most common and widely used drill coatings remain TiN, TiCN and TiAlN. Titanium Nitride Coating (TiN) is a chemical compound composed of titanium and nitrogen that can extend tool life 2-4X that of uncoated drills. Titanium Carbon Nitride Coating (TiCN) is a chemical compound composed of titanium, carbon, and nitrogen that offers high hardness and can extend tool life 4-5X that of uncoated drills. Titanium Aluminium Nitride Coating (TiAlN) is a chemical compound composed of titanium, aluminum, and nitrogen, which offers high heat and oxidation resistance that can extend tool life 4-10X that of uncoated drills. Utilize the drill coating selection charts below to decide if a TiN Coated Drill, TiCN Coated Drill or TiAlN Coated Drill is best suited for your application and material.
