COATINGS / SURFACE TREATMENTS TECHNICAL DATA • Coatings and Surface Treatments Offer Longer Tool Life • Increase Production Rates • Improve Cutting Characteristics Coatings Coating Appearance Characteristics/Applications TiN Gold General purpose coating; ideal for threading (Titanium Nitride) of iron-based materials; offers resistance to abrasive materials and adhesive wear. TiCN Blue-Gray High hardness; good wear resistance; very (Titanium Carbonitride) tough coating for difficult-to-machine steel alloys when tools encounter excessively stressed cutting edges, and highly abrasive and/or gummy materials such as cast iron, brass and aluminum alloys; use when high feed and speed rates are desired. CrN Silver-Gray Resists adhesive wear, corrosion and oxidation; (Chromium Nitride) suitable for machining titanium and copper; harder than conventional chrome plating. TiAlN Violet-Gray A multi-layered coating ideal for carbide (Titanium Aluminum Nitride) and high speed tooling; excellent oxidation resistance allows high speed and semi-dry or dry machining; best suited for threading cast iron, stainless steel, nickel-based high temp. alloys, and titanium alloys; heat resistant. WC/C Black-Gray High lubricity and little adhesive wear (low (Tungsten Carbide/Carbon) friction); ideal for applications with adhesive wear and seizure problems (e.g. poor lubrication); high lubricity allows dry machining. TiAlN + WC/C ‘HARDLUBE’ Black-Gray A combination coating that offers low friction (Titanium Aluminum Nitride + and high lubricity, as well as excellent hardness Tungsten Carbide/Carbon) attributes; allows dry threading with reliable chip evacuation, and increased cutting edge wear. AlCrN Silver-Gray High hardness with extraordinary wear (Aluminum Chromium Nitride) resistance under extreme stress; AlCrN’s unique combination of hardness and heat resistance permits high performance; recommended for finishing exotic materials, titanium, hastelloy, etc., gray and ductile iron parts, as well as applications in mild and high carbon steels.

Coating Appearance Characteristics/Applications DCL Dark Gray-Black Low coefficient of friction combined with high (Diamond-like Carbon) micro-hardness; offers longer tool life through enhanced wear properties; ideal for low lubrication applications and high temp. uses. ZrN Light Gold/ Extremely hard all-purpose coating with (Zirconium Nitride) Pale Yellow excellent wear resistance; exceptional abrasion resistance and lubricity; extreme high hardness values; ideal for aluminum and non-ferrous applications. Surface Treatments Surface Treatment Appearance Characteristics/Applications N Dark Gray-Black A very hard, shallow surface treatment; works (Nitride) well on cast iron, die cast materials, magnesium, bakelite, plastic, zinc; recommended with high- wear, abrasive machining. O Black Produces a thin black iron-oxide coating that (Oxide) enhances lubricity and reduces friction; deters chip welding and galling by acting as an insulator between tool and workpiece; recommended for use in ferrous materials, low carbon material, leaded steel, and gummy materials. N + O Dull Flat Black Combination of both treatments listed (Nitride + Oxide) previously, affording the characteristics of both. Has anti-galling properties with high wear resistance. Recommended for highly abrasive and penetration-resistant materials. Not suited for soft materials like (pure) aluminum, brasses, magnesium and similar non-ferrous materials.
