• Coatings and Surface Treatments Offer Longer Tool Life
• Increase Production Rates • Improve Cutting Characteristics
Coating: TiN (Titanium Nitride)
General purpose coating; ideal for threading of iron-based materials; offers resistance to abrasive materials and adhesive wear.
Coating: TiCN (Titanium Carbonitride)
High hardness; good wear resistance; very 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.
Coating: CrN (Chromium Nitride)
Resists adhesive wear, corrosion and oxidation; suitable for machining titanium and copper; harder than conventional chrome plating.
Coating: TiAlN (Titanium Aluminum Nitride)
A multi-layered coating ideal for carbide 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.
Coating: WC/C (Tungsten Carbide/Carbon)
High lubricity and little adhesive wear (low friction); ideal for applications with adhesive wear and seizure problems (e.g. poor lubrication); high lubricity allows dry machining.
Coating: TiAlN + WC/C ‘HARDLUBE’ (Titanium Aluminum Nitride + Tungsten Carbide/Carbon)
A combination coating that offers low friction and high lubricity, as well as excellent hardness attributes; allows dry threading with reliable chip evacuation, and increased cutting edge wear.
Coating: AlCrN (Aluminum Chromium Nitride)
High hardness with extraordinary wear 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: DLC (Diamond-like Carbon)
Appearance: Dark Gray-Black
Low coefficient of friction combined with high micro-hardness; offers longer tool life through enhanced wear properties; ideal for low lubrication applications and high temperature uses.
Coating: ZrN (Zirconium Nitride)
Appearance: Light Gold/Pale Yellow
Extremely hard all-purpose coating with excellent wear resistance; exceptional abrasion resistance and lubricity; extreme high hardness values; ideal for aluminum and non-ferrous applications.
Surface Treatment: N (Nitride)
Appearance: Dark Gray-Black
A very hard, shallow surface treatment; works well on cast iron, die cast materials, magnesium, bakelite, plastic, zinc; recommended with high-wear, abrasive machining.
Surface Treatment: O (Oxide)
Produces a thin black iron-oxide coating that 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.
Surface Treatment: N + O (Nitride + Oxide)
Appearance: Dull Flat Black
Combination of both treatments listed 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.
