Drill Coating

AURORA COAT

• General Features The AURORA COAT is a high hardness, low friction layer of DLC (Diamond Like Carbon). AURORA COAT is a thin-layer coating that provides greatly improved adhesion resistance when drilling aluminum alloys and non-ferrous metals and ensures long, stable tool life when used in combination with specially designed drill shapes.
• Characteristics
• AURORA COAT Application Examples
• Ultra-smooth DLC thin-layer coating with low coefficient of friction High resistance to adhesion and significantly reduced cutting AURORA COAT resistance when drilling aluminum alloys and non-ferrous metals. Super MultiDrill NHGS Type
• High coating strength withstands tough cutting conditions (After 100 Holes) Special coating technique improves coating adhesion Clean Cutting Edge With No Adhesion and is world's first application on cutting tools.
• Employed on Super MultiDrill NHGS type and SumiDrill Comp. WDX type Drill
• (After 20 Holes)

A spectrum of colours Extensive Adhesion Sparkling colours are a result of the special coating technique. Drill : ø8 (5D) Work Material : ADC12 Cutting Conditions : v c=200m/min f=1.0mm/rev H=32mm Internal Coolant

SUMIDIA Coat

• General Features Our proprietary crystalline diamond coating technology achieves J wear resistance over 10 times that of uncoated carbide. Special diamond coating alloy and proprietary coating pretreatment technology ensure superior diamond layer adhesion.

• Characteristics
• Provides ultra-flat surfaces required for cutting CFRP as well as a fine diamond layer with high strength and wear resistance.
