  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 ●A spectrum of colours (After 20 Holes) Sparkling colours are a result of the special coating technique. Extensive Adhesion Drill : ø8 (5D) Work Material : ADC12 Cutting Conditions : vc=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 pre- Drilling穴 treatment technology ensure superior diamond layer adhesion. あ け Solid Special ■ Characteristics ■ SUMIDIA Coat Application Examples Indexable ●Provides ultra-flat surfaces required for cutting CFRP as well SUMIDIA Coated Drill Competitor's Diamond Coated Drill Reamer as a fine diamond layer with high strength and wear resistance. Brazed Others After After 600 Holes 50 Holes Able To Continue Peeling And Burrs Work Material: CFRP Tool : SUMIDIA Coated Drill ø6.35mm Competitor's Diamond Coated Drill ø6.35mm Cutting Conditions : vc=130m/min f=0.075mm/rev H=15mm Through Hole Dry J7
