OSG EX Gold Drill, Regular for General Machining, 5.2, 60552, EX-GDR-5.2, 1 piece

Catalog number: EX-GDR-5.2 Features: ●High versatility, realizing non-step high-speed machining up to 4 to 5 times the blade diameter. ●The center of the drill tip adopts a new R blade shape. ●High speed and high feed are possible. Step cutting is not required because the chips are broken into transition fracture shapes. ●TiN coating with excellent wear resistance and adhesion resistance is used. ●The groove form is a high-rigidity type with a thick core. ●The position accuracy of the processed hole is stable, so punching and centering are not required. Applications: ●Cutting materials: medium and high carbon steel, alloy steel, tempered steel, tool steel, cast iron, ductile cast iron, aluminum drawn material, aluminum alloy casting, magnesium alloy. Specifications: ●Blade diameter (mm): 5.2 ●Groove length (mm): 52 ●Total length (mm): 96 ●Shank diameter (mm): 6 ●Effective machining depth: 5D (blade diameter x 5 times) ●Surface treatment: TiN coating Material/Finish: ●Cobalt high-speed steel (HSS-Co)
