OSG EX Gold Drill, General Machining Stub Type, Blade Diameter 5.1mm, 60051, EX-GDS-5.1, 1 Piece

Catalog number: EX-GDS-5.1 Features: ●High rigidity groove form and stub groove length provide high efficiency and high precision, making it ideal for tapping pilot holes and lathe processing. ●The center of the drill tip uses a new R blade shape based on Hosoi theory. ●High speed and high feed are possible. The chips are broken into transition fracture shapes, eliminating the need for step cutting. ●TiN coating is used, which has excellent wear resistance and adhesion resistance. ●The groove form is a high rigidity type with a thick core. ●The positional accuracy of the processed hole is stable, so punching and centering are not required. Applications: ●Cutting materials: low, medium, and high carbon steel, alloy steel, cast iron, tempered steel, tool steel, ductile cast iron, aluminum alloy casting, Inconel, magnesium alloy. Specifications: ● Blade diameter (mm): 5.1 ● Groove length (mm): 26 ● Total length (mm): 70 ● Shank diameter (mm): 6 ● Effective machining depth: 3 to 4D (blade diameter x 3 to 4 times) ● Surface treatment: TiN coating Material/Finish: ● Cobalt high speed steel (HSS-Co)
