OSG High-coating Drill Nexus Drill Stub Type Cutting Diameter 4.4mm 8650440 NEXUS-GDS-4.4 1 piece

Catalog number: NEXUS-GDS-4.4 Features: ●This drill for shallow hole machining has a shorter overall length than regular drills and increased rigidity. ●WD1 coating suppresses peripheral margin wear and achieves a long life in the high-speed range. ●Strong twist (35 to 40°) and unique groove form minimize heat generation and work hardening associated with cutting. ●High-toughness high-speed steel is used as the base material to suppress chipping of the cutting edge, which is particularly likely to occur when machining stainless steel. Applications: ●Cutting materials: Stainless steel, low and medium carbon steel, copper alloy, aluminum drawn material, aluminum alloy casting, magnesium alloy. ●Cutting materials: Stainless steel, mild steel, copper, aluminum alloy. Specifications: ●Blade diameter (mm): 4.4 ●Groove length (mm): 24 ●Overall length (mm): 68 ●Shank diameter (mm): 6 ●Effective machining depth: 2D to 3D (blade diameter x 2 to 3 times) ●Surface treatment: WD1 coating ●WDI coating Material/Finish: ●High-speed steel (HSSE)
