RUKO 2150275 Pack de 10 brocas helicoidales DIN 338, tipo N HSS Co 5 Cobalto, rectificada, con autocentrado (Ø 2,75 mm)

Ruko Din 338 Hss-co 5 Ground Split Point Helical Ø 2.75 Mm Metal Drill Bit 10 Units. The HSS-Co 5 DIN 338 VA type spiral drill bit is a high-performance right-hand cutting drill bit designed to offer high thermal resistance and great toughness in demanding drilling operations.Its composition with 5% cobalt provides hot hardness and cutting stability in difficult-to-machine materials.The VA type geometry combines a C-shaped split point tip, a 130° point angle, a 36° helix, and a reinforced core.This configuration improves centering, reduces feed force, and promotes stable performance during drilling in high-strength materials.Manufactured from HSS-Co 5 with a bronzed surface, it features a cylindrical shank, h8 tolerance, and a drilling depth of 5 x diameter.It is a technical solution for professional work where precision, heat resistance, and consistent performance are required in compatible metallic and plastic materials.Technical characteristics:Product type: Spiral drill bit.Type: VA.Standard: DIN 338.Material: HSS-Co 5.Material composition: High-performance high-speed steel with 5% cobalt.Machinable material strength: up to 1100 N/mm².Coating/finish: Bronzed surface.Cutting direction: Right-hand cut.Point grinding: C shape, split point.Point angle: 130°.Helix angle: 36°.Flute profile: Normal.Core: Reinforced.Tolerance: h8.Shank: Cylindrical.Drilling depth: 5 x diameter.Technical resistance: High toughness and heat resistance.Applications or recommended uses:Drilling in steel up to 900 N/mm².Drilling in steel up to 1100 N/mm².Drilling in stainless steel.Drilling in acid-resistant steel.Drilling in heat-resistant steel.Drilling in aluminum.Drilling in brass.Drilling in plastics.Secondary use in bronze.Secondary use in cast iron.High-performance HSS-Co 5 high-speed steel with 5% cobalt.C-shaped split point tip for better centering and reduced feed force.VA type with reinforced core and 36° helix for difficult-to-machine materials.130° point angle for drilling in stainless steel and high-strength steels.Drilling depth of 5 x diameter with h8 tolerance and cylindrical shank. tradeinn Bricoinn
