RUKO 215080 Pack de 10 brocas helicoidales DIN 338, tipo N HSS Co 5 Cobalto, rectificada, con autocentrado (Ø 8 mm)

Ruko Din 338 Hss-co 5 Ground Split Point Helical Ø 8 Mm Metal Drill Bit 10 Units. The HSS-Co 5 DIN 338 Type VA twist drill bit is a high-performance drill bit with a right-hand cut, designed to offer high thermal resistance and great toughness in demanding drilling operations.Its 5% cobalt composition provides hot hardness and cutting stability in difficult-to-machine materials.The Type VA geometry combines a C-form split point tip, a 130° point angle, a 36° helix angle, 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 features:Product type: twist 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-form, 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-form split point tip for better centering and reduced feed force.Type VA 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
