RUKO 215040 Pack de 10 brocas helicoidales DIN 338, tipo N HSS Co 5 Cobalto, rectificada, con autocentrado (Ø 4 mm)

Ruko Din 338 Hss-co 5 Ground Split Point Helical Ø 4 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 composition with 5% cobalt 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 behavior during drilling in high-strength materials.Manufactured from HSS-Co 5 with a bronze 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: 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: bronze 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.Recommended applications or 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
