RUKO 215087 - Pack de 10 brocas helicoidales DIN 338, tipo N HSS Co 5 Cobalto, rectificada, con autocentrado (Ø 8,7 mm)

Ruko Din 338 Hss-co 5 Ground Split Point Helical Ø 8.7 Mm Metal Drill Bit 10 Units. The HSS-Co 5 DIN 338 Type VA twist 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 5% cobalt composition provides hot hardness and cutting stability in difficult-to-machine materials.The Type VA geometry combines a split point Type C 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.Product Type: Twist drill bitType: VAStandard: DIN 338Material: HSS-Co 5Material Composition: High-performance high-speed steel with 5% cobaltMachinable Material Strength: Up to 1100 N/mm²Coating/Finish: Bronzed surfaceCutting Direction: Right-hand cutTip Grinding: Type C, split pointPoint Angle: 130°Helix Angle: 36°Flute Profile: NormalCore: ReinforcedTolerance: h8Shank: CylindricalDrilling Depth: 5 x diameterTechnical Strength: High toughness and heat resistanceRecommended Applications or Uses:Drilling in steel up to 900 N/mm²Drilling in steel up to 1100 N/mm²Drilling in stainless steelDrilling in acid-resistant steelDrilling in heat-resistant steelDrilling in aluminumDrilling in brassDrilling in plasticsSecondary use in bronzeSecondary use in cast ironHigh-performance high-speed steel HSS-Co 5 with 5% cobalt.Split point Type C for better centering and reduced feed force.Type VA with a 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
