RUKO 2141125 - Pack de 5 brocas helicoidales DIN 338, tipo N HSS, fresada-rectificada, con autocentrado (Ø 11,25 mm)

Ruko Hss Din 338 Type N Serie 214 11.25mm Drill Set 5 Pieces. The HSS DIN 338 Type N twist drill bit is a high-performance standard drill bit manufactured from high-strength high-speed steel. Its fully ground construction provides precise concentricity and stable drilling behavior.The Type N geometry features a ground normal helix point, a 118° point angle, and a 20° to 30° helix angle. This configuration allows for good centering, reduces the pressure needed during feed, and promotes regular cutting in commonly machined materials.Made from uncoated HSS, it has a right-hand cut, a cylindrical shank, h8 tolerance, and a drilling depth of 5 x diameter. It is a technical solution for professional drilling operations in compatible metallic and plastic materials.Features:- High-performance standard twist drill bit made from HSS high-speed steel.- Fully ground body for precise concentricity.- Type N point with good centering and reduced feed pressure.- Cylindrical shank with h8 tolerance for precise clamping.- Drilling depth of 5 x diameter for professional work in metal and plastics.Specifications:- Diameter Ø: 11.25 mm- Overall length: 142 mm- Cutting length: 94 mm- Standard: DIN 338.- Material: HSS.- Execution: fully ground.- Cutting direction: right-hand cut.- Point sharpening: Type N, ground normal helix point.- Point angle: 118°.- Helix angle: 20°-30°.- Flute profile: normal.- Core: normal.- Tolerance: h8.- Shank: cylindrical.- Drilling depth: 5 x diameter.Applications or recommended uses:- Drilling in steel up to 900 N/mm².- Drilling in aluminum.- Drilling in brass.- Drilling in plastics.- Secondary use in bronze.- Secondary use in cast iron. tradeinn Bricoinn
