RUKO 2141175 - Pack de 5 brocas helicoidales DIN 338, tipo N HSS, fresada-rectificada, con autocentrado (Ø 11,75 mm)

Ruko Hss Din 338 Type N Serie 214 11.75mm Drill Set 5 Pieces. This RUKO HSS DIN 338 Type N drill set features five 11.75mm fully ground twist drill bits crafted from high-strength HSS. Engineered for precision and stability, the Type N geometry with a 118° point angle ensures excellent centering and reduced feed pressure for clean cuts in metals like steel, aluminum, brass, and plastics, as well as secondary use in bronze and cast iron. Boasting h8 tolerance and a drilling depth of 5x diameter, these are professional-grade tools for reliable performance. The HSS DIN 338 Type N twist drill bit is a high-performance standard drill bit made of high-strength high-speed steel. Its fully ground construction provides precise concentricity and stable performance during drilling.The Type N geometry incorporates a standard ground spiral point, a 118° point angle, and a helix angle of 20° to 30°. This configuration allows for good centering, reduces the pressure needed during feed, and promotes a regular cut in commonly machined materials.Made of uncoated HSS, it features 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 of HSS high-speed steel.- Fully ground body for precise concentricity.- Type N point with good centering and lower 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: 11.75 mm- Overall length: 142 mm- Cutting length: 94 mm- Standard: DIN 338.- Material: HSS.- Execution: fully ground.- Cutting direction: right-hand cut.- Point grinding: Type N, standard ground spiral point.- Point angle: 118°.- Helix angle: 20°-30°.- Flute profile: normal.- Core: normal.- Tolerance: h8.- Shank: cylindrical.- Drilling depth: 5 x diameter.Recommended applications or 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
