Ruko Din 338 Hss Ground Self-centering Helical Ø 10.4 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Helical Ø 10.4 mm Metal Drill BitCategory: Electric tool accessoriesSubcategory: Drill bits---Elevate your drilling capabilities with the RUKO DIN 338 HSS Ground Helical Drill Bit, engineered for professionals who demand unparalleled precision and reliability. This high-performance 10.4 mm drill bit is a versatile workhorse, designed to deliver exceptional results across a wide spectrum of common materials, making it an indispensable accessory for any workshop or job site. Its superior construction and intelligent design ensure clean, accurate holes with every use, setting a new standard for efficiency and quality in your metalworking projects. Key Benefits and FeaturesUnmatched Precision with Self-Centering Split PointExperience effortless and accurate starts on any surface. This drill bit features a conical point grinding with a split point according to DIN 1412 C. This advanced geometry allows the bit to be self-centering, eliminating the frustrating walking or wandering that can occur with standard bits. You can start drilling immediately without the need for a center punch, saving time and guaranteeing that your holes are positioned exactly where you need them. This feature is critical for achieving high concentricity and rotational precision from the very first turn.Superior Performance in Metal and MoreCrafted from high-performance HSS (High-Speed Steel), this is the quintessential tool for drilling in Metal. The entire body of each individual bit is fully ground, a process that ensures exceptional straightness and dimensional accuracy. This meticulous manufacturing results in smoother operation, reduced friction, and perfectly round holes. The Type N point geometry, combined with a standard helix, provides excellent centering capabilities while requiring lower feed pressure, reducing operator fatigue and tool wear.Engineered for Durability and EfficiencyDesigned for professional work, this bit allows for a drilling depth of up to 5 times its diameter. Its optimized 118° cutting angle and 20-30º spiral angle work in harmony to facilitate efficient chip removal, preventing clogging and overheating. The right-hand cut is standard for most drilling applications, while the bright, polished surface further reduces friction. The cylindrical shank is manufactured to a precise h8 tolerance, ensuring a secure, wobble-free grip in any standard drill chuck for maximum power transfer and safety. Broad Application RangeThis high-performance 10.4 mm drill bit is the ideal choice for a vast array of materials, demonstrating remarkable versatility. It is suitable for:* Alloyed and unalloyed steel (up to approx. 900 N/mm² strength)* Cast steel, gray cast iron, malleable cast iron, and nodular cast iron* Die-cast iron and sintered iron* Nickel silver and graphite cast iron* Short-chipping aluminum alloys* Bronze and brass* PlasticsWhether you are a professional machinist, a metal fabricator, or a dedicated DIY enthusiast, the RUKO DIN 338 HSS drill bit offers the reliability, precision, and longevity required for high-quality results in all types of drills.---Technical Specifications* Diameter (Ø): 10.4 mm* Standard: DIN 338* Point Geometry: Conical Point Grinding with Split Point (DIN 1412 C)* Point Angle: 118°* Helix Angle: 20-30°* Diameter Tolerance: h8* Shank: Cylindrical with h8 tolerance* Cutting Direction: Right-Hand Cut* Surface: Bright, Fully Ground* Drilling Depth: Up to 5 x Diameter. tradeinn Bricoinn
