RUKO 202040E - Pack de 10 brocas helicoidales Corta DIN 1897, tipo N HSS Co 5, rectificada, con autocentrado (Ø 4 mm)

Ruko Din 1897 Short Hss-co 5 Ground Split Point Helical Ø 4 Mm Metal Drill Bit 10 Units. RUKO DIN 1897 Short HSS-Co 5 Ground Split Point Helical Ø 4 mm Metal Drill BitUnlock superior performance and uncompromising precision in your metalworking projects with the RUKO DIN 1897 Short HSS-Co 5 Ground Helical Drill Bit. Expertly engineered for professionals who demand durability and accuracy, this 4 mm drill bit is the definitive choice for drilling in metal, especially challenging alloys and thin materials where stability is paramount. Its robust, short design significantly reduces the risk of breakage, providing you with a reliable tool for even the most demanding workshop environments.Crafted from a high-performance, high-speed steel fortified with a cobalt alloy, this drill bit offers exceptional thermal tempering resistance. This allows you to maintain higher drilling speeds and tackle tougher materials without premature wear, ensuring a longer tool life and consistent results. Each individual bit is ground to perfection, embodying the quality and precision that professionals expect from their tools.Unmatched Precision and EfficiencyThe advanced design of the RUKO DIN 1897 drill bit ensures clean, accurate holes every time. The conical point grinding, complete with a split point according to DIN 1412 C, provides an aggressive self-centering action. This crucial feature prevents the bit from walking or wandering on the material´s surface, eliminating the need for a center punch and guaranteeing a precise start. The optimized 135° cutting angle is ideal for penetrating hard metals with reduced thrust, making your work faster and less strenuous.Built for Demanding ApplicationsThis drill bit is specifically designed to excel where others fail. Its short and stable construction makes it perfectly suitable for working with thin materials like sheet steel, providing clean entry and exit without deforming the workpiece. The high resistance to breakage ensures you can work with confidence, even under high torque or in less-than-ideal conditions. The distinctive golden-brown surface finish is a visual indicator of the superior heat treatment process, which enhances surface hardness and durability.Versatile Performance Across MetalsEngineered for versatility, this drill bit is your go-to solution for a wide range of materials.Ideal Applications Include:* Alloyed and unalloyed steels (up to a tensile strength of approx. 900 N/mm²)* High-alloy chromium steels, such as V2A and V4A stainless steel* Acid- and rust-resistant steels* Grey cast iron and malleable cast ironThe efficient right-hand cut and 20-30º helix angle ensure smooth and effective chip removal, keeping the cutting area clear and preventing overheating for a flawless finish. The product is supplied in a convenient translucent plastic case with a red label for easy identification and secure storage.Technical Specifications:* Standard: DIN 1897* Drill Bit Type: Short Helical Drill Bit* Diameter (Ø): 4 mm* Point Grind: Conical with Split Point (DIN 1412 C)* Cutting Angle: 135º* Helix Angle: 20-30º* Diameter Tolerance: h8* Surface Finish: Golden Brown* Cutting Direction: Right-hand cut* Application: Metal. tradeinn Bricoinn
