Ruko Din 338 Uni Hsse-co 5 Helical Ø 7.5 Mm Metal Drill Bit 10 Units. RUKO DIN 338 UNI HSSE-Co 5 Helical Ø 7.5 mm Metal Drill Bit: Precision and Power for Cordless DrillingUnlock superior performance and unmatched efficiency with the RUKO DIN 338 UNI HSSE-Co 5 Helical Metal Drill Bit. Engineered specifically for the demands of modern professionals and craftsmen, this high-performance twist drill bit is meticulously developed for optimal use in portable cordless drills and screwdrivers. Experience a new standard of precision when working with materials up to 5.0 mm thick, achieving clean, accurate results with every use. This individual 7.5 mm drill bit is your ultimate solution for demanding metal drilling tasks where accuracy and tool longevity are paramount.The standout feature of this drill bit is its revolutionary 3-flat shank. This intelligent design allows for exceptional clamping within any standard drill chuck, requiring minimal tightening force. The result is a secure, slip-free connection that ensures optimal power transmission from your drill directly to the cutting edge. Say goodbye to frustrating bit slippage and the need to overtighten your chuck, this shank guarantees a stable and efficient drilling experience, preserving both your tool and the drill bit itself.At the forefront of its design is the ultra-fast 135° split-point tip. This specialized geometry provides exceptionally high centering accuracy, a critical advantage for manual applications with cordless drills. It bites into the material instantly, eliminating walking or slipping, even when starting a hole on curved or uneven surfaces like pipes and profiles. This immediate engagement translates to faster, safer, and more precise drilling from the very first rotation.Engineered for the cordless era, this drill bit helps you work longer. By significantly reducing the required cutting force, it places less strain on your drill´s motor, leading to longer battery life per charge. The advanced flute and tip design work in harmony to cut through metal with less effort, allowing you to complete more holes and stay productive on the job site.Durability is further enhanced by the distinct black bevel on the cutting edges. This treatment significantly increases wear resistance and effectively prevents cold welding and the formation of built-up edges, especially when drilling tougher materials. This ensures the bit maintains its sharpness for longer, delivering consistent performance over an extended lifespan.Complementing these features is the aggressive 40° clearance angle (helix angle). This steep spiral design facilitates perfect and rapid chip removal, clearing the way for the cutting edges to work efficiently. This advanced chip evacuation allows for higher cutting speeds while maintaining incredible stability and accuracy, resulting in perfectly round, clean holes with minimal burring.
