If you like to take care of every detail in your home and own the latest products that will make your life easier, purchase <b>Spool set RUKO High speed steel (HSS) DIN 338 Spiral Grinding with self-centering 10 Units</b> at the best price.<br><br><p>The <b>RUKO drill bit set</b> consists of <b>10 units</b> made from <b>high-speed steel (HSS)</b>, designed to deliver high performance across a wide range of drilling tasks. Each bit has an <b>approximate diameter of Ø 8 mm</b> and a total length of <b>117 mm</b>, featuring a helical design that facilitates efficient material removal during use. Its <b>bright surface</b> and precise finish ensure high concentricity and rotational accuracy, minimizing vibrations and enhancing drilling quality. The tip is ground conically with <b>split point technology according to DIN 1412 C</b>, promoting slip-free drilling starts and improved cutting efficiency. It has a <b>118º cutting angle</b> and a <b>spiral angle between 20 and 30º</b>, carefully calibrated to optimize performance and suit a wide variety of materials. Diameter tolerance is <b>h8</b>, ensuring precise compatibility with standard chucks and tools. These bits cut clockwise, a common feature in quality tools for efficient cutting. They are ideal for working with materials such as <b>alloyed and non-alloyed steel and cast steel (approximate strength up to 900 N/mm²)</b>, as well as various cast irons: grey, malleable, nodular, and pressure-cast. They are also suitable for drilling sintered iron, alpaca, graphite castings, and non-ferrous alloys like aluminum, bronze, and brass. Their Chinese origin does not compromise quality, reflecting a practical balance between good performance and affordable price. Overall, this RUKO set offers reliability and durability for professionals and hobbyists needing a robust, precise drill bit set suitable for demanding tasks on various metal materials.</p><br><br><ul><li>Standard: DIN 338</li><li>Material: High speed steel (HSS)</li><li>Units: 10 Units</li><li>Shape: Spiral</li><li>Characteristics: Grinding with self-centering</li><li>Approx. diameter: <ul><li>Ø 8,5 mm</li><li>Ø 8 mm</li></ul></li><li>Cut size: 75 mm</li><li>Approx. dimensions: 117 mm</li><li>Colour: Grey</li></ul>
