Spool set High speed steel (HSS) DIN 338 Spiral Grinding with self-centering 10 Units

If you like to take care of every detail in your home and own the latest products that will make your life easier, purchase Spool set RUKO High speed steel (HSS) DIN 338 Spiral Grinding with self-centering 10 Units at the best price. The RUKO drill bit set consists of 10 units made from high-speed steel (HSS), designed to deliver high performance across a wide range of drilling tasks. Each bit has an approximate diameter of Ø 8 mm and a total length of 117 mm, featuring a helical design that facilitates efficient material removal during use. Its bright surface and precise finish ensure high concentricity and rotational accuracy, minimizing vibrations and enhancing drilling quality. The tip is ground conically with split point technology according to DIN 1412 C, promoting slip-free drilling starts and improved cutting efficiency. It has a 118º cutting angle and a spiral angle between 20 and 30º, carefully calibrated to optimize performance and suit a wide variety of materials. Diameter tolerance is h8, 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 alloyed and non-alloyed steel and cast steel (approximate strength up to 900 N/mm²), 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.
