<p><strong>HSS TiN drill bit set with HEX mounting.</strong> The set includes <strong>13 drills with a diameter of 1.5-6.5mm.</strong> Designed for drilling in non-ferrous metals, steel sheets and plastics.</p><br/><p>The drill bits are made of HSS high-speed steel coated with TiN (titanium nitride).</p><br/><p><strong>The TiN-coated drill bits</strong> are designed in particular <strong>for machining difficult-to-cut materials</strong>. The use of the TiN coating results in an increase <strong>in the hardness of the drills</strong>, enables the acceleration of the cutting process and allows for better quality of the machined elements. <strong>The titanium nitride layer, thanks to the reduction of the friction force</strong>, reduces sharp wear, and thus extends the life of the drill bit.</p><br/><h4>Technical data:</h4><br/><table><br/><tbody><br/><tr><br/><td>Type</td><br/><td>spiral</td><br/></tr><br/><tr><br/><td>Material</td><br/><td>HSS Steel</td><br/></tr><br/><tr><br/><td>Layer</td><br/><td>TiN (titanium nitride)</td><br/></tr><br/><tr><br/><td>Chuck</td><br/><td>HEX</td><br/></tr><br/><tr><br/><td>Diameters [mm]</td><br/><td>1.5 / 2.0 / 2.5 / 3.0 / 3.2 / 3.5 / 4.0 / 4.5 / 4.8 / 5.0 / 5.5 / 6.0 / 6.5</td><br/></tr><br/></tbody><br/></table>
