<p><strong>Hole Saw TCT</strong> for metal in size<strong> 45mm.</strong> The blades are made of <strong>carbide</strong>, characterized by significantly greater hardness and resistance to high temperatures compared to high-speed steel HSS. Designed for drilling larger diameter holes in steel, cast iron, non-ferrous metals, wood, plastics, etc. To enhance cutting precision, a guiding drill made of HSS steel has been applied. A spring mounted on the guiding drill allows easy removal of debris.</p><br/><h4>Product Characteristics:</h4><br/><ul><br/><li>High-quality construction, translating into great precision of work</li><br/><li>Blades made of carbide, with a lifespan even 10 times longer compared to standard bimetal hole saws</li><br/><li>Carbide teeth can be re-sharpened</li><br/><li>Guiding drill made of HSS steel coated with a titanium layer</li><br/><li>Spring on the guiding drill designed for debris removal</li><br/><li>Hole saw has a collar protecting against over-drilling</li><br/><li>Solid construction reduces vibrations, significantly increasing drilling precision</li><br/><li>Replaceable guiding drill and spring</li><br/><li>To extend the hole saw's lifespan, it is recommended to use cooling lubricant</li><br/><li>Safe 3-sided phased handle prevents the hole saw from slipping in the drill chuck</li><br/></ul><br/><h4>Technical Specification:</h4><br/><ul style="list-style-type: disc;"><br/><li>Materials: <strong>tool steel, carbide, HSS steel</strong></li><br/><li>Drilling diameter: <strong>45 mm</strong></li><br/><li>Maximum drilling depth: <strong>25 mm</strong></li><br/><li>Maximum revolutions per minute: <strong>500 RPM</strong></li><br/></ul>
