<p><strong>Set of 6 TCT holesaws for metal in sizes 22-65mm</strong>. The blades are made of <strong>cemented carbides</strong>, which are characterized by much greater hardness and resistance to high temperatures compared to high-speed HSS steel. Designed to make larger diameter holes in steel, cast iron, non-ferrous metals, wood, plastics, etc. a HSS pilot drill used to increase the precision of cutting. The spring mounted on the guide drill allows you to easily remove the spoil.</p><br/><p><strong>Product features:</strong><br />high quality for maximum precision of cutting<br />carbide-tipped blades - 10 times longer service life compared to standard bi-metal holesaws<br />carbide teeth can be re-sharpened<br />HSS pilot drill bit with a titanium layer<br />a spring on the guide drill designed to remove the spoil<br />holesaws have a collar to prevent drilling<br />solid construction reduces vibrations, and thus significantly increases the precision of drilling<br />replaceable pilot drill and spring<br />the use of cooling lubricant is recommended to extend the service life of the holesaws<br />safe handle, chamfered on 3 sides, prevents slipping of the hole saw in the drill chuck<br />the whole set is packed in a handy aluminum suitcase</p><br/><p><br /><strong>Technical Specifications:</strong></p><br/><p>Material: <strong>tool steel, tungsten carbide, HSS steel</strong></p><br/><p>Number of holesaws in the set: <strong>6</strong></p><br/><p>Drilling diameters: <strong>22, 30, 35, 45, 50, 65 mm</strong></p><br/><p>Maximum drilling depth: <strong>25 mm</strong></p>
