{"product_id":"set-di-fresa-a-corona-hss-14-24-mm-41-1102","title":"HSS Core Drill Bit Set, 14 - 24 mm","description":"Suitable for all core drilling machines with 19 mm Weldon shank, and stationary drills, using a quick-change chuck. It is possible to easily drill holes in pipes, profiles and overlapping materials (for long holes).\n\nAn advantage of the core drill over twist drills is that the entire drilling surface is not machined, but only a thin ring. As a result, the effort is much lower. Furthermore, no pre-drilling is necessary, the core is ejected through the ejector pin. These advantages result in up to 40% labor savings.\n\u003cdiv class=\"col col-12 col-md-6\"\u003e\n\n\u003ch3\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/h3\u003e\nSupplied in a metal case\n\n\u003cstrong\u003eContents:\u003c\/strong\u003e\n\u003cul\u003e\n \t\u003cli\u003e14 mm\u003c\/li\u003e\n \t\u003cli\u003e16 mm\u003c\/li\u003e\n \t\u003cli\u003e18 mm\u003c\/li\u003e\n \t\u003cli\u003e20 mm\u003c\/li\u003e\n \t\u003cli\u003e22 mm\u003c\/li\u003e\n \t\u003cli\u003e24 mm\u003c\/li\u003e\n\u003c\/ul\u003e\nRecommended cutting speed:\n\nVc = approx. 20 – 25 m\/min.\n\n\n\n\u003cdiv class=\"col col-md-6\"\u003e\n\n\u003ch3\u003e\u003cb\u003eTechnical specifications\u003c\/b\u003e\u003c\/h3\u003e\n\u003cdiv class=\"table-responsive table table-detail\"\u003e\n\u003ctable border=\"0\" cellspacing=\"0\" cellpadding=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\" width=\"307\"\u003eDrill diameter\u003c\/td\u003e\n\u003ctd valign=\"top\" width=\"307\"\u003e14 - 24 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\" width=\"307\"\u003eDrilling depth\u003c\/td\u003e\n\u003ctd valign=\"top\" width=\"307\"\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\" width=\"307\"\u003eShaft\u003c\/td\u003e\n\u003ctd valign=\"top\" width=\"307\"\u003eWeldon 19 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eLogistics\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping: 5–9 business days (7 days for the South).

For large diameter holes in steel, a core drill is more efficient than an oversized twist drill, which requires much more power. Suitable for drilling in pipes, profiles, and overlapping surfaces.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003e19 mm Weldon shank — which machines does it work on?\u003c\/summary\u003e\n\u003cp\u003eThe 19 mm Weldon shank is the standard for portable magnetic core drills and for pillar drills with a Weldon chuck.
