All Metal Hotend Kit for CR-10S PRO: This is a drop in All Metal Conversion kit for the CR-10S PRO. Our uniquely designed cooling block eliminates need for a thermal tube. By having a separate thermal tube inside the cooling block, it allows for faster heat dissipation. The thermal heat break is made from Grade 5 Titanium Alloy to provide excellent thermal isolation between the heater and the cooling block. Titanium is extremely strong material and offers almost 3x lower thermal conductivity than stainless steel, creating more defined meltzone. ?What's in the box? 1X CR10S PRO aluminum Cooling Block 1X Titanium Heat Break 1X Aluminum Heater Block Brass Plated Wear Resistant MK8 .4mm Nozzle Silicone Sock
