Mold Steel gear * 1pcs
1. The extrusion wheel uses imported die steel NAK80 as the raw material, which is better than the extrusion wheel made of brass and stainless steel 316;
2. Factory hardness can reach HRC37-43, pure steel, refining treatment, good cutting performance. It is currently the best extrusion wheel for 3D printer, and its inner diameter is optimized by two designs of D-shaft and O-shaft to adapt the stepper motor better, which have solved the loosening, slipping and losing steps in the traditional extrusion wheel;
3. CNC wire cutting processing, uniform tooth step, close biting, durable and wear-resistant, greatly improving the printing quality and use period. It is the real high-quality extruded wheel, please rest assured to buy.
