Winged Reamer & Hole Opener
Winged reamer is welded with carbide cutting edges on the interlaced surfaces of the three wing plates and the cutting edges are punctation distributed. For this reamer, the cutting edges of wing plates adopt stepped stratified cutting and they are short and punctation distributed, so the resistance and energy needed for rotation are greatly decreased. Winged reamer requires high strength of wing plates. It shows strong ability to overcome obstacles and it can get through smoothly even if meeting large construction waste such as stones. However, generally specialized hole clearing process should be carried out after reaming. It's generally suitable for reaming in hard soil layer.
Main componentsCore shaft, 16Mn steel sheet, carbide bit
SpecificationThe winged reamers produced in our factory have specifications of φ150mm~φ400mm. Threads connected to core shaft can be matched according to users' requirements.
Product maintenanceClean the mud and sand pasted on bit surface every time after back reaming process. Meantime, check the wear of connecting threads and the conditions of cutting edges of wing plates. Pay attention and don't collide or heavily press when transporting and stacking in order not to damage cutting edges. Coat thread dope and screw thread protector on threads.
