Product Description

Product Features
SRM (Slide Bearing-Rubber Sealing Milled Teeth) bits can load a higher WOB in normal RPM condition. It applies in different formation from very soft to very hard matched with different cutting structure.
Product Features:
-Slide bearing is applied
-Hard alloy is welded on the surface of tooth to increase the wearing resistance performance
-Cone bearing is silver coated which provides more loading ability and anti-seizure ability
-O sealing ring is made of HNBR which is more corrosion and high temperature resistant; larger sealing ring cross section increases sealing adaptability
-Steel ball locked cone provides more security and is applicable to high speed rotation.
-250 ºC high temperature and anti-corrosion lubricant is applied which the high temperature resistance performance of bit sealing lubricating system.
-Optimized milled teeth surface weld improves the anti-corrosion performance of drill bit
-Optimized milled teeth quantity and teeth arrangement structure give full play to the cutting ability and cutting speed of drill bits.
