| titleOfInvention | Drill bit can be replaced to quick detach |
| abstract | This content mainly relates to a drill bit can be replaced to quick detach, and it is mainly by wear -resisting matrix, compound piece cutter body, and parts such as broken stem stem constitute, and wear -resisting matrix be whole vacuum quenching and tempering, and the surface adhesion has tungsten carbide coating, and compound piece cutter body is the cutting tool that can go on replacing with the supporting use of wear -resisting matrix, the appearance is worn and torn in the use, but pair recombination piece cutter body is changed fast under falling the condition of piece. Drill bit in the past mostly is overall structure, and the in -process then needs to change whole drill bit if appear damaging drilling to cause the wasting of resources. A drill bit structure, than traditional drill bit, the matrix abrasion strength is high, all cutter bodies that drill bit can be replaced to quick detach provided is but that pair recombination piece cutter body is dismantled and is more renewed the cutter body and a wasting of resources, reduction in production cost that the stem stem all adopts the fastening screw fastening with the matrix, and it is swiftly convenient to change, makes things convenient for the workman to operate and avoid promptly. |
