Description:YG15 Good strength and less wear resistance, for bits of rotary hammer rock drills and heavy rock drills, for hard and very hard rocks. porosity of carbide blank for increasing the transverse rupture strength (TRS). Carbide VS HSS drill bit LKALLOYApr 20, 2020 · High-quality drill bits are generally made of carbide and high-speed tool steel while the former can cut two to three times faster than the latter. The carbide drill bit is made tungsten carbide powder as matrix and cobalt powder by pressing and sintering as its binder. It usually contains 94% tungsten carbide, 6% cobalt and 1% other metals

Sample available US7597159B2 - Drill bits and drilling tools including An abrasive wear-resistant material includes a matrix and sintered and cast tungsten carbide pellets. A device for use in drilling subterranean formations includes a first structure secured to a second structure with a bonding material. An abrasive wear-resistant material covers the bonding material. The first structure may include a drill bit body and the second structure may include a Wear of cemented tungsten carbide percussive drillbit Design of the drillbit and selection of the Cemented Tungsten Carbide (CC) grade for drillbit inserts are crucial for efficient percussive drilling. This study presents the results of an experimental campaign executed with the aim to identify the distinctive wear mechanisms and behaviour of different CC grades.
