产品介绍
Features:

|
Thread button drill bits are made by high quality alloy steel barand tungsten carbides. Through heat treatment, our drilling tools are toughenough to meet rock drilling demands and have the least loss of energy whiledrilling the rocks. Besides, we can design customized thread button drill bitsaccording to different drilling application, and custom drill bits areapplicable to drill soft rock, loose-medium rock and hard rock. |
