Durable Metal Tapered Drill Bit Low Breakage With Spherical And Ballistic Shaped

Thread button drill bits are produced by premium alloy steel bar and tungsten carbides. Through heat treatment, we offer industry-leading strength and penetration rates for more productivity so that get max. drilling performance for rock drills with long life. Besides, we can design customized thread button drill bits according to different drilling application and satisfy drilling soft rock, loose-medium rock and hard rock needs.

Threaded Drill Bits cover regular, retrac and reaming types. With stronger button-fixing ability, longer service life, better wear-resistance and impact-resistance performance, they are widely used in tunneling, underground mining, open pit mining, anchoring and other large-scale construction projects.
