Thread Button bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 Mpa to 260 Mpa compressive strength). Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture.
1) Bit body: Normal type and retrac type
2) R thread: R22 R25 R28 R32 R38
3) T thread: T38 T45 T51 T58 T60
4) Bit diameter: 32mm-127mm
5) Bit face shape: Flat face and drop centre
6) Tungsten carbide (Buttons): Spherical, ballistic and conical.
Thread button drill bits are made by high quality alloy steel bar and tungsten carbides. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. Besides, we can design customized thread button drill bits according to different drilling application, and custom drill bits are applicable to drill soft rock, loose-medium rock and hard rock.
