Threaded Rock Button Drill Bit Hemispherical Ballistic Parabolic Conical Button Type
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.
We can provide a wide range of rock drill button bit for you:
Button Bits
Components - Button bits are categorized by a variety of criteria: bit diameter, skirt length, skirt diameter, wall thickness, and gauge clearance angle, face design, and button insert types.
Skirt Designs intro - Our button bit skirt designs can be split into two categories: Retrac and Straightrac.The Retrac skirt features an extended body, with cutting edges or ribs designed into the skirt. This design ensures easy removal and completion of the bit in adverse ground conditions.The Straightrac skirt features an angled flute design with an extended skirt body that maintains 360° contact in the hole. The Straightrac design has been field tested and proven to provide straight holes in even the most adverse ground conditions.
Face design -
BR - Button Recessed – Ideal for straight hole applications in broken ground, button recessed bits are characterized by a unique “drop center” face design.
BF - Button Flat – Defined by their flat face design, these general purpose bits are designed to be effective in medium to hard ground conditions.
BC - Button Chisel – With a distinct chisel shape, this fast-penetrating style of bit is perfect for abrasive conditions, and is often utilized in tunneling applications.
BD - Button Dome – Featuring a clearly defined raised profile, this style of bit is used primarily in reaming applications in soft ground.
