According to the tungsten carbide insert, tapered button bits can be divided into the types of hemispherical button, conical button and parabolic button, etc.
Button bits with hemispherical button is for high bearing capacity and abrasive resistance while conical button and parabolic button are for high drilling speed and low abrasive resistance.  

  1. taper degree: 4°46″, 6°, 7°, 11° and 12°
  2. diameter: 28mm to 45mm
  3. carbide profile: spherical and ballistic
  4. socket inside diameter: 19mm / 22mm / 25mm
  5. carbide quantity: 4 to 8 pieces
  6. length: 50mm to 80mm
