1. Taper chisel bit

The taper chisel bit is widely used in drilling holes with depth less than 5 meters and diameter ranged in 20-45 mm by light-duty rock drill, like Y20, Y24.

  1. taper degree: 4°46″, 6°, 7°, 11° and 12°
  2. diameter: 28mm to 45mm
  3. socket inside diameter: 19mm / 22mm / 25mm

2. Taper cross bit

The taper cross bits can be used under any rock drilling condition because of it's comprehensive adaptability. Compared with taper chisel bits, taper cross bits have a better drilling performance because carbide tips on cross bits doubled, which means carbides shape are cross type on drill bits.

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
