For tapered Drill Bits, our factory have chisel bits, cross bits and button bits, all with various size, smooth design and very good quality, etc. All drill bits are made of high quality raw material and through special heat treatment. We have been exporting a large quantity to over 30 countries and regions such as Australia, U.S.A, South Africa, Japan, Norway and Saudi Arabia, etc.
1. Tapered chisel bits
The tapered 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 Y6.

  2. Tapered cross bits  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. Taper Cross Bit is mainly used for hard or very hard rock formation.

  3. Tapered button bits 
Comparing with tapered chisel bits and tapered cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency, so that the button bit is popular among the users.
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.
