Tungsten Carbide Taper Shank Button Drill Bit for Rock Mining

(1)Taper angle: 4° , 4° 46, 6° , 7° , 11° , 12°
(2)Models: Chisel/cross/button bit
(3)Diameter: 20-45 mm
(4)Button bit shape: Spherical/parabolic
(5)Socket inside diameter: 15/19/22/25mm

Our tapered drill bits are made with high quality alloy steel bar and tungsten carbides, through heat treatment.

1. Tapered chisel bit
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 bit
Used under any rock drilling condition and mainly used for hard or very hard rock formation because of it's comprehensive adaptability. Compared with taper chisel bits, taper cross bits have a better drilling performance because of 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 taper chisel and cross bits, button bits have higher technology, much longer primary drilling time and higher drilling efficiency. According to the tungsten carbide insert, button bits can be divided into types of hemispherical, conical 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.
