Button bit is widely used for rock drilling , blasting holes and other drill works in quarries, coal mines, road and dam constructions and other similar project.
A comprehensive range of taper button bits, cross bits and chisel bits with 6, 7, 11, 12 degreetaper.

1 Long life

2. Lower consumption

3. Wide selections of drill bits

4. Delivery quickly

5. Suitable for small hole range
6. Widely used in Dimensional Stone Quarrying Industry
7. Widely used in Underground Mining Industry

We can supply long skirt and short skirt taper 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. Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Drillers choose tapered button bits for faster drilling penetration rate.

Different taper sizes have different characteristics when it comes to the "knock-off" index – the smaller angle will prevent the bit from spinning.
