1, Features
1. With carbide buttons hot pressed on bits bodies, Tapered Button Bits have a very good drilling performance and long life time. Different diameters and taper degrees are available to suit different applications in mining, quarrying etc.
2. 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.
3. 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 willrevent the bit from spinning.
4 . Suitable for small hole range
• Widely used in Dimensional Stone Quarrying Industry
• Widely used in Underground Mining Industry
2. Applications
The taper cross bits can be used under any rock drilling condition because of it's comprehensive adaptability.
Taper chisel bit is mainly used for hard rock, tapered cross bits and tapered button bit are mainly used for fissural
rock.The tapered cross bit is mainly used for diging into mine laneway and blasting holes in all drilling works
the taper drill rod. For different rock, we choose the different alloy to extend the working life of the taper cross bits.
