API 14-3/4'' Steel Rock Milling Cutter Tunnel Boring Machine Components CE / ROHS / FCC

API 14-3/4'' steel body pdc rock drilling tools Steel Dovetail Milling Cutter

It can meet different drilling requirements in all rock formations and apply in mining,quarry and tunneling.

We can supply a full range of different diameter designs according to the customer's requirements.

We select highstrength structure alloy steel and carbides with best quality to ensure the drill body and alloy body can achieve uniform wear,thus the service life of bits will be increased.

Product Introduction

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. We can supply long skirt and short skirt Tapered Button Bits.

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 will

prevent the bit from spinning.

4 • Suitable for small hole range

• Widely used in Dimensional Stone Quarrying Industry
• Widely used in Underground Mining Industry
