Advantage of our thread rock button bit:
1. Threaded drill bits are equiped with the hydraulic drilling
jumbo and used for crush rock, which are widely used in the tunnel
construction, large scale mine (open and underground) and large
section tunnel advance in metal mine.
2. Our tools can make all kinds of threaded drill bits, that
include R25, R28, R32, R35, R38, T38, T45, T51,ST58, GT60, ST68 and
so on, and the head diameter range from 41mm to 127mm.
3. Our R&D team will develop the sharpest industry "teeth", the
most suitable bits for different application. The bits with sharp
buttons are suit for harrd and mid-hard rock, and have excellent
wear resistence and driving speed. The bits with round buttons are
extensively used in hard rock with high abrasion and impact
resistance.
4. Our button bit is made of top quality steel and tungsten carbide
same with well-known brand in the world. For the technic, we take
“hot-insertion” processing procedure to insert the buttons into the
bit. Optimized designs improve the drilling efficiency. And
automatic production line ensure the quality stability of product.
Strict requirements of heat-treatment guarantee durability of the
bits.
