89mm T38 Concave Face Retrac Button Bits Rock Drilling For Hydraulic Trolley
Retractable rock drill button bit is well known for its high wear
resistance on medium-hard to hard abrasive rock formations (between
200 Mpa to 260 Mpa compressive strength).Featuring spherical
tungsten carbide inserts that is known to have strong configuration
against carbide fracture.
Thread button drill bits are made by high quality alloy steel bar
and tungsten carbides. Through heat treatment, our drilling tools
are tough enough to meet rock drilling demands and have the least
loss of energy while drilling the rocks. Besides, we can design
customized thread button drill bits according to different drilling
application, and custom drill bits are applicable to drill soft
rock, loose-medium rock and hard rock.
Threaded button drill bits are suitable for powerful percussive
drills and top hammers with high speed drifter, such as Atlas Copco
282 rocket boomer, Atlas Copco 352 rocket boomer jumbo,
AtlasCopcoD7roc, FurukawaHCR 1200, Tamrock, and Ingesoll Rand
ECM660, the products are widely used in bench and production
drilling, extensional drilling.
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. We 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.
