Product Desciption
Products description
Tungsten carbide buttons are mainly used for high and low pressure DHT drill and hydraulic Screw-in drill and so on.
They are suitable for hot insert or cold pressing bit inserting process, With some of the materials used in the welding process. These products are stable in quality, Excellent in performance, can meet or exceed the domestic advanced level.
We are developing carbide grades use in crushing and recycling industry. Tire, plastic, metals and trashes that needs to break down and recycle. Weariness, toughness and resistance to acidy working environment are essential properties. Specific develop grades working with different crushing materials improves the runtime of your equipment.

Grewin Button Bits advantage:
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.
(1)Thread: R22, R25, R28, R32, R35, R38, T38, T45, T51, ST58, T60
(2)Diameter: 38-127mm.
OEM and ODM--- We can design and manufacture according to customers's samples or drawings of the Bit Dia., No. Of air/water holes, carbide button shape and the face shape.
Super Quality--- Our button bit is made with high quality of best quality alloy steel bar and tungsten carbides, through heat treatment so that it can withstand the toughest rock drilling demands, and transmit intensive impact energy into the rock with the least possible loss of energy.
Global Reputation--- The taper drill bit is widely used in metallurgy mine, geological exploration, water conservancy construction, electricity, traffic, tunnel, quarry, national defence stone project etc. Our clients
Are all over the world, like Germany, Spain, Italy, Russia, Japan, India, Australia, Mexico, Colombia, Brazil,
Chile, South Africa...Etc. We have very good reputation worldwide!
