Rock Drill Tapered Button Bits is suitable for H22mm and H25mm taper rock drill rods use. It have three taper connection: 7°, 11°, 12°. It's widely used for hard rock(f=8~18) drilling use.
1) Tapered connection: 7,11,12
2) Alloy steel:42CrMo
3) Suitable carbide tips:YK20
4) Cross bit diameter: 30-42mm
5)Technology:hot-pressing or welding
According to the tungsten carbide insert, button bits can be divided into the types of hemispherical button, conical button and parabolic button, etc.
Button bits with hemispherical button is for high bearing capacity and abrasive resistance while conical button and parabolic button are for high drilling speed and low abrasive resistance.
When drilling, adjust the parameters of impulse and rotary with the standards of no jamming, high drilling speed and no bend of tapered drill rods.
Check the rock drill bits after each drilling. If the buttons are seriously worn, replace the button bits timely to ensure the drilling speed. If it's possible, grind the button bit for reusing. Replace the button bits once the taper worn, otherwise the buttons would be seriously abraded and even jammed.
We can design and manufature according to your requirment of diameter, number air holes and carbide button shape.
