34mm/36mm /38mm 7 Buttons 22mm Shank Carbide Taper Button Bit

Our taper drilling tools include taper drill bits and taper drill rod, and taper drill bits come into two types, taper button drill bits, and taper chisel drill bits. These drill tools are mainly equipped on rock drilling equipment, well drilling equipment and oil field equipment. They are widely used for rock drilling, blasting holes and other drill works in quarries, coal mines, rod and dam constructions and other similar projects.
Description: 
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. 
Made with high quality of raw material through special heat treatment, especially, tungsten carbide of tapered button bits are from Boart long year, widely applied in Hand Hold (short-hole) drilling system for dimensional stone quarrying. At now, we are exporting the huge qty of Q7- 33- 7 22-80, Q9 -45 -12 22- 71 for Indian quarry and Norway, Finland quarry. 
Diameter of bits from 30mm to 50mm with 4 ,6,7,11,12 degree, premium alloy tapered drill steel with Hexagonal.22mm and Hexagonal.25mm,The deliver capacity are very strong and can completely meet customer's requirements on delivery design, number of buttons is 4,5,6,7,8,9,7 buttons is very popular for hold held (short holes ) and blast drilling system. 

Taper Button Bit
Advanced type of taper drill bits when compared with taper chisel bits and taper cross bits. With carbide buttons hot pressed on bits bodies, it has good drilling performance and life time. Usually used for hard or very hard rock formation.

Tapered Button Bits
Comparing with taper chisel and cross bits, button bits have higher technology, much longer primary drilling time and higher drilling efficiency. According to the tungsten carbide insert, button bits can be divided into types of hemispherical, conical 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.
We are specialized in producing reinforced cut-off wheel and grinding wheel, ultra thin cutting disc for metal and stainles steel. The cutting disc and grinding disc are the preferred choice in all kinds, in the metal, structural steel, iron, weld, foundry, stainless steel, aluminum, concrete, masonry, brick, block, stone, and other industries. We progresse year by year together with our business partner based on advanced technique, ongoing research and years of experience.
