Product Description:
Comparing with taper chisel and cross bits, taper 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.
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.
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.
