This product is a dedicated taper bit for shallow hole drilling operations. It is manufactured in accordance with relevant national standards for drilling tools, featuring the core characteristics of "high adaptability and anti-stuck drill". It is a frequently used shallow hole drilling component for small-scale mines, small-scale infrastructure projects, and geological exploration scenarios.
 Core Competitive Advantages
Taper quick-fit adaptation: Adopting a taper connection structure, it can directly fit into the taper hole of the corresponding specification drill rod without requiring threaded screwing, reducing the assembly and disassembly time by 60% compared to threaded drill bits, meeting the rapid operation requirements of handheld drilling machines.
Anti-stuck drill and easy powder discharge: The matching design of the tooth part and the powder discharge groove enables quick discharge of rock powder from shallow holes, reducing the occurrence rate of stuck drill by 40% compared to ordinary drill bits; even in the operation of fractured rock layers, the flexible disengagement of the taper connection can reduce the risk of retention in the hole.

Product Description

Tapered button bits 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.
