Product introduction:

Perfect design, tungsten carbide, and skirt steel, leading strength and penetration for increased productivity, excellent straightness, and hole cleaning quality for maximum drilling performance for fuel cost savings.
We can design and manufacture diameter, number of buttons and flush holes, button shape, and inclination according to customer's samples or drawings. Our button bits are made of high-quality tungsten carbide and steel, cold-treated to make them usable for hard rock drilling and to transfer the intense impact energy into the rock with a minimum of possible energy loss. Compared with tapered chisel bits and tapered cross bits, button bits have higher technology, longer drilling time, and higher drilling efficiency. According to the different buttons, tapered button bits can be divided into dome type, ballistic type, etc.
Tapered button drills are the most popular sharp drills and are available in a variety of head diameters from 26mm to 48mm. Tapered button drills by hot pressing carbide buttons on the bit skirt provide good drilling performance and excellent service life.
