Compared to taper chisel and cross bits, our high-quality air pressure DTH bits offer advanced technology, longer primary drilling time, and higher drilling efficiency. These button bits come in various types, including hemispherical, conical, and parabolic button, each designed for specific drilling needs.
Our hemispherical button bits are known for their high bearing capacity and abrasive resistance, while the conical and parabolic button bits are ideal for high drilling speed and low abrasive resistance.
Made with top-grade raw materials and subjected to special heat treatment, our tapered button bits, featuring tungsten carbide inserts from Boart long year, are widely used in Hand Hold (short-hole) drilling systems for dimensional stone quarrying.
With diameters ranging from 30mm to 50mm and taper degrees of 4, 6, 7, 11, and 12, our premium alloy tapered drill steel with Hexagonal shanks of 22mm and 25mm ensures strong delivery capacity that meets customer requirements. The number of buttons available includes 4, 5, 6, 7, 8, and 9, with 7 buttons being particularly popular for handheld (short holes) and blast drilling systems.
