The button bits have the performance of high hardness, wear-resisting, anti-corrosion, anti-bending, and suitable for the harsh environment. Our button bits and drill rods choose high quality steel material and tungsten carbide inserts, superior performance, stable quality, widely used in quarrying, mining, railway, highway, hydroelectric power and other energy construction project.

Tapered button bits connected with tapered drill rods for drilling work and perforating operations. It mainly used in mine of secondary breaking, anchor bolt support, the roadway tunneling etc. It has good dust discharge effect and has strong blasting ability, and the fast drilling speed.

Tapered drill steel H22/ Hex25 are made of hexagon hollow drill steel, suit for shallow hole drilling operation in small pneumatic rock drilling or hydraulic jack hammer. The head of the tapered drill steel is conical, the tapered drill steel to match with the button bits to drilling, usually used for drilling, reaming and other quarry, coal mine, roadbed, construction etc. drilling project. The tapered drill steel are used with tapered button bits, in different length to used in different drilling condition. The commonly taper 7degree, 11degree and 12degree, diameter 23mm or made in 22mm diameter or others based on your ask.

Threaded button bits are suit with hydraulic rock drilling or pneumatic jack hammer, thru different thread type to connect with different extension rods for drilling project. Mainly used in underground mining, outdoors mining etc. field in fast drilling speed.
