What is tappered button bit

Tapered button bit is a type of rock drilling tool used in drilling operations for mining, quarrying, tunneling, and construction. It is also known as a tapered drill bit or a button bit.

The tapered button bit has a conical shape, with a smaller diameter at the base and a larger diameter at the top. The bit has several hardened steel buttons or inserts on the front surface that are shaped like cones or pyramids. These buttons are made of a hard and wear-resistant material, usually tungsten carbide, that can withstand high temperatures and pressures.

During drilling operations, the tapered button bit is rotated and pushed into the rock formation. The buttons on the bit tip break and crush the rock, creating a hole. The tapered shape of the bit helps to maintain the hole's diameter, while the buttons provide better penetration and faster drilling rates.

Tapered button bits come in a range of sizes and shapes to suit different drilling needs. They can be used with hand-held drills, pneumatic drills, or hydraulic drills, and can be used for drilling in various types of rock formations, including soft, medium, and hard rock.
