What is Button Bit?

There are several different types of button bits. For instance, you can find a Retrac button bit or a Taper button drill bit. However, when it comes to drilling, a button bit is the most common tool for this task.

Button bit is a type of geological drilling tool that is used to bore through rock, creating cylindrical holes in the ground. While there are many different types of button bits, It is composed of two parts: a skirt body and a carbide button.

The button bit is made up of a tungsten carbide button inlaid on the drill bit body.

The buttons on the button bit are responsible for actually cutting into the rock or soil, while the machine body rotates and moves the tool forward. Because of its simple design, effective function, and relatively low cost compared to other drilling tools, button bit has become a popular choice among geologists and environmental scientists worldwide. 

So whether you’re drilling into shale or clay, buckle up and get ready to learn all about this innovative drilling technology!

  1. Retrac button drill bit

Retrac button drill bits are known for their high wear resistance on medium-hard and hard rock formations. They are made from alloy steel and are heat-treated to improve surface hardness. They are also available in a variety of sizes. The standard size is 12 buttons, and larger bits are available in sizes 13 and 14. The thread drill bits are available in two thread types: T38 MF and T51 extension.

The Uniface bit is a combination of features that will add value through higher productivity, better blasting results, and lower rock excavation costs. The Uniface bit is also expected to have a wider range of applications than its predecessors, and it has less restrictive changeover boundaries. The Uniface Retrac bit also features a stepped-spline Retrac skirt.

  1. Taper button drill bit

A Taper button drill bit is a popular type of rock drilling tool that comes in a variety of diameters and taper degrees. It is typically used for drilling in hard rocks. These bits are also commonly used in jackhammer drills and air-leg rock drills. Taper button drill bits have a sharp point for maximum penetration and rock fracture.

The service life of a Taper button drill bit depends on the quality of the internal parts of the bit, the correct selection process, and the method of use. Inappropriately selected and used tapered button drill bits will not perform well, and may result in premature failure.

  1. Kelleg button bit

The Kelleg button bit is a diamond-protected rock drill bits that are designed to reduce drill bit wear and increase drill time in difficult rock formations. This tool also provides lower CO2 emissions and longer uptime for operators. Its diamond-protected buttons also increase drill string uptime and increase safety by reducing the need for frequent drill bit changes.

Kelleg recently introduced several new bit families. The premium tricone bit, for instance, doubles the drilling distance and is equipped with patented features. Its TRI-CONNECT technology improves the drilling speed, reduces cone erosion, and extends bit life by 60%. Moreover, the new line of TRICON hammers incorporates an air-bearing design, which minimizes bearing deviation and improves bearing life.

  1. Carbide button bit

Carbide button bits are designed with enhanced wear protection. The FA carbide geometry provides increased wear protection in contact locations, on the button face, and in areas where the cutting forces are high. This design also helps extend bit life and fracturing rates. It also helps reduce matrix wear. 

These features combine to provide better performance in tough rock applications. Buttons with this advanced design are ideal for use in hard rock applications.

Carbide button bit is made from tempered alloy steel and precision-fitted with high-quality carbide buttons. It meets tight tolerances and offers superior downhole performance. It comes in a wide range of styles and diameters, including Xtreme, Standard, and Retrac versions.
