Complete Guide To Button Bits: Types, Applications, And Maintenance

Button bits are an important tool in rock drilling and mining operations. They usually come in the form of conical buttons which are made of superior materials that provide increased hardness and wear resistance. They are designed with carbide buttons which help in breaking rocks of surface materials while being drilled. Here is a comprehensive guide to understanding the button a bit better:

Type

Tapered Button Bits: This button bit is widely used in drilling rigs for blast hole drilling and exploration projects. They have a tapered body which enables easier removal from the hole once the drilling is complete.

Retract Button Bits: They are designed with retractable ballistic buttons that can either extend or retract during a drilling process. This feature helps improve drilling efficiency and increases the lifespan of the button bit.

Threaded Button Bits: These bits have a threaded connection that allows them to be attached or detached from the drilling rig as required. They are widely used in mining operations.

DTH Button Bits: These variants are used in drilling equipment for digging deep holes. They are built to withstand impact and abrasion while drilling on hard rock formations.

Depending on the project, there are many other types of button bits like flat faces, concave faces, reverse circulations, conical buttons, etc.

Applications

Mining: Button bits are used in mining operations to extract minerals from the ground. It is also used in exploration drilling, blast hole drilling, and production drilling.

Construction: Used in various construction projects for drilling, piling, and tunnelling. They are mainly used to create holes where the foundation for the building can be laid.

Geotechnical Engineering: This device is used for sampling rock and soil extracts. It helps in the collection of important data for various construction and geological studies.

Maintenance

Proper maintenance is essential to ensure the device gives assured performance while offering extended service. Here are some simple tips to keep your button bits in good condition:

Regular Inspection: Ensure that the device is thoroughly checked for damage or wear after each use. Small damages can be mended while those with extended damage should be replaced to maintain the efficiency of the drilling process.

Cleaning: After each use, the button bits need to be thoroughly cleaned. This will prevent degradation of the device while improving its drilling performance.

Sharpening: The buttons should be sharpened using a grinding machine at regular intervals. This maintains the device's overall working condition and its effectiveness.

Lubrication: Apply lubricants to reduce friction and heat on its surface during operation. This will ensure the device lasts for an extended period without incurring any major damage.
