Description

This type of bit is well known for its wear resistance and high speed drilling on soft to medium-hard rock formations (between 70 Mpa to 180 Mpa compressive strength). Featuring ballistic tungsten carbide inserts that is known to have high penetration rate, but has weak configuration against carbide fracture.

• Widely used drifting and tunneling
• Bit face design is ideal for medium-hard to hard abrasive rock

Color: Green or Based on Customer requirements

Material: Tungsten carbide and high strength alloy steel

Processing: CNC milling and proprietary heat treatment process

Type: R38 Button Bit Ballistic Buttons

 

Perfect designs, tungsten carbide and skirt steel , We provides leading strength and penetration rates for more
productivity, excellent straightness and hole clean quality, get max drilling performance to save up fuel cost rate.

We can design and manufacture according to customers' samples or drawings of the diameter., buttons and flushing holes quantity, button shape and face shape. Our button bit is made by high quality tungsten carbides and steel, through heat treatment so that it can be used for hard rock drilling, and transmit intensive impact energy into the rock with the least possible loss of energy. Comparing with tapered chisel bits and tapered cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency. According to the buttons, thread button bits can be divided into the types of Dome, Ballistic, etc.

 

Applications

• Underground mining
• Tunneling

 

Competitive Advantage

• High grade tungsten carbide inserts
• Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment
