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
