R25 Threaded Button Bit with Spherical / Ballistic Buttons for Rock Drilling
Describtion
Miroc R25 type of bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 Mpa to 260 Mpa compressive strength). Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture.
• Widely used drifting and tunneling
• Bit face design is ideal for medium-hard to hard abrasive rock
The Features of the Product
1. Tapered button bits connect with tapered drill rod perfectly for drilling holes
2. Stable and mature welding technology ensure high quality of bits
3. Accurate dimension of taper degree perfectly matches the rods
4. work reliable and very cost-effective
