Products introduction:

Pulanka drill bitR type top hammer drill bits include thread connection of R22,R25,R28,R32,R38 . the main diameter that is 32mm,35mm,38mm,45mm,48mm,51mm,64mm.(1.25inch,1.4inch,1.5inch,1.75inch,1.9inch,2inch,2.5inch)

Button 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.

• Recommended for eliminating hole deviation

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