33mm Diameter R25 Threaded Button Bit With YK05 Carbide Grade For Rock Drilling
As a professional rock drilling tool manufacturer, Henglong supplies heavy duty R25 threaded button bits built for reliable penetration and consistent borehole quality. Optimized to maintain hole straightness and cut rock smoothly, these carbide tipped bits deliver longer service life and help operators cut overall fuel consumption on site.
Our R25 drill string configuration minimizes tensile shock waves during percussive drilling. Improved fatigue strength lowers premature wear, boosting operational uptime, fuel economy and drilling stability for light duty top hammer rigs.
Key Advantages
YK05 grade carbide inserts offer strong wear impact resistance for extended bit lifespan
Precise thread machining ensures tight connection, less energy loss during percussion drilling
Stable hole straightness reduces rework and improves overall drilling efficiency
Multiple customizable options (skirt, face, carbide shape) to fit varied rock conditions
Lower shock load design cuts premature wear, saving operational fuel maintenance cost
