Henglong is a professional maker of top-hammer rock drilling threaded button bits. We build these rock bits in multiple thread sizes, outer diameters, skirt styles, face layouts and carbide profiles, to match varied site drilling demands.
Our threaded button bit lineup covers the R-series and T-series, including R22, R25, R28 and R32 models, with diameters ranging from 38 mm to 51 mm. These bits are widely deployed for underground mine drift excavation and tunnel boring.
The popular R25 38 mm button bit comes fitted with 7 tungsten carbide buttons. It pairs well with 0.5 m, 0.8 m and 1.2 m drill rods, making it a solid pick for natural stone quarrying. This bit is commonly matched with YT28, YT27 and YT29A rock drills (shank size: 22 × 108 mm).
We adopt YK05 / YK10H grade tungsten carbide, balancing excellent wear resistance and impact toughness. Premium alloy steel blanks plus hot-insertion locking technology firmly fix carbide buttons into the bit body, greatly lowering the risk of button drop-out during heavy percussion drilling.
For highly abrasive rock conditions where service life matters more than fast penetration, spherical carbide buttons are a reliable alternative.
R22, R25 and R28 threaded button bits are stocked in the following diameters:
Built for drift driving, tunnel works and quarry rock drilling, these threaded drill bits are compatible with a wide range of drill rods, including MM-thread hex rods for lightweight top hammer rock drills.
