Henglong specializes in manufacturing professional rock drilling consumables. Our taper chisel rock bits deliver dependable penetration for diverse mining and stone processing projects. These tools handle ferrous ore extraction including iron and manganese, non-ferrous deposits such as gold, silver and copper, alongside natural stone like marble and granite. When deployed in rock strata graded F8–14, operators typically achieve 15–18 meters of drilled footage under standard field conditions.

We maintain a broad portfolio of taper rock bits, including cross (horseshoe) and flat chisel profiles. Our chisel-style rock bits have earned solid market traction across Saudi Arabia and perform remarkably well when boring into tough hard rock layers.

This tool is engineered for shallow boreholes up to 5 meters deep, with applicable hole sizes ranging 20–45 mm. It pairs perfectly with lightweight handheld jackhammers such as Y6, Y10 and Y24. Common field applications cover blast hole drilling in stone quarries, shaping rough stone blocks, and secondary rock fragmentation on smaller boulders. It works seamlessly with hexagonal drill steels (12 mm or 22 mm) with taper angles of 4°, 6°, 7°, 11°, 12°.
