Chisel-type bits remain a top pick for Middle Eastern markets like Saudi Arabia, favored for fast penetration in hard rock. Our tapered chisel bits are widely used for 20–45mm shallow holes under 5 meters, commonly matched with lightweight handheld rock drills including Y6, Y10 and Y24.
Typical applications cover natural stone quarrying: small hole drilling, stone block trimming and secondary rock fragment breaking.
We adopt premium raw materials and precision heat treatment for each chisel bit to boost impact resistance and service life. With stable manufacturing capacity, we support custom design and flexible delivery schedules for bulk orders.
Whether you run granite or marble quarries, or metal mines (ferrous & non-ferrous), this tapered chisel bit reduces downtime and keeps your drilling jobs efficient. Contact us for more details and bulk pricing.
