152mm High Air Pressure DTH Button Bit for Hard Rock Drilling

DTH(Down-The-Hole) hammer button bits especially 152mm drill bit is made of premium high-strength alloy steel and carbide inserts.It has excellent durability and wear-resistance characteristics.The hard rock penetration capability is strong. The impact energy can reach the bottom of the hole directly, and the speed is 3 to 5 times faster than that of the rotating drill bit. DTH hammer drill bits for rock drilling, quarrying, and water well drilling use,witch can provide high drilling efficiency. Their robust design ensures consistent, reliable performance, even in the most demanding drilling environments.

The 152mm DTH hammer button bit is specifically designed for high-efficiency drilling in hard and abrasive rock formations such as granite, basalt, quartzite, limestone, and sandstone. Manufactured from premium high-strength alloy steel with wear-resistant carbide buttons, it delivers exceptional durability, long service life, and outstanding penetration performance. By transmitting impact energy directly to the bottom of the hole, the bit achieves drilling speeds that are typically 3 to 5 times faster than conventional rotary drilling methods. It is widely used in mining blast hole drilling, quarrying operations, water well drilling, foundation construction, slope stabilization, and tunneling projects. Its robust design ensures reliable performance, excellent hole straightness, and reduced drilling costs, making it an ideal choice for demanding drilling environments that require high productivity and consistent results.
