Developed from Zhuoshi's original Matrix drill-bit design, this range is made for professional dry drilling in porcelain, ceramic tile, gres and sintered stone. The engineered surface pattern distributes diamond exposure across the working area, supports efficient debris removal and helps maintain a stable cutting action during repeated drilling. Compared with conventional vacuum-brazed core bits, the Matrix structure is designed to improve drilling efficiency and performance consistency when used with the correct speed and pressure. The range includes small-diameter precision bits, standard core bits and distributor-ready sets, with connection options for angle grinders and professional drilling systems. Available specifications vary by model and can be selected according to the material, hole diameter, machine and working conditions. Zhuoshi supports OEM and private-label projects with color options, laser marking, packaging development and pre-shipment inspection. Send us your target material, required diameter, thread and expected order quantity, and we will recommend the appropriate Matrix drilling solution.
