Product Details

## Overview Kaishan K8 DTH drill bits are precision-engineered tools for down-the-hole hammer drilling in mining, quarrying, water well, and construction applications. As a leading manufacturer of drilling equipment, Kaishan designs the K8 series to deliver high penetration rates and extended service life even in abrasive and hard rock formations. These bits are available in a range of diameters and shank configurations to match popular DTH hammers. ## Technical Features The K8 bits feature a high-strength alloy steel body heat-treated for optimal hardness and toughness. Tungsten carbide buttons are strategically arranged to maximize rock breakage and minimize wear. Multiple flushing holes ensure efficient removal of cuttings, preventing regrinding and reducing bit wear. The bits are compatible with standard DTH hammers and are available with flat, convex, or concave face designs to suit different rock conditions. Strict dimensional tolerances guarantee a perfect fit and reliable performance. ## Applications Kaishan K8 DTH bits are widely used in open-pit mining, quarrying, water well drilling, geothermal drilling, and foundation engineering. They excel in medium to hard rock such as granite, basalt, limestone, and sandstone. Whether drilling blast holes, water wells, or anchor holes, these bits provide consistent performance and long life, reducing overall drilling costs. ## Quality Assurance Each Kaishan K8 bit undergoes rigorous inspection, including material testing, heat treatment verification, and dimensional checks. With advanced CNC machining and automated brazing, Kaishan ensures consistent quality and reliable performance. The K8 series is a cost-effective choice for contractors seeking durable and efficient drilling tools.

Working Principle

DTH (Down-The-Hole) drill bits are used with a DTH hammer, which is a pneumatic percussion tool. Compressed air is supplied through the drill string to the hammer, driving the piston to strike the bit. The bit's tungsten carbide buttons crush and fracture the rock under high-frequency impacts. Simultaneously, the air flows through the flushing holes in the bit to remove cuttings from the hole bottom. The bit rotates slowly, indexing the buttons to new positions for efficient rock breakage. The combination of impact and rotation allows fast drilling in hard rock. Kaishan K8 bits are designed to withstand high impact forces and abrasive wear, ensuring reliable performance and long service life.
