Product Details

## Overview The Kaishan K5 DTH drill bit is a 5-inch class down-the-hole button bit designed for high-efficiency rock drilling in mining, quarrying, water well, and construction applications. As a core component of the DTH drilling system, it is engineered to withstand extreme impact and abrasion while delivering consistent penetration rates. The K5 is compatible with standard 5-inch DTH hammers and is available in flat face, convex face, and concave face designs to match various rock formations. ## Technical Features Manufactured from high-quality alloy steel, the K5 undergoes advanced heat treatment to achieve an optimal balance of hardness and toughness. Tungsten carbide buttons are precision-pressed and brazed into the bit body, ensuring excellent wear resistance and impact strength. The bit features optimized flushing holes that direct air to the cutting face, effectively removing cuttings and cooling the buttons. Its splined shank provides a secure connection to the hammer, while the robust body design minimizes breakage in tough drilling conditions. The K5 is available in diameters ranging from 130 mm to 152 mm, with various button shapes (spherical, ballistic, conical) to suit different rock hardness. ## Applications The Kaishan K5 DTH drill bit is widely used in open-pit mining, quarrying, water well drilling, geothermal exploration, and foundation engineering. It performs exceptionally well in hard and abrasive rock such as granite, basalt, and quartzite. Whether drilling blast holes, water wells, or anchor holes, the K5 delivers reliable performance and extended service life, reducing downtime and overall drilling costs. ## Why Choose Kaishan K5 With decades of expertise in drilling equipment, Kaishan ensures each K5 bit meets strict quality standards. The combination of premium materials, precise manufacturing, and rigorous testing results in a drill bit that maximizes productivity and minimizes cost per meter.

Working Principle

The Kaishan K5 DTH drill bit operates as part of a down-the-hole drilling system. Compressed air is supplied through the drill pipe to the DTH hammer, which contains a piston that strikes the bit's shank at high frequency. The impact energy is transmitted through the bit body to the tungsten carbide buttons, which crush and fracture the rock. Simultaneously, the bit is rotated slowly, allowing the buttons to chip away the rock in a circular pattern. The exhaust air from the hammer travels through the flushing holes in the bit, cooling the buttons and lifting cuttings to the surface. This combination of impact and rotation enables efficient drilling in hard rock formations. The K5's design ensures optimal energy transfer, effective flushing, and minimal wear, resulting in high penetration rates and long service life.
