Product Details

## Overview The Kaishan K80 is a premium down-the-hole (DTH) drill bit engineered for high-efficiency rock drilling in mining, quarrying, and water well applications. As part of Kaishan's extensive Drilling Tools line, this bit is specifically designed to match high-pressure DTH hammers, delivering superior penetration rates and extended service life in the most challenging formations. ## Technical Features The K80 features a 200 mm (8-inch) diameter and a flat face design with hemispherical buttons, optimized for hard and abrasive rock. The bit body is machined from high-quality alloy steel and heat-treated for maximum strength and fatigue resistance. Tungsten carbide buttons are strategically arranged to balance wear and impact loading, ensuring consistent performance. Multiple flushing holes effectively remove cuttings and cool the bit, preventing regrinding and enhancing drilling efficiency. The bit shank is compatible with standard DTH hammers, ensuring easy integration into existing drill strings. ## Applications This DTH drill bit is widely used in open-pit mining, quarrying, construction, and water well drilling. It excels in hard rock conditions such as granite, basalt, quartzite, and limestone. The K80 is particularly effective in blast hole drilling where high productivity and hole accuracy are critical. Its robust design also makes it suitable for geothermal drilling and foundation work. ## Why Choose Kaishan K80 Kaishan is a globally recognized manufacturer of drilling equipment and tools, with decades of experience in rock drilling technology. The K80 bit is manufactured under strict quality control and tested for performance and durability. By choosing the Kaishan K80, contractors benefit from reduced drilling costs, fewer bit changes, and increased overall productivity. The bit is available for immediate shipment and is supported by Kaishan's worldwide service network.

Working Principle

The Kaishan K80 DTH drill bit operates on the principle of down-the-hole percussion. High-pressure air is supplied through the drill string to the DTH hammer, which directly drives the bit's piston. The piston strikes the bit shank, transferring impact energy to the tungsten carbide buttons. Simultaneously, the bit rotates slowly, causing the buttons to crush and fracture the rock. The air then flushes the cuttings out of the hole through the flushing holes. This combined impact and rotation action allows for efficient drilling in hard rock. The design of the bit ensures that the impact energy is effectively transmitted to the rock, while the flushing holes maintain a clean hole bottom. The K80's button layout and face design are optimized to balance wear and penetration rate, resulting in a long service life and high productivity.
