Product Details

## Overview The Kaishan L2 DTH hammer is a low-pressure down-the-hole hammer designed for efficient drilling in medium-hard to hard rock formations. As a specialized drilling tool, it converts compressed air into high-frequency impact energy, driving the drill bit into the rock while simultaneously rotating for optimal penetration. This model is widely used in water well drilling, mining, quarrying, and construction projects where reliable performance and low operating costs are essential. ## Technical Features The L2 hammer features a robust outer cylinder and a precision-machined piston that ensures smooth reciprocation and minimal energy loss. Its valveless design simplifies the structure, reduces maintenance requirements, and improves reliability in dusty and harsh environments. The hammer is compatible with standard 2-inch API drill pipes and button bits, making it easy to integrate into existing drill strings. Advanced heat treatment and high-quality alloy steel construction provide excellent wear resistance and extended service life. The optimized air passage design reduces pressure drop and improves flushing efficiency, ensuring fast hole cleaning and reduced bit wear. ## Applications This DTH hammer is ideal for water well drilling, geothermal exploration, blast hole drilling in quarries, and foundation piling. It performs well in granite, limestone, sandstone, and other medium-hard rock types. The L2 model is particularly suitable for contractors who require a balance between drilling speed and air consumption. Its compact size and lightweight design make it easy to handle and transport, while its durable construction ensures reliable operation even in remote locations. ## Why Choose Kaishan L2 Kaishan is a leading manufacturer of drilling equipment with decades of experience.

Working Principle

The Kaishan L2 DTH hammer operates on the principle of converting compressed air into mechanical impact energy. Compressed air is supplied through the drill pipe to the hammer, where it drives a piston in a reciprocating motion. The piston strikes the drill bit shank, generating a high-frequency impact wave that fractures the rock. Simultaneously, the drill string rotates slowly, indexing the bit for the next impact. After each impact, the air is exhausted through the bit holes, flushing cuttings out of the hole and cooling the bit. The valveless design of the L2 simplifies the air distribution, reducing wear and improving reliability. The hammer's internal components are precisely machined to ensure smooth operation and minimal energy loss, resulting in efficient rock breakage and extended tool life.
