Working Principle
The Kaishan K3 DTH drill bit operates on the principle of down-the-hole percussion. High-pressure air is delivered through the drill pipe to the DTH hammer, which drives the bit's piston in a rapid reciprocating motion. This piston strikes the bit's shank, transmitting powerful impact energy to the carbide buttons on the bit face. Simultaneously, the bit is rotated slowly, allowing the buttons to crush and fracture the rock. The air then flows through flushing holes in the bit, carrying rock cuttings up the annulus to the surface. This combination of impact and rotation creates efficient rock breakage, while the flushing action prevents regrinding and keeps the hole clean. The K3's design optimizes this process by ensuring uniform button loading and effective air distribution, resulting in high penetration rates and extended bit life.

Frequently Asked Questions
What is the recommended hole diameter for the Kaishan K3 DTH drill bit?+
The K3 is available in diameters from 76mm to 152mm. The specific diameter should be selected based on your DTH hammer size and desired hole diameter.
What rock formations is the K3 suitable for?+
The K3 is designed for medium to hard rock such as granite, basalt, limestone, and sandstone. It performs well in both abrasive and non-abrasive conditions.
How do I choose between hemispherical and ballistic buttons?+
Hemispherical buttons are ideal for hard, abrasive rock, offering longer life. Ballistic buttons provide faster penetration in softer, less abrasive formations.
What is the expected service life of a K3 bit?+
Service life varies depending on rock conditions, drilling parameters, and operator skill. Under normal conditions, you can expect 200-500 meters of drilling before regrinding or replacement.
Is the K3 compatible with other brands of DTH hammers?+
Yes, the K3 is designed to fit standard DTH hammers with splined shanks. Please confirm the shank type and dimensions before ordering.
What is the minimum order quantity?+
We accept orders starting from one piece for sample evaluation. However, for best pricing and shipping efficiency, we recommend ordering in bulk.
