SP680 DTH drill bit features advantages

Long bit life

This drill bit is relatively wear-resistant in the actual working process. Because the wear ratio of the drill bit’s cemented carbide is more than 10-20 times that of similar products, the service life of the bit has been greatly extended.

Wide range of use

Practice has proved that the bit is suitable for drilling in medium-hard formations such as carbonate rock, limestone, chalk rock, clay rock, siltstone, and sandstone.

High drilling efficiency

This drill bit has high hardness and wear resistance, and the drill bit can always remain sharp, which greatly improves the gear feed speed. While the drill speed is high, the user experience is good, which improves user satisfaction.


Because this drill bit has a fast drilling speed and long life, the number of drilling times is small, the drilling cost is greatly reduced, and it has an excellent cost performance. It is a good choice.

SP680 bit technical parameters

SP680 drill product introduction

The SP680 down-the-hole impactor is connected to the drilling bit for drilling engineering. SP480 uses high-quality steel and best-level alloy steel as raw materials, special heat treatment technology and advanced cemented carbide inserting technology, so that the drill bit can perform well even on hard rock formations, while saving energy.

This type of drill has a wide range of applications. Compared with ordinary drills, especially for drilling into 6-8 rock formations, the effect is particularly significant.

Drill face characteristics

Concave face

This head shape is suitable for all rock formations, especially in medium-hard and uniform rock formations, with small blast hole deviation and good slag discharge effect.
