SP480 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.

SP480 bit technical parameters

SP480 drill product introduction

The SP480 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.

Drill face characteristics

Convex face

This shape is suitable for drilling soft-medium hard rock formations with low-medium wind pressure, and the steel body of the drill bit is not easy to corrode.The drilling speed is faster and the drill body wears less. The characteristic is that the tooth load is low, the wear is not serious, and the drilling speed is fast.
