Rotary Drilling Cutting Pick Solution

Strong impact resistance, suitable for 60-80MPa rock formations

The body adopts kencoat hardfacing technology, with large-particle WC as the hard phase

Wear condition after penetrating 1.8m into rock

Harsh engineering conditions >>

A building construction project in Guangzhou encountered complex limestone formations with a hardness of 60-80MPa. Traditional rotary drilling cutting picks wore quickly and had low efficiency, and even 7 machines still struggled to meet schedule and cost requirements. When the core barrel penetrated about 2 meters into the rock, it was blocked and required switching to a roller cone drill.

Severe challenges >>

To improve construction efficiency and reduce cutting pick wear, the project department urgently needed a high-performance rotary drilling cutting pick product.

Kennametal solution >>

In response to the project's specific needs, Kennametal provided the KCDS05-59-25 cutting pick for testing. This cutting pick has a relatively large body size and a moderate alloy diameter, designed to meet the requirements of high wear resistance and high efficiency in hard rock construction.

Impressive results >>

In testing in 60-80MPa limestone formations, after this cutting pick penetrated 3.3m into rock, compared with a certain brand's product with alloy studs, its alloy tip wore gradually and its body wear-resistant layer was consumed slowly, with wear resistance improved by 10-15% and rock penetration efficiency increased by 8-10%, solving the construction challenge.
