DK 920

The DK 920 Model drill is the culmination of efforts between Davey Kent Inc. and Western US clients to fill a niche need in the soil-nail process of foundation drilling. This machine is capable of installing soil-nails very efficiently. Most are single pass without the need to add or change drill steel.


Proven to be the most productive machine because of it’s best-in-the-world combination of articulation and stroke, the DK 920 can be utilized for almost any type of drilling required. The DK 920 is highly engineered and has proven to be stable and reliable under the most extreme job site stresses. When you need production, you need the DK 920.
