K3 Excavator Drilling Mast Attachment


Fast, Efficient & Powerful

The K3 Drilling Mast Attachment uses 10ft )3 m) long drill rods with the high torque JT-200 Series of rotation heads for geothermal, geotechnical and foundation drilling applications.

The JT-200 series of rotation heads feature a 2-3/8" (60 mm) center bore for mud or air flushing or grout injection with the included 90 degree, max 2,500 PSI (172 bar) top swivel. The rotation head drive flange can be coupled with an adapter to fit the customers drill rods or casings for various applications and drill methods.

All excavator attachments include T legs for safe horizontal transport and storage of the mast. A simple 2-hose connection allows for easy attchment to the carrier machine (some carrier machines required additional hydraulics to operate the mast) The rear mount plate is built to suit the specified carrier machine/s.

The K3 can be fitted with additional features and tooling to suit a variety of applications and drill methods currently available.
