Longer rods mean less rod changing.
The HCR1800-D20II is equipped with longer guide shell to accommodate a longer starter rod. As a result, you’ll have less rod changing time, faster drilling and a lower overall cost per hole.
- Longer guide shell accommodates a 20′ starter rod
- Field proven rod changer holds four 20′ extension rods
- Travelling centralizer keeps rod from warping
- Equipped with the newly developed HD828 drifter, offering a blow range of 2700-3300 bpm
- High-efficiency 477 cfm air compressor, capable of cleaning up to a 5″ hole diameter
- Ergonomically designed wide cabin offers comfortable work environment
