Sandvik has announced the launch of its new DD322i, a highly-automated, compact, twin-boom drill which is ideal for small-scale tunnelling and underground development.
Sandvik DD322i is a versatile drill that can be utilised in mining or tunnelling applications, and provides a high level of performance, accuracy and reliability. Sandvik DD322i has a new carrier and design, and can tram in small headings, tight corners and intersections thanks to its compact size, low profile cabin and Boom Control While Tramming option.

“Sandvik DD322i was very successful and well-received by our customer during the field testing in Finland earlier this year,” says Jari Talasniemi, product manager for development drills. “The site reported that almost 60 percent of their development drilling during the trial period was completed using the DD322i. It performed extremely well from day one and the Boom Control While Tramming feature was useful for their operation.”
The Boom Control While Tramming option allows the operator to simultaneously control the two booms while tramming, ensuring improved control when moving the drill and reducing potential risk of boom damage. The new SB55i booms with two roll-overs ensure improved drilling performance and accuracy, as well as high flexibility to drill crosscut and bolt holes. The DD322i can also be equipped with features such as semi-automatic drill bit changer and tele-remote drilling to make underground operations safer and more productive.
Sandvik DD322i provides flexibility for operations, starting from small size drifts up to 58 square meter coverage area, reaching up to 6.8 meters high and 9.5 meters wide. The new SB55i booms provide 19.3 square meters side coverage, which is over 48 percent more than its predecessor, the DD321.
The low-profile cabin has been redesigned and the new larger glass doors offer 55 percent more visibility, maximising safety and improving operator comfort while creating a modern, spacious and ergonomic working environment. Larger displays provide an improved user interface and the DD322i is compatible with the company’s digital offering, including Sandvik DrillConnect, iSURE, AutoMine, OptiMine and My Sandvik.
Scalable automation packages and tele-remote drilling are available as options for the DD322i, enabling better drill utilisation and continuous working hours over shift changes and during blasting and ventilation hours.
“Sandvik DD322i offers versatility and flexibility, and sets a new standard for automated features in the company’s underground drilling portfolio,” Talasmiemi says.
