The newly introduced DD 150-U Diamond Coring System from Hilti is designed to allow the operator to drill by hand or with a core stand in wet or dry conditions. The new DD 150-U, introduced at The Rental Show last week in New Orleans, has a 6-inch capacity for drilling the most popular sizes of holes for anchoring, blind holes and through holes. This system can handle a variety of base materials from reinforced concrete to brick, concrete block and natural stone.

Performance is optimized in the wet drilling mode and suitable for rig-based drilling in concrete for pipe penetrations in plumbing, heating and air conditioning installations, for cable trays and ducts and for the installation of railings and barriers. The DD 150 is also designed for setting large-diameter anchors and reinforcing bars that require hand-guided wet drilling.

The unit can also be switched to dry drilling when necessary for hand-guided, dry drilling applications such as drilling in masonry for pipe penetrations in plumbing, heating and air conditioning installations and chimney and stove vent installations. And, on dry applications where dust is a concern, the Hilti Dust Removal System may be used.

The DD 150-U features high motor performance and three-speed gearing for optimum drilling speeds. It also has a 360-degree adjustable side handle with integrated dust and water management functions. It can be ordered with a standard 1 ¼-inch threaded chuck or with a quick-connect chuck that does not require the use of any tools to remove the core bit.
