Background and Identification
The Hilti Core Drill model DD-250E is a diamond coring drill made by Hilti, a Liechtenstein company that develops, manufactures, and markets products for construction, building maintenance, and manufacturing. The DD-250E model is sold with a motor, drill stand, base plate, wheels, adapter, and jackscrew. It is designed specifically for drilling into concrete, reinforced concrete, brick, concrete block, and natural stone. The DD-250E model is sometimes called the DD 250 BL-Diamond Coring System.
The Hilti Core Drill model DD-250E can operate at speeds of up to 2,200 revolutions per minute. The system allows users to operate the drill either by hand or with a core stand in wet or dry conditions. The drill includes an air-cooled, heavy-duty drive unit with four-speed gearing. It can drill up to 18 inches for anchoring, blind holes, and through holes. The drill’s stand has a built-in line feed that is designed to reduce user fatigue. According to Hilti, the drill’s performance is optimized in the wet drilling mode. The DD-250E model displays real-time information like a digital spirit level, gear selector, power control function, trip counter, running time counter, and service messages. Users can add stability to the coring drill using the DD-HD30 SL Jackscrew.
The Hilti Core Drill model DD-250E can be identified by its mainly red body with black accents. The name “Hilti” is printed in white capital letters above the model number “DD-250.”
