One of the most difficult jobs in construction is digging a clean hole of accurate dimensions in a concrete structure. Hilti’s solution is to pair the DD 250-CA Diamond Core Drill with the DD AF-CA Cut Assist automatic feeder that intuitively guides the tool through the entire drilling process. The company calls this a semi-autonomous drilling system and says that contractors who use it can achieve significant productivity gains and comfort on their job sites. The DD 250-CA Diamond Core Drill uses integrated technology to provide operator guidance for proper drilling setup, and real-time drilling feedback and productivity data once drilling is complete. The smart tool is designed for a full range of applications including drilling penetrations for ducts, pipes and cables and drilling blind holes for anchoring anchors or rebar after installation. For Hilti customers with a DD 150 U diamond core drill, the DD AF-CA L automatic feeder can be used. With Hilti Cut Assist technology, operators can perform challenging drilling jobs with greater safety, comfort and reduced fatigue in challenging conditions. Smart features include automatic surface detection, drilling depth tracking, water management, hole start and through hole detection. To reduce concrete dust and stay on the right side of OSHA Silica regulations, the Hilti WMS 100 BLE water management system and automatic feeders work together automatically to provide a complete system solution.
