Reduced labor through advanced digital controls

Hilti's premium coring systems feature advanced digital controls, including the Cut Assist automated drilling function. The system continuously manages feed pressure and water flow digitally, enabling fully automatic drilling completion once the unit is set up.

On large-scale infrastructure jobsites requiring hundreds of consecutive holes, this eliminates the need for operators to remain stationed at the machine throughout the process.

Enhanced safety with Active Torque Control

To improve safety during handheld operation, Hilti tools incorporate Active Torque Control—a feature that instantly detects sudden torque spikes caused by bit binding in concrete.

By electronically arresting unexpected kickback that could otherwise result in workplace injuries, the system reduces risks from human error and supports the stringent safety management required on large-scale construction projects.

Hilti Diamond Core Drills Keep Schedules Moving and
Are Built for Large-Scale Infrastructure Jobsites

Hilti products are well suited for large-scale infrastructure work where hundreds of holes must be drilled in sequence under strict safety standards and high productivity demands. The design leverages digital automation and kickback prevention to keep projects on track while reducing dependence on individual operator skill.

Pairing the top-of-the-line DD 250-CA with the Cut Assist automated drilling solution unlocks the ability to handle large-diameter coring and reduced-crew operation requirements. The ease with which the system can be scaled to match jobsite size and safety standards is a key advantage of choosing Hilti.

Hilti Maintenance & After-Sales Support Network

Hilti Group operates globally as a company that goes beyond product sales to offer comprehensive equipment management services, including repair and maintenance. With a network of more than 120 countries^*, the company maintains a support structure capable of handling tool servicing and technical consultations in each region. (As of March 23, 2026)

Repair requests can be submitted online or by phone, covering the entire process from on-site pickup to return delivery. Repairs are performed by trained technicians using genuine parts, and for registered tools, the process can proceed smoothly without a proof of purchase.

Hilti Fleet Management offers a comprehensive, fixed monthly tool management service that centralizes everything from equipment use to repair and maintenance under a single program—helping to reduce the operational burden on large-scale jobsites running many machines simultaneously.

Hilti Diamond Coring System: Project Case Study

Precision and schedule control achieved on large-scale bridge maintenance drilling

During maintenance work on the Forth Road Bridge in Scotland, a large-scale drilling operation spanning a total length of 17,000 meters was carried out. Hilti scanning equipment was used to locate existing rebar, survey instruments were used for layout marking, and the diamond drilling system was then deployed for the actual coring work.

By unifying the entire workflow—from measurement and layout to drilling—under a single Hilti system, a high volume of holes was completed with precision. This project demonstrates that Hilti is adopted as a complete system, not just as individual tools, on high-precision, high-volume jobsites such as infrastructure maintenance.

Hilti Diamond Core Drill Consumables & Bit Information

The coring performance of a core drill depends on both the machine's specifications and the characteristics of the bit used with it. Hilti's coring system offers two main bit series—SPX-A and SPX-L—selected based on the base material and operating environment.

The SPX-A is designed to pair with cordless drills, offering a specification that maximizes output per charge while increasing drilling speed. It is a practical choice for efficiently advancing work on jobsites where mobility is a priority.

The SPX-L supports on-site tip replacement via the X-Change module. Combined with the stable output of a corded machine, it delivers performance well suited for continuous coring into high-strength concrete.
