A full-scale stand-integrated core rig built for large-diameter work up to 14 inches. A single charge delivers enough power to drill four 10-inch holes through reinforced concrete. It is well suited for heavy-load coring on new commercial construction and infrastructure jobsites where access to power is limited—such as running large HVAC duct penetrations or major water supply and drain pipe openings.

A cordless model designed specifically for handheld operation, combining excellent mobility with a strong safety profile. It handles cores up to 6 inches, and a patented clutch combined with AUTOSTOP™ technology instantly arrests kickback if the bit binds during handheld use.

It is well suited for applications where setup time needs to be eliminated and work needs to be completed quickly—including confined spaces and elevated or scaffold work where there is no room to anchor a stand, and jobsites that require moving rapidly between multiple pipe penetrations.

A highly versatile cordless model centered on handheld use that supports both wet and dry drilling. A patented clutch prevents over-spinning, allowing safe handheld operation in either mode. From dry coring in indoor spaces where water cannot be used to high-precision wet drilling with the included stand attached, it is well suited for the wide variety of tasks that come up on renovation jobsites where working conditions change day to day.

Milwaukee Is Built for Contractors Who Need to Eliminate
Power Setup Time and Protect Against Kickback

Every model in the lineup runs on battery power, which means generators and extension cord runs are eliminated entirely. The ability to start drilling immediately on jobsites where power has not yet been connected makes Milwaukee a strong fit for contractors who want to cut prep time and put more hours into productive work.

The handheld models feature a patented clutch and AUTOSTOP™ technology that instantly shut down rotation the moment the bit binds, arresting sudden kickback. They are well suited for jobsites where physically reducing the risk of operator injury in confined spaces and on scaffolding is a priority.

This site also features diamond core drills from a wide range of other manufacturers. Use this information to find the product that best fits your specific operational requirements.

Strengths of Milwaukee

Cord-free mobility and a complete system that streamlines the entire coring workflow

The MX FUEL™ high-output battery system—capable of powering heavy-duty equipment—means drilling can begin immediately even on jobsites where generators and extension cords are not an option.

Beyond the ability to handle core diameters up to 14 inches without a power cord, the ecosystem of dedicated accessories—including stands, water tanks, and vacuum pumps—is a further advantage. Rather than relying on the drill motor alone, the full system can be configured for end-to-end operation from anchoring to water supply, significantly improving overall jobsite workflow and efficiency.

Patented safety technology for precise, safe handheld coring

AUTOSTOP™—which automatically stops rotation the moment a core bit binds—combined with the patented clutch, virtually eliminates the risk of injury from sudden kickback during handheld use.

An LED level that functions as a built-in bubble level and a pressure gauge that indicates the correct feed force further support accurate, perpendicular drilling. From small-diameter handheld work to large-diameter stand-mounted operations, the system delivers a consistently precise and safe working environment regardless of the operator's experience level.

Milwaukee Maintenance & After-Sales Support Network

Milwaukee's "eService" platform supports a fast turnaround repair process, with most repairs completed within 7 to 10 business days from the time the unit is received.

The warranty terms are also worth noting for their transparency: purchases from authorized dealers receive warranty coverage automatically^*, with no complicated registration process required. At service centers nationwide, manufacturer-certified technicians perform all repairs using genuine parts only—ensuring that even equipment pushed hard on demanding jobsites is maintained to a consistent quality standard.

Milwaukee Diamond Core Drill: Project Case Studies

Road excavation work completed in-house without waiting for a subcontractor

When subcontractor scheduling delays were holding up road excavation and test pit work, a contractor brought in the MX FUEL 14-inch Cut-Off Saw to handle asphalt and concrete cutting independently.

The saw started reliably regardless of temperature and was ready to use immediately on arrival. The team was able to carry out all the necessary cutting work in-house without waiting on outside help. Used alongside the water supply kit for effective dust control, the result was a three-day schedule delay avoided.

Manhole coring completed same day it was needed

When an unplanned coring job came up inside an electrical manhole, a contractor brought in the MX FUEL Core Drill to core through the concrete walls.

The drill was easy to set up in the tight space, and the clutch and AUTOSTOP features allowed the work to proceed safely and confidently. All required coring was completed the same day—four holes drilled in approximately two hours—allowing pipe preparation work to begin before the end of the shift.

Milwaukee Consumables & Bit Information

The lineup includes a broad range of application-specific options: wet bits, dry bits, heavy-duty variants, and a dedicated series for prestressed concrete.

Bit diameters range from 5/8 inch up to a maximum of 14 inches, and the bits are compatible with both MX FUEL™ cordless machines and corded models. Pricing is not listed on the official website, so exact costs should be confirmed directly with an authorized dealer.
