FAQ

When should I rent this hand-held core drill instead of a rig-mounted core drill stand?

This hand-held drill is ideal when you need quick setup, portability, or access to tight spots where a stand cannot be bolted or vacuumed down. It is commonly used for: drilling plumbing drain penetrations through foundation walls; running electrical conduit through cinder block; installing HVAC line sets; coring basement walls in tight corners; and boring anchor holes in masonry. If you need holes larger than 6 inches, deep multi-foot vertical slab coring, or effortless 90-degree alignment without holding the drill weight, rent a rig-mounted core drill instead.

What bit sizes and drilling depths can this drill accommodate?

This Cardi unit accepts diamond core bits up to 6 inches in diameter. Standard rental bits typically drill up to 12 to 14 inches deep, and a 12-inch extension rod is available for rent if you need to bore completely through thick concrete or foundation walls.

Can I use this core drill dry, and how do I supply water on the jobsite?

No, this core drill must be operated wet; running diamond core bits dry will overheat the motor and glaze or melt the diamond segments. You can connect it directly to a standard garden hose spigot, or if water is not available on site, you can supply water from a 5-gallon bucket using a small garden-hose pump. Gap Power also rents Rent a Diamond Core Drill, Hand-Held, DRY DRILL if your jobsite does not allow you to use water.

What electrical circuit or generator is required to power this tool?

The drill runs on standard 120-volt AC power with an 18-amp motor, meaning it requires a dedicated 20-amp outlet to prevent nuisance breaker tripping. If you are working off-grid, it requires a minimum 5,000-watt generator. Always use a heavy-gauge (12 AWG or 10 AWG) extension cord to prevent voltage drop and motor damage.

Can this drill cut through steel rebar embedded in concrete?

Yes, wet diamond core bits are designed to grind through both aggregate and steel reinforcement rebar. When the bit hits rebar, you will notice drilling slow down; maintain steady water flow and gentle, consistent pressure without forcing the tool, allowing the diamonds to grind through the metal.

How do I safely handle bit binding and torque kickback while drilling handheld?

The drill features an electronic clutch to reduce sudden shock, but binding in aggregate or rebar can still twist the tool sharply. Always maintain a balanced stance and a firm, two-handed grip on both handles, and ease off pressure if the bit begins to chatter or bind. Avoid core drilling from an unstable stepladder where a sudden twist could throw you off balance.

How easy is this core drill to transport?

Weighing only 16 pounds, the tool is compact and easily fits into the trunk or back seat of any passenger car or pickup truck. You will also have plenty of space for rented core bits, extension rods, and water supply accessories.
