Product Introduction
Large-Diameter Coring Anywhere the Job Takes You
Core drilling through reinforced concrete has traditionally meant running water lines, generators, and heavy corded rigs to a fixed work point. Our cordless concrete core drill breaks that dependency, using a dual 20V battery configuration delivering 40V combined output to a low-speed, high-torque gearbox that drives diamond core bits from 52mm to 162mm diameter through reinforced concrete slabs up to 300mm thick with the use of a bit extension. The drill operates on a rigid rail-and-carriage system, similar in principle to a corded rig, ensuring the bit travels in a perfectly perpendicular path regardless of operator hand pressure.
Dust and slurry management is built into the system design rather than treated as an afterthought. The standard configuration supports dry-coring with a vacuum dust shroud for indoor work where water management is impractical, and converts to wet-coring with an integrated water swivel and feed line for outdoor or large-diameter applications where dry coring would generate excessive dust. A torque-limiting clutch protects both the operator and the gearbox if the bit binds unexpectedly on embedded rebar, automatically disengaging drive before dangerous kickback can occur — an essential safety feature given the torque levels involved in large-diameter coring.
The rail base mounts via a vacuum pad for smooth concrete surfaces or a mechanical anchor point for rougher or curing concrete where vacuum seal cannot be guaranteed. A built-in bubble level and laser cross-line projector assist in achieving accurate hole placement and true vertical alignment before drilling begins, reducing the costly error of a misaligned core hole in structural or utility penetration work. The variable feed rate control on the carriage allows the operator to match advance speed to the specific aggregate hardness encountered, preventing bit overheating in dense aggregate while maximizing coring speed in standard mix concrete.
Built for utility installers, HVAC contractors cutting duct and pipe penetrations, and demolition crews preparing structural openings, this core drill eliminates the water and power infrastructure constraints that limit corded rigs to locations near a hose bib and outlet. The dual-battery platform provides sufficient runtime for multiple 100mm cores in standard concrete per charge set. For projects requiring precise, large-diameter penetrations in concrete or masonry without the logistics of a corded rig, this cordless core drill delivers genuine job-site flexibility.

Frequently Asked Questions
Q: What is the maximum core diameter?
A: 162mm standard, suitable for most HVAC, plumbing, and structural penetration applications.
Q: Can it core dry, or does it require water?
A: Both methods are supported; dry coring uses a vacuum dust shroud while wet coring uses an integrated water swivel.
Q: What happens if the bit hits rebar?
A: The torque-limiting clutch automatically disengages drive to prevent dangerous kickback when the bit binds.
Q: How is the rig mounted?
A: Via a vacuum pad on smooth concrete or a mechanical anchor bolt where vacuum seal cannot be guaranteed.
Q: What is the maximum drilling depth?
A: 200mm standard, extending to 300mm with the optional bit extension accessory.
Q: Does it include alignment assistance?
A: Yes, a laser cross-line projector and bubble level ensure precise placement before drilling.
Q: How many batteries does it require?
A: Two 20V batteries connected for 40V combined output to drive the high-torque gearbox.
Q: How many cores can I drill per charge?
A: Typically 4-6 cores of 100mm diameter in standard concrete per dual battery charge set.
Q: Is it suitable for indoor occupied buildings?
A: Yes, dry coring with vacuum dust extraction makes it appropriate for occupied building retrofit work.
Q: What is the warranty?
A: 1-year professional warranty covering the motor, gearbox, rail system, and safety clutch.
