DCA Diamond Core Drill, 3800W, 250mm - AZZ02-250A

Core Drilling Machine 10"

The DCA AZZ02-250A is a heavy-duty 3800W (3.8 kW) diamond core drill engineered for demanding core cutting and large-scale concrete projects. Driven by a rugged 3800 W pure copper motor, this high-performance core drill delivers an impressive maximum drilling capacity of up to 250 mm (10"). To handle varied material hardness with precision, it features a 2-speed mechanical gearbox (390 / 1100 RPM) paired with a high-precision steel guide rail construction and a solid roller bracket stand. This structural combination drastically reduces vibrations, ensuring smooth vertical operation and perfectly aligned results even under extreme workloads.

Safety and durability are prioritized through a comprehensive suite of protective features, including integrated electronic overload protection to guard the internal motor and an earth leakage protection switch for operator safety. Optimized for wet-drilling applications, the unit comes equipped with a convenient water spray interface that suppresses dust particles and actively cools the diamond bit to maximize its service life. Shipped with essential accessories including a water pipe, pipe connectors, and wrenches, the AZZ02-250A serves as a reliable, high-torque workhorse for structural engineering and commercial construction.

Key Features & Benefits:

• 3800W Pure Copper Motor: Powered by a wear-resistant, heavy-duty 3800 W (3.8 kW) pure copper motor that delivers exceptional drilling force required for professional core cutting in dense reinforced concrete and masonry.

• 250 mm Maximum Drilling Capacity: Engineered to handle large-diameter core bits up to 250 mm (10"), making it ideal for utility installations, plumbing penetrations, and infrastructural construction projects.

• Mechanical 2-Speed Gearbox: Features a dual-speed gear selection (390 / 1100 RPM) that allows operators to balance torque and rotational speed according to the hardness of the material being drilled.

• Steel Guide Rail Construction: Engineered with high-precision steel tracking to deliver exact drilling alignment, reduce vibration, and ensure smooth operational movement across vertical columns.

• Solid Roller Bracket Stand: Equipped with a heavy-duty rig stand utilizing a roller mechanism to facilitate stable, smooth vertical movement and reduce operator effort during deep core boring.

• Integrated Overload Protection: Integrates an advanced electronic safety mechanism that automatically protects internal motor components from electrical and mechanical damage during extreme workloads or bit binding.

• Earth Leakage Protection Switch: Built-in electrical module designed to protect the operator from shock hazards when operating with water sources in wet construction environments.

• Integrated Water Source Connection: Supports wet-drilling applications by actively supplying water to the cutting zone, suppressing dust particles and cooling the diamond bit for an extended service life.
