• Powerful & Fast Drilling: This core drill boasts a robust 2500W motor and dual-speed settings (535 RPM/920 RPM), delivering fast, efficient drilling. It handles holes up to 10 in (260 mm) with a 1/4-7 in threaded output shaft—ideal for tough tasks
• Superior Hole Quality: Our diamond core drilling machine features both wet and dry drilling. The wet drilling option flushes out debris and cools the bit with water, reducing dust and improving hole smoothness—great for indoor renovation work
• Enhanced Security & Stability: The built-in clutch automatically stops the drill when it hits hard resistance to save you and the core drill machine. Plus, the water-seal-free design avoids common water seal failures and keeps your workflow steady
• Built to Last: Crafted with a lightweight yet tough aluminum body, this core drill rig resists wear and tear. It has wheels for easier transport. The PVC water hose is crack-resistant, and the steel output shaft delivers consistent accuracy
• Professional Kit: This concrete core drill includes ten premium drill bits (1 in, 2 in, 3 in, 4 in, 5 in, 6 in, 7 in, 8 in, 9 in, 10 in) that cut through reinforced concrete, brick, marble, and more. It is ideal for all your drilling needs
