Powerful & Fast Drilling: This core drill is equipped with a robust 3000W motor and spins at 800 RPM, delivering fast, efficient drilling. It handles holes up to 8 in (200 mm) with a 1/4-7 in threaded output shaft—ideal for heavy-duty 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
