More features

• 💥【Heavy-Duty Handheld Water Drill 】Our water drill features a pure copper motor, equipped with a safety clutch, stepless speed adjustment, and a self-priming pump, supporting both dry and wet drilling operations. supporting you to drill holes in a variety of surfaces with a 1.25-4inches/ 3.17-10.16 cm diameter hole capacity. Moreover, equipped with three industrial-grade drill bits which are the diameter of 1.25in/2.5in/4in, all with 1-1/4" thread for your convenience when drilling
• 💥【Wet and Dry Drilling】This handheld core drill is equipped with a self-priming water pump assembly featuring a flexible hose, enabling both wet and dry drilling operations. Choose freely based on site conditions. No need to connect to a water tap—just a small bucket of water allows it to automatically draw water for cooling the drill bit. Wet drilling effectively reduces bit wear, absorbs and minimizes high-frequency drilling noise, extends machine lifespan, and significantly reduces dust during operation. This protects operator health and meets eco-friendly construction requirements.
• 💥【Powerful pure copper motor 】Our handheld core drill rig is with 1900W powerful motor,designed for drilling in reinforced concrete, stone, asphalt, marble, ceramic, walls, floors, etc.,Power output remains stable with robust overload capacity, effortlessly handling reinforced concrete walls. Ideal for projects requiring frequent operation.
• 💥【Stepless Speed Variator】 This drill features a stepless speed control system, allowing the rotation speed to be freely and linearly adjusted between 0-1900 RPM based on pressure applied. At the start of drilling, a low speed enables the drill bit to smoothly “center” on the wall surface, preventing slippage and deviation that can occur during high-speed starts. This ensures more precise hole placement and dynamically adapts to different wall materials (brick walls/concrete/reinforced concrete) by matching the optimal rotation speed in real time.
• 💥【Overload Protection Clutch】 The water drill features a built-in overload protection clutch. When drilling encounters rebar or foreign objects causing a jam, the clutch automatically disengages to effectively prevent equipment damage and machine rebound injuries. It also includes a start switch lock function to prevent accidental activation, providing dual safety assurance for every operation.
• 💥【Versatile Application Range】:This versatile handheld diamond core drill is designed to meet the highest professional standards. Driven by a powerful motor, it drills through tough materials—including reinforced concrete, asphalt, brick, and stone—with speed and precision. Ideal for a wide range of tasks, it excels in installing water lines, electrical conduits, air conditioners, range hoods, and stair railings, as well as in highway guardrail repair and drainage projects.
