3800W 2-in-1 Electric Diamond Grinder & Polisher Tackle floor/wall renovation, stone polishing, and concrete leveling effortlessly—no ladders, no back strain. This versatile tool combines a powerful motor, flexible telescopic rod, and 3-head grinding design to cut project time and labor costs, ideal for both large-scale jobs and tight spaces. Core Features 1. Powerful 3800W Pure Copper Motor High-torque, heat-resistant pure copper motor handles tough tasks: marble polishing, concrete leveling, granite processing, and metal descaling. Built-in automatic overheating protection (auto-shuts off when overloaded) and dual safety switches (prevents accidental starts) for long-lasting, safe use. 2. 6-Speed Adjustment (700-65000 RPM) Fine-tune speed to match materials (cement, red brick, marble) and tasks (rough grinding, fine polishing, descaling). Low gear compatibility with ordinary sandpaper avoids material damage; quick disc replacement (works with diamond/resin/sandpaper discs). 3. Flexible Telescopic Rod (90-130cm) Adjust length via rod replacement to 90-130cm (35.4-51.2")—locks securely at your preferred height, reducing back fatigue during long work hours. Seamlessly switches between upright floor mode and handheld wall mode: reach high walls, tight corners, or floors without bending or ladders, boosting comfort and efficiency. Extra anti-vibration side handle (top/side threads) for two-hand control, ensuring precision and even pressure. 4. 90° Dead-End-Free Grinding Precise 90° edge grinding for stairs, corners, and baseboards—no dead spots. Removable edge guard for easy access to tight areas; minimized debris splatter for safer operation. 5. 3-Head 4" Diamond Grinding 3 high-hardness 4" (100mm) diamond grinding heads expand coverage, enabling fast removal of terrazzo, epoxy coatings, and concrete residue. Synchronized 3-disc design improves surface flatness, reduces wear, and accelerates large-scale floor refinishing/leveling. 6. Dust Control & Heat Dissipation Built-in dust shroud with vacuum port (compatible with shop vacuums) traps airborne debris, protecting the motor and reducing cleanup. Porous heat dissipation design keeps the motor cool; external brush port allows 10-second carbon brush replacement for non-stop Specifications Power: 3800W Pure Copper Motor Voltage: 110V Disc Size: 3 × 4" (100mm) Diamond Heads Speed Range: 6 Speeds (700-3000 RPM) Weight (Without Pole): 7.25kg (16 lbs) Telescopic Rod Length: 90-130cm (35.4-51.2") What’s in the Box 1 × 3800W Electric Diamond Grinder & Polisher 1 × 90-130cm Telescopic Rod 3 × Diamond Grinding Discs 3 × Polishing Pads 3 × Sandpaper Discs 3 × Adhesive Discs 1 × Anti-Vibration Side Handle 1 × Quick-Release Wrench 2 × Spare Carbon Brushes Safety First Always wear PPE: safety glasses, dust mask, ear protection, and work gloves.
